    AlismaL.是水生和湿地植物的重要药用属。10个公认的物种。然而,主要是由于多倍体和有限的分类单元和基因采样,Alisma的系统基因组关系仍然具有挑战性。在这项研究中,我们对34种赤霉科进行了测序,包括十种泽泻中的八种,一种Echinodorus和一种Luronium,进行质体基因组的比较分析和系统发育分析。质体基因组的比较分析显示,该属内物种之间的序列相似性很高。我们的研究分析了Alisma质体的结构变化和变异,包括IR膨胀或收缩,和基因复制或丢失。系统发育结果表明,泽泻是单系的,并构成四个组:(1)A.lanceolatum和A.canalculatum;(2)A.subcordatum和A.triviale的北美进化枝;(3)A.wahlenbergii和A.gramineum;(4)来自欧亚大陆和北非的A.plantago-aquatica,其中嵌套有东亚A.因此,结果挑战了将东方A.作为一种独特物种的认识,并提高了将其视为广泛的A.plantago-aquatica的同义词的可能性。中药中著名的泽泻(Zexie)很可能源于其在亚洲悠久的种植历史中的形态变量泽泻。质体系统发育结果也支持四倍体A.langeolatum作为六倍体东亚A.canaliculatum的可能母本。
    Alisma L. is a medicinally important genus of aquatic and wetland plants consisting of c. 10 recognized species. However, largely due to polyploidy and limited taxon and gene sampling, the phylogenomic relationships of Alisma remain challenging. In this study, we sequenced 34 accessions of Alismataceae, including eight of the ten species of Alisma, one species of Echinodorus and one species of Luronium, to perform comparative analyses of plastid genomes and phylogenetic analyses. Comparative analysis of plastid genomes revealed high sequence similarity among species within the genus. Our study analyzed structural changes and variations in the plastomes of Alisma, including IR expansion or contraction, and gene duplication or loss. Phylogenetic results suggest that Alisma is monophyletic, and constitutes four groups: (1) A. lanceolatum and A. canaliculatum; (2) the North American clade of A. subcordatum and A. triviale; (3) A. wahlenbergii and A. gramineum; and (4) A. plantago-aquatica from Eurasia and northern Africa with the eastern Asian A. orientale nested within it. Hence the results challenge the recognition of A. orientale as a distinct species and raise the possibility of treating it as a synonym of the widespread A. plantago-aquatica. The well-known Alismatis Rhizoma (Zexie) in Chinese medicine was likely derived from the morphologically variable Alisma plantago-aquatica throughout its long history of cultivation in Asia. The plastome phylogenetic results also support the tetraploid A. lanceolatum as the likely maternal parent of the hexaploid eastern Asian A. canaliculatum.

    卑尔根毛虫(哇。)斯特恩布。是分布在印度喜马拉雅地区(IHR)的多年生药草。从《国际卫生条例》的不同地区共收集了8个纤毛虫种群,17个EST-SSR标记用于本研究。本研究揭示了基因座水平的中等遗传多样性,等位基因平均数(Na=7.823),平均有效等位基因数(Ne=3.375),平均期望杂合度(He=0.570),和平均香农多样性指数(I=1.264)。MSR(He=0.543,I=1.067)和DRJ种群(He=0.309,I=0.519)在种群水平上揭示了最高和最低的遗传多样性。分别。AMOVA分析表明,81.76%的遗传变异是在种群内,10.55%在人群中,7.69%在各地区之间。此外,在人群中发现了中度到高度的分化(FST=0.182),这可能表明纤毛虫种群中低至中等的基因流(Nm=0.669)。UPGMA和PCoA分析显示,八个种群可以分为两组,而结构分析将96个个体分为三组。Mantel检验表明遗传距离与地理距离呈正相关。这项研究的结果将为这种有价值的药用物种提供保护和种质管理策略的发展。
    Bergenia ciliata (Haw.) Sternb. is a perennial medicinal herb distributed in Indian Himalayan Region (IHR). A total of eight populations of B. ciliata were collected from diverse locales of IHR, and 17 EST-SSR markers were used in this study. The present study revealed moderate genetic diversity at the locus level with the mean number of alleles (Na = 7.823), mean number effective of alleles (Ne = 3.375), mean expected heterozygosity (He = 0.570), and mean Shannon\'s diversity index (I = 1.264). The MSR (He = 0.543, I = 1.067) and DRJ populations (He = 0.309, I = 0.519) revealed the highest and lowest genetic diversity at the population level, respectively. AMOVA analysis showed that 81.76% of genetic variation was within populations, 10.55% was among populations, and 7.69% was among the regions. In addition, a moderate to high level of differentiation was found among the populations (FST = 0.182), which could be indicative of low to moderate gene flow (Nm = 0.669) in the B. ciliata populations. UPGMA and PCoA analysis revealed that eight populations could be differentiated into two groups, while the structure analysis of the 96 individuals differentiated into three groups. The Mantel test showed a positive relationship between genetic and geographical distance. The findings of this study will provide the development of conservation and germplasm management strategies for this valuable medicinal species.

