    目前,一个明确的兴趣已经给了浆果由于其丰富的活性代谢产物,包括花青素和无色酚类。因此,本工作的主要目的是研究酚醛的概况,抗氧化能力,来自消费者高度赞赏的三种红色水果的富含酚类提取物对正常人真皮成纤维细胞(NHDF)和人结肠癌细胞系(Caco-2)细胞的抗增殖作用:两种黑莓(Rubusfruticosus和Rubusulmifolius)和一种桑树(Morusnigra)。通过HPLC-DAD-ESI/MSn和HPLC-DAD鉴定并定量了19种不同的酚类物质,分别。专注于富含酚类提取物的生物潜力,他们都表现出明显的清除能力。关于抗增殖特性,与NHDF细胞相比,fruticosusR.表现出对Caco-2细胞的细胞毒性选择性。为了更深入地探索生物潜力,还进行了与阳性对照(抗坏血酸和5-氟尿嘧啶)的组合。最后,获得的数据是另一个证据,表明天然植物富含酚类的提取物与阳性对照的组合可以降低临床治疗成本和化学药物可能的毒性.
    Currently, a clear interest has been given to berries due to their richness in active metabolites, including anthocyanins and non-coloured phenolics. Therefore, the main aim of the present work is to investigate the phenolic profile, antioxidant abilities, and antiproliferative effects on normal human dermal fibroblasts (NHDF) and human colon carcinoma cell line (Caco-2) cells of phenolic-rich extracts from three red fruits highly appreciated by consumers: two species of blackberries (Rubus fruticosus and Rubus ulmifolius) and one species of mulberry (Morus nigra). A total of 19 different phenolics were identified and quantified by HPLC-DAD-ESI/MSn and HPLC-DAD, respectively. Focusing on the biological potential of the phenolic-rich extracts, all of them revealed notable scavenging abilities. Concerning the antiproliferative properties, R. fruticosus presented a cytotoxic selectivity for Caco-2 cells compared to NHDF cells. To deeper explore the biological potential, combinations with positive controls (ascorbic acid and 5-fluorouracil) were also conducted. Finally, the obtained data are another piece of evidence that the combination of phenolic-rich extracts from natural plants with positive controls may reduce clinical therapy costs and the possible toxicity of chemical drugs.

    <b>背景和目的:</b>胆汁淤积是胆汁流动受限或阻塞时发生的肝脏疾病。雌激素诱导的胆汁淤积的标志是胆汁流量减少和胆汁酸在肝脏中的积累以及肝脏损伤。目的是评估蔓越莓水提取物(CWE)对EE诱导的大鼠胆汁淤积的肝保护作用。<b>材料和方法:</b>将体重约150±10g的成年白化病大鼠分为六组,每组六只动物。作为对照组,三组(I,II和IV)和三个实验组(III,V,VI).<b>结果:</b>口服CWE15天(150mgkg<sup>1</sup>b.wt.)在EE处理的大鼠中(100μgkg<sup>1</sup>5天b.wt.)改善血清胆固醇,胆汁酸和TBIL以及肝脏SOD和GPx显着。此外,CWE抑制了ALP,ALT,γ-GT活性以及TNF-α水平,NO,与EE处理大鼠相比,MMP-2和MMP-9和MDA。另一方面,与EE处理的大鼠相比,蔓越莓提取物组大鼠肝脏TLR4,NF-κB和p38MAPK基因表达下调。CWE的预防性作用II比预防性作用更明显。肝组织的组织病理学检查也支持了蔓越莓在恢复正常肝功能能力方面的保肝作用。<b>结论:</b>结果表明,蔓越莓提取物通过使TLR4、NF-κB和p38MAPK基因表达水平正常化,对EE诱导的胆汁淤积有较强的预防作用。
    <b>Background and Objective:</b> Cholestasis is a liver disease that occurs when bile flow is restricted or blocked. Estrogen-induced cholestasis is marked by a reduction in bile flow and the accumulation of bile acids in the liver as well as liver damage. The aim was to evaluate the hepatoprotective effect on EE-induced cholestasis in rats of Cranberry Water Extract (CWE). <b>Materials and Methods:</b> Adult albino rats weighing approximately 150±10 g were divided into six groups of six animals each. As control groups, three groups (I, II and IV) and three experimental groups were used (III, V, VI). <b>Results:</b> Oral administration for 15 days of CWE (150 mg kg<sup>1</sup> b.wt.) in EE-treated rats (100 μg kg<sup>1</sup> 5 days b.wt.) improved serum cholesterol, bile acid and TBIL as well as hepatic SOD and GPx significantly. Also, CWE inhibited ALP, ALT, γ-GT activity as well as levels of TNF-α, NO, MMP-2 and MMP-9 and MDA in comparison with the EE treatment rats. On the other hand, the liver TLR4, NF-κB and p38MAPK gene expression was down regulated group of rats administrated with cranberry extract when compared with the EE-treated rats. CWE\'s prophylactic action II is more pronounced than prophylactic one. The hepatoprotective effects of cranberry in restoring normal liver functional ability were also supported by histopathological examination of liver tissues. <b>Conclusion:</b> The results show clearly that cranberry extract has a strong prophylactic effect in EE-induced cholestasis by normalizing the levels of TLR4, NF-κB and p38MAPK gene expression.

    High-frequency bud break and multiple shoots were induced in apical shoot buds and nodal explants ofMorus cathayana, M. lhou andM. serrata on Murashige and Skoog (MS) medium containing 0.5-1.0 mg/l 6-benzylaminopurine (BAP). Addition of gibberellic acid (0.4 mg/l) along with BAP induced faster bud break both in apical shoot buds and nodal explants and also enhanced the frequency of bud break in all three species. Shoot culture initiation was greatly influenced by explant type, explant age and explanting season. The shoots were successfully rooted on half-strength MS medium containing a combination of indole-3-acetic acid, indole-3-butyric acid and indole-3-propionic acid, each at 1.0 mg/l. The plantlets were successfully acclimated and eventually established in soil.

    Benzofuran heterocycles are fundamental structural units in a variety of biologically active natural products as well as synthetic materials. Over the time, benzofuran derivatives have attracted many researchers due to the broad scope of their biological activity, which include anticancer, antimicrobial, immunomodulatory, antioxidant and anti-inflammatory properties. Egonol, homoegonol and moracin families are biologically active natural products containing benzofuran heterocycle as basic structural units. This paper focuses on the moracin family (moracin A to Z). Morus, a genus of flowering plants in the family Moraceae, comprises 10-16 species of deciduous trees commonly known as mulberries. The root bark, stem bark and leaves of Morus alba, M. lhou, Morus macroura are the main sources for arylbenzofuran derivatives including the moracins. A large volume of research has been carried out on moracins and their derivatives, which has shown the pharmacological importance of this benzofuran heterocyclic nucleus. In this mini-review, we attempt to highlight the importance of moracins, as they have been a major source for drug development. Herein, we also summarize the current state of the art concerning the synthesis and medicinal use of moracins A-Z.