    BACKGROUND: The discovery and development of new phytomedicines can be greatly aided by plants because of their tremendous therapeutic benefits, efficiency, cost-effectiveness, lack of side effects, and cheaper therapies. In this regard, Quercus baloot, generally known as oak, is used in folkloric medicine for treating and preventing various human disorders, including diabetes.
    OBJECTIVE: For this purpose, the present study aimed to evaluate crude methanolic extract and various fractions of Quercus baloot for antihyperlipidemic and antihyperglycemic potential followed by the analysis of active compounds.
    METHODS: The hypoglycemic and hypolipidemic activity was evaluated in Swiss male Albino mice by administering an oral dose of 150-300 mg/kg of Q. baloot extracts in alloxan induced diabetic mice for 14 days.
    RESULTS: The results revealed that crude methanolic extract at a dose of 300 mg/kg exhibited a significant reduction in the blood glucose level (198.50 ± 1.99 mg/dl) at day 14 and the same treatment significantly increased the body weight (31.26 ± 0.27g) at day 14 in comparison to the control group. Moreover, the biochemical parameters were investigated which presented an increase in high-density lipids (HDL) (30.33 ± 0.33 mg/dl), whereas Low-Density Lipids (LDL) showed a significant decrease (105.66 ± 0.26 mg/dl). Additionally, triglyceride levels 104.83 ± 0.70 mg/dl, and total cholesterol 185.50 ± 0.76 mg/dl are significantly decreased. In serum biochemical analysis creatinine and hepatic enzyme markers, like serum glutamate pyruvate transaminase (32.00 ± 0.36 U/mg), serum glutamate oxaloacetate transaminase (34.33 ± 0.61 U/mg), and alkaline phosphatase (157.00 ± 0.73 U/mg), were significantly reduced by the crude methanolic extract at a dose of 300 mg/kg as compared to the control group. The antioxidant enzymes like Superoxide dismutase (4.57 ± 0.011), peroxidases dismutase (6.53 ± 0.014, and catalase (8.38 ± 0.014) at a dosage of 300 mg/kg of methanolic extract exhibited a significant increase. The histopathological study of the diabetic heart, liver, and pancreas showed substantial restoration of damaged tissues in the methanolic extract 150 and 300 mg/kg treated group, which supports the effectiveness of Q. baloot seeds. The gas chromatography-mass spectrometry analysis of methanolic extract identified 10 antidiabetic active compounds in the Q. baloot seeds, validating the antihyperglycemic activity. Thus, methanolic crude extract at the doses 150 and 300 mg/kg of Q. baloot showed significant antihyperlipidemic and antihyperglycemic activities, which validate the folkloric utilization of Q. baloot as a remedy in diabetes.
    CONCLUSIONS: In conclusion, the 300 mg/kg methanolic extract of Q. baloot has notable hypoglycemic and hypolipidemic potential, supporting the plant\'s traditional medicinal usage in the treatment of diabetes and its complications. Further studies are needed for the purification, characterization, and structural clarification of bioactive compounds.

    本研究的目的是探索传统加工方法引起的功能成分的显着化学变化,并评估基于9个蒸汽和干燥循环的方法是否可以有效增强黄精根茎的药用效果。对九个加工周期中次生代谢物的动态变化进行了全局分析,并根据次级代谢组初步鉴定了显著差异积累的次级代谢产物。无监督主成分分析(PCA),层次聚类分析(HCA),和次生代谢产物的正交偏最小二乘判别分析(OPLA-DA)清楚地表明,与未加工的粗根茎相比,加工处理显着增加了次生代谢产物在加工后的根茎中的整体积累。前六个加工周期引起功能成分积累的急剧变化,而最后三个没有引起进一步的变化。大多数功能组分的积累在前3次循环后显著增强,6次循环后趋于稳定;同时,前三个周期还导致了许多新组件。然而,在持续6-9个周期的持续处理下,增强效果不可避免地逆转或减弱。此外,继续加工也将少量原始成分的含量降低到无法检测的水平。加工诱导了一些显著丰富的京都基因和基因组百科全书(KEGG)途径,其中前三个处理循环增强了各种次级代谢产物的合成,并显着影响了氨基酸的代谢。总之,这项研究不仅揭示了炮制可以有效增强药用效果,通过两种主要机制,包括增强化学合成和诱导功能成分的结构转化,同时也为优化传统的以蒸、干9个循环为基础的炮制方法,以达到提高海参药效的最佳效果提供了理论指导。
    The aims of this study were to explore the significant chemical changes in functional components induced by the traditional processing method and evaluate whether this method based on nine cycles of steaming and drying can effectively enhance the medicinal effects of Polygonatum cyrtonema rhizome. A global analysis on dynamic changes in secondary metabolites during nine processing cycles was performed, and the significantly differentially accumulated secondary metabolites were initially identified based on the secondary metabolome. Unsupervised principal component analysis (PCA), hierarchical clustering analysis (HCA), and orthogonal partial least squares discriminant analysis (OPLA-DA) on secondary metabolites clearly showed that processing significantly increased the global accumulation of secondary metabolites in processed P. cyrtonema rhizomes compared to unprocessed crude rhizomes. The first six processing cycles induced drastic changes in the accumulation of functional components, while the last three did not induce further changes. The accumulations of most functional components were significantly enhanced after the first three cycles and stabilized after six cycles; meanwhile, the first three cycles also led to numerous new components. However, the enhancing effects were unavoidably reversed or weakened under continued processing lasting 6-9 cycles. Furthermore, continued processing also reduced the contents of a small number of original components to undetectable levels. Processing induced some significantly enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, among which the first three processing cycles enhanced the synthesis of various secondary metabolites and significantly affected the metabolisms of amino acids. In conclusion, this study not only reveals that processing can effectively enhance the medicinal effects, by two main mechanisms including enhancing chemical synthesis and inducing structural transformation of functional components, but also provides theoretical guidance for the optimization of the traditional processing method based on nine cycles of steaming and drying for achieving optimal effects on enhancing the medicinal effects of P. cyrtonema rhizome.

    供应链废物在处置方面带来了重大挑战,使再循环成为从副产品中回收生物活性化合物的有希望和可持续的替代方案。木质纤维素副产品,如STF231,来自药用植物提取物行业,提供有价值的化合物,如多酚和环烯醚萜类,可以通过再循环回收。在一项前所未有的研究中,我们探索和比较了传统的乙醇提取,超声乙醇提取,和天然的低共熔溶剂-超声提取方法在STF231上获得具有抗氧化活性的提取物。使用Folin-Ciocalteu测试测量总多酚(TPC)的提取曲线,并使用FRAP和DPPH测定法测试提取物的抗氧化能力。HPLC-UV用于定量提取物中的酚类和环烯醚萜类标志物。此外,使用绿色分析程序指数(GAPI)评估工艺的可持续性概况,AGREEPREP,和分析性绿色度量方法(AGREE)框架。我们的发现表明,氯化胆碱和乳酸的混合物比例为1:5,在最佳提取条件下,与常规乙醇提取物相比,提取物具有更高的TPC和相似的抗氧化活性。本研究的创新方面在于可持续升级循环协议对先前未经检查的矩阵的潜在应用,产生具有潜在健康应用的提取物。
    Supply chain waste gives rise to significant challenges in terms of disposal, making upcycling a promising and sustainable alternative for the recovery of bioactive compounds from by-products. Lignocellulosic by-products like STF231, which are derived from the medicinal plant extract industry, offer valuable compounds such as polyphenols and iridoids that can be recovered through upcycling. In an unprecedented study, we explored and compared conventional hydroethanolic extraction, ultrasound hydroethanolic extraction, and natural deep eutectic solvents-ultrasound extraction methods on STF231 to obtain extracts with antioxidant activity. The extraction profile of total polyphenols (TPCs) was measured using the Folin-Ciocalteu test and the antioxidant capacity of the extracts was tested with FRAP and DPPH assays. HPLC-UV was employed to quantify the phenolic and iridoid markers in the extracts. Additionally, the sustainability profile of the process was assessed using the green analytical procedure index (GAPI), AGREEprep, and analytical GREEnness metric approach (AGREE) frameworks. Our findings indicate that a choline chloride and lactic acid mixture at a 1:5 ratio, under optimal extraction conditions, resulted in extracts with higher TPC and similar antioxidant activity compared with conventional hydroethanolic extracts. The innovative aspect of this study lies in the potential application of sustainable upcycling protocols to a previously unexamined matrix, resulting in extracts with potential health applications.

    BACKGROUND: Osteoporosis, one of the common bone diseases, manifests itself as a decrease in bone mass. Recently, the use of medicinal plants in the search for effective and low-toxicity therapeutics for the prevention or treatment of osteoporosis has become a trending topic.
    OBJECTIVE: In this study, we aim to prepare a controlled drug carrier system loaded with Gypsophila eriocalyx to determine its potential for anti-osteoporosis applications.
    METHODS: Gypsophila eriocalyx extract (GEE) was prepared, and components were determined. The molecular interactions of the components with Cathepsin K (CatK), which is used as a target in drug development against osteoporosis, were revealed by in silico molecular docking and MD methods. ADMET profiles were also examined. GEE-loaded chitosan nanoparticles (CNPs) were synthesized. The nanoparticles\' morphology, encapsulation efficiency, loading capacity, release profile, average size, polydispersity index, and zeta potentials were determined. The cytotoxic effects of GEE and GEE-loaded CNPs on the L929 and osteogenic proliferation profiles on human bone marrow stem cells (hBMC) were examined.
    RESULTS: The MD analysis revealed no breaks or atomic changes in the dynamic system, and the docking analysis confirmed the continued interaction of identical residues. It was determined that the GEE-loaded CNP formulation was produced successfully, had no toxic effect on the L929, and had an osteogenic proliferation effect on hBMC.
    CONCLUSIONS: In line with the in vitro and in silico results obtained, it was evaluated that GEE-loaded CNPs can be used as a controlled drug release system as a candidate formulation with phytotherapeutic properties for osteoporosis treatment.q1.

    在植物组织内渐近存活的细菌被称为内生菌。由于与植物宿主的密切关系,它们作为植物生长促进剂的应用一直是人们感兴趣的问题。Meliaazedarach是一种广泛分布的药用树,具有良好的杀虫效果,抗菌,和抗病毒活性。这项研究的目的是分离和表征从M.azedarach内生细菌,并分析其促进植物生长的活性,作为生物制品的潜在应用。细菌是从阿根廷东北部两个地方生长的树木的根和叶子中分离出来的。通过重复基因外回文序列PCR和16SrDNA序列分析对分离株进行了表征。在体外测定了植物的促生长活性,对选定的分离株的植物生长的改善在M.azedarach小植株上进行了测试,并在盐胁迫条件下测试了选定的产生ACC脱氨酶的分离株对番茄幼苗的影响。从根中获得最高的内生细菌丰度和多样性。所有分离株都具有至少一种测定的植物生长促进活性,其中80%具有拮抗活性。最有效的细菌是蒙氏假单胞菌,法森假单胞菌,Burkholderiasp.和Cupriavidussp.用于磷酸盐溶解(2064μgPml-1),IAA产量(94.7μgml-1),铁载体生产指数(5.5)和ACC脱氨酶活性(1294nmolα-酮丁酸酯mg-1h-1)。M.azedarach接种试验揭示了细菌生长促进潜力,蒙氏假单胞菌,法氏假单胞菌和库雷韦斯菌。突出它们对叶面积的影响,叶片干重,比叶面积,和总Chl,Mg和N含量,增长率高达149%,58%,65%,178%,76%和97.7%,分别,与NI植物相比。产生ACC脱氨酶的高效分离株在盐水条件下增加了番茄植物的胁迫耐受性。总的来说,这些发现表明了内生植物分离株作为生物刺激剂和生物防治剂的潜力。
    Bacteria that live asymptomatically within plant tissues are known as endophytes. Because of the close relation with the plant host, they have been a matter of interest for application as plant growth promoters. Melia azedarach is a widely distributed medicinal tree with proven insecticidal, antimicrobial, and antiviral activity. The aim of this study was to isolate and characterize endophytic bacteria from M. azedarach and analyze their plant growth promoting activities for the potential application as biological products. Bacteria were isolated from roots and leaves of trees growing in two locations of Northeastern Argentina. The isolates were characterized by repetitive extragenic palindromic sequence PCR and 16S rDNA sequence analysis. The plant growth-promoting activities were assayed in vitro, improvement of plant growth of selected isolates was tested on M. azedarach plantlets, and the effect of selected ACC deaminase producing isolates was tested on tomato seedlings under salt-stress conditions. The highest endophytic bacterial abundance and diversity were obtained from the roots. All isolates had at least one of the assayed plant growth-promoting activities and 80 % of them had antagonistic activity. The most efficient bacteria were Pseudomonas monteilii, Pseudomonas farsensis, Burkholderia sp. and Cupriavidus sp. for phosphate solubilization (2064 μg P ml-1), IAA production (94.7 μg ml-1), siderophore production index (5.5) and ACC deaminase activity (1294 nmol α-ketobutyrate mg-1 h-1). M. azedarach inoculation assays revealed the bacterial growth promotion potential, with Pseudomonas monteilii, Pseudomonas farsensis and Cupriavidus sp. standing out for their effect on leaf area, leaf dry weight, specific leaf area, and total Chl, Mg and N content, with increases of up to 149 %, 58 %, 65 %, 178 %, 76 % and 97.7 %, respectively, compared to NI plants. Efficient ACC deaminase-producing isolates increased stress tolerance of tomato plants under saline condition. Overall, these findings indicate the potential of the endophytic isolates as biostimulant and biocontrol agents.

    常规的治疗剂不再足以对抗利什曼病。这种复杂的情况继续具有高死亡率和公共卫生影响。本研究旨在探索一系列广泛的实验来监测6-shogaol的生物活性,生姜的主要成分,和锑酸葡甲胺(MA或Gluantime®)。6-shogaol与诱导型一氧化氮合酶(iNOS)的结合亲和力,从L-精氨酸中催化一氧化氮(NO)的主要酶是对接概述的来源。6-shogaol的抑制作用,MA,和混合物使用比色和巨噬细胞测定法进行评估。通过紫外可见分光光度法推断抗氧化活性。通过可定量的实时聚合酶链反应测量可变表达的基因。通过流式细胞术分析凋亡和细胞周期谱。此外,通过电泳进行DNA片段化测定,抗氧化代谢产物包括超氧化物歧化酶(SOD),过氧化氢酶(CAT),以及通过酶联免疫吸附测定的一氧化氮(NO)。6-shogaol和MA表现出多种协同作用机制。这些包括显著的利什曼杀菌作用,有效的抗氧化活性,安全指数高,M1巨噬细胞/Th1相关细胞因子的上调(包括,γ-干扰素,白细胞介素-12p40,肿瘤坏死因子-α,和相关的iNOS),在亚G0/G1期明显的细胞分裂捕获,通过核成分的DNA片段化的高凋亡率。此外,经处理的细胞内amastigotes显著提高了NO的活性,而SOD和CAT活性显著降低。这项研究是排他性的,因为以前没有进行过类似的调查。这些全面的机械动作为额外的高级学习奠定了逻辑基础。
    Conventional therapeutic agents are no longer adequate against leishmaniasis. This complex condition continues to have a high mortality rate and public health impact. The present study aimed to explore an extensive array of experiments to monitor the biological activities of 6-shogaol, a major component of ginger, and meglumine antimoniate (MA or Glucantime®). The binding affinity of 6-shogaol and inducible nitric oxide synthase (iNOS), a major enzyme catalyzing nitric oxide (NO) from L-arginine was the source for the docking outline. The inhibitory effects of 6-shogaol, MA, and mixture were assessed using colorimetric and macrophage assays. Antioxidant activity was inferred by UV-visible spectrophotometry. Variably expressed genes were measured by quantifiable real-time polymerase chain reaction. Apoptotic and cell cycle profiles were analyzed by flow cytometry. Moreover, a DNA fragmentation assay was performed by electrophoresis and antioxidant metabolites include superoxide dismutase (SOD), catalase (CAT), and also nitric oxide (NO) by enzyme-linked immunosorbent assay. 6-shogaol and MA exhibited multiple synergistic mechanisms of action. These included a remarkable leishmanicidal effect, potent antioxidative activity, a high safety index, upregulation of M1 macrophages/Th1-associated cytokines (including, γ-interferon, interleukin-12p40, tumor necrotizing factor-alpha, and associated iNOS), significant cell division capture at the sub-G0/G1 phase, a high profile of apoptosis through DNA fragmentation of the nuclear components. In addition, the activity of NO was substantially elevated by treated intracellular amastigotes, while SOD and CAT activities were significantly diminished. This study is exclusive because no similar investigation has inclusively been conducted before. These comprehensive mechanistic actions form a logical foundation for additional advanced study.

    背景:基于药用植物的漱口水已证明在控制斑块和炎症方面有益处,积极作用于牙龈炎患者的口腔卫生。在传统医学中,石榴已在欧洲国家用于治疗口腔疾病,亚洲,北美,和非洲。
    目的:本研究旨在对石榴治疗牙龈炎的牙科应用进行全面综述。包括种族医学用途,随机临床试验分析,对牙龈卟啉单胞菌的抗菌活性,从这种植物中分离出的植物化学物质的作用机制,和临床前毒性。
    方法:文献来自GoogleScholar,PubMed®,SciELO,和ScienceDirect®,自2001年发布关于该主题的第一份报告以来,直到2024年3月。
    结果:一些临床试验表明,含有石榴的漱口水在治疗牙龈炎患者方面具有与氯己定相同或更好的疗效,确认传统社区使用这种植物的迹象。然而,有关该植物果实提取物的体外抗菌活性的报道尚未显示出对病原体牙龈卟啉单胞菌的临床相关性。从石榴中分离出的ellagitanninpunicalagin已显示出对几种革兰氏阳性和革兰氏阴性细菌菌株的潜力,但是,到目前为止,该化合物尚未对牙龈卟啉单胞菌进行过测试。很可能是类黄酮的作用机制,比如槲皮素,参与抑制RgpA的活性,RgpB,和牙龈卟啉单胞菌的Kgp蛋白酶。
    结论:总之,从石榴获得的天然产品没有毒副作用,可以被认为是推荐用于治疗牙龈炎和其他口腔疾病的商业产品的可能替代品。
    BACKGROUND: Mouthwashes based on medicinal plants have demonstrated benefits in controlling plaque and inflammation, acting positively on the oral hygiene of patients with gingivitis. In traditional medicine, Punica granatum L. has been used to treat oral diseases in countries in Europe, Asia, North America, and Africa.
    OBJECTIVE: The present study aimed to conduct a comprehensive review on the dental applications of Punica granatum L. for the treatment of gingivitis, including ethnomedicinal uses, analysis of randomized clinical trials, antibacterial activity against Porphyromonas gingivalis, mechanisms of action of phytochemicals isolated from this plant, and preclinical toxicity.
    METHODS: The literature was retrieved from Google Scholar, PubMed®, SciELO, and ScienceDirect®, since the first report published on the topic in 2001 until March 2024.
    RESULTS: Several clinical trials have demonstrated that mouthwashes containing P. granatum have equal or better efficacy than chlorhexidine in treating patients with gingivitis, confirming the indications for use of this plant by traditional communities. However, reports on the in vitro antibacterial activity of extracts from the fruits of this plant have not shown clinical relevance against the pathogen P. gingivalis. The ellagitannin punicalagin isolated from P. granatum has shown potential against several strains of Gram-positive and Gram-negative bacteria, but, to date, this compound has not yet been tested against P. gingivalis. It is likely that the mechanisms of action of flavonoids, such as quercetin, are involved in the inhibition of the activities of the RgpA, RgpB, and Kgp proteases of P. gingivalis.
    CONCLUSIONS: In summary, natural products obtained from P. granatum do not present toxic side effects and can be considered as possible substitutes of commercial products recommended for the treatment of gingivitis and other oral diseases.
