Japanese pickled apricot, called \"umeboshi\", is a traditional food that has experientially been consumed as a folk medicine. The main variation of umeboshi is called \"shiso-zuke umeboshi\", meaning pickled with red perilla leaves to add a colorful appearance. This study investigated changes in phenolics and antioxidant potential of shiso-zuke umeboshi during pickling processes and simulated digestion. Results showed that the red perilla pickling (PP; 1338.12) had 13 times higher phenolics than salt pickling (SP; 101.99) in μg/g DW, and the formation of rosmarinic acid was enhanced. The simulated digestion showed a gradual increase in antioxidant content and activity from the stomach to small intestine, with TPC and TFC being rapidly released in the intestinal environment. The study concluded that shiso-zuke umeboshi provides higher health benefits due to the excellent antioxidant compounds produced through the perilla pickling process.

This study analyzed the effects of benzoic acid (BA) on the physicochemical properties and microbial community structure of perilla rhizosphere soil. The analysis was based on high-throughput sequencing technology and physiological and biochemical detection. The results showed that with the increase in BA concentration, soil pH significantly decreased, while the contents of total nitrogen (TN), alkaline nitrogen (AN), available phosphorus (AP), and available potassium (AK) significantly increased. The activities of soil conversion enzymes urease and phosphatase significantly increased, but the activities of catalase and peroxidase significantly decreased. This indicates that BA can increase soil enzyme activity and improve nutrient conversion; the addition of BA significantly altered the composition and diversity of soil bacterial and fungal communities. The relative abundance of beneficial bacteria such as Gemmatimonas, Pseudolabrys, and Bradyrhizobium decreased significantly, while the relative abundance of harmful fungi such as Pseudogymnoascus, Pseudoeurotium, and Talaromyces increased significantly. Correlation analysis shows that AP, AN, and TN are the main physicochemical factors affecting the structure of soil microbial communities. This study elucidates the effects of BA on the physicochemical properties and microbial community structure of perilla soil, and preliminarily reveals the mechanism of its allelopathic effect on the growth of perilla.

Intercropping systems can improve soil fertility and health, however, soil microbial communities and functional genes related to carbon, nitrogen and phosphorus cycling under the intercropping system of mesquite and perilla have not been studied. Therefore, in the present study, different planting densities and varieties of Perilla frutescens (L.) Britt and kiwifruit were used for intercropping, and changes in soil microbial communities and carbon, nitrogen, and phosphorus cycling genes in kiwifruit inter-roots under inter-cropping conditions were investigated by macro-genome sequencing technology. The results showed that intercropping with Perill caused a decrease in most soil nutrients, soil enzyme activities, and had a significant impact on the microbial (bacteria and fungi) diversity. Inter-cropping increased the relative abundance of the dominant bacterial phylum \"Proteobacteria\" and \"Actinobacteria\" by 47 and 57%, respectively, but decreased the relative abundance of the dominant fungal phylum \"Chordata\" and \"Streptophyta\" by 11 and 20%, respectively, in the inter-root soil of kiwifruit, and had a significant impact on the microbial (bacteria and fungi) diversity. In addition, inter-cropping could greatly increase the inter-root soil carbon sequestration (PccA, korA/B/C/D, fhs, and rbcl/s), carbon degradation (abfD), organic nitrogen mineralization (GDH2), denitrification (napA/B, nirB, norB), organic phosphorus mineralization (phop, phn), and inorganic phosphorus solubilization (gcd, ppk) gene abundance. The gene co-occurrence network indicated that soil korB, nirB, and gnd key functional genes for carbon, nitrogen, and phosphorus cycling in kiwifruit inter-root soils and their expression was up-regulated in the inter-cropping group. Structural equation (SEM) further showed that soil total nitrogen, organic matter, total carbon and acid phosphatase had significant effects on microbial diversity (p < 0.05) and soil carbon cycling gene korB and phosphorus cycling gene purH (p < 0.001), while korB and purH had positive effects on kiwifruit quality. In conclusion, intercropping perilla in kiwifruit orchards changed the structure of bacterial and fungal communities in the inter-root soil of kiwifruit, but I believe that intercropping perilla stimulates carbon degradation, leading to carbon emission and serious loss of soil nutrients, and that prolonged intercropping may adversely affect the quality of kiwifruit, and thus its limitations should be noted in future studies.

The effects and reasons of perilla juice (PJ) and ginger juice (GJ) on the reduction of \"warmed-over flavor\" (WOF) in surimi gels were revealed by detecting odor profiles and protein and lipid oxidation degrees of surimi gels, concentrations and odor activity values (OAVs) of WOF compounds. Adding PJ and GJ to surimi gels significantly reduced the WOF and improved the fish fragrance odor, but sodium ascorbate (SA) only weakened the WOF. The (E,E)-2,4-heptadienal\'s OAVs in the PJ and GJ groups were decreased by >50% compared with the control check (CK) and SA groups. Meanwhile, surimi gels added with PJ and GJ presented lower lipid and protein oxidation degrees. The verification test indicated that PJ and GJ\'s aroma had a masking effect on the WOF. In conclusion, PJ and GJ reduced the WOF in surimi gels by preventing WOF compounds\' production and masking the WOF with their distinct aroma.

Obtaining a robust phylogeny proves challenging due to the intricate evolutionary history of species, where processes such as hybridization and incomplete lineage sorting can introduce conflicting signals, thereby complicating phylogenetic inference. In this study, we conducted comprehensive sampling of Elsholtzieae, with a particular focus on its largest genus, Elsholtzia. We utilized 503 nuclear loci and complete plastome sequences obtained from 99 whole-genome sequencing datasets to elucidate the interspecific relationships within the Elsholtzieae. Additionally, we explored various sources of conflicts between gene trees and species trees. Fully supported backbone phylogenies were recovered, and the monophyly of Elsholtzia and Keiskea was not supported. Significant gene tree heterogeneity was observed at numerous nodes, particularly regarding the placement of Vuhuangia and the E. densa clade. Further investigations into potential causes of this discordance revealed that incomplete lineage sorting (ILS), coupled with hybridization events, has given rise to substantial gene tree discordance. Several species, represented by multiple samples, exhibited a closer association with geographical distribution rather than following a strictly monophyletic pattern in plastid trees, suggesting chloroplast capture within Elsholtzieae and providing evidence of hybridization. In conclusion, this study provides phylogenomic insights to untangle taxonomic problems in the tribe Elsholtzieae, especially the genus Elsholtzia.

An excessive inflammatory response of the gastrointestinal tract is recognized as one of the major contributors to ulcerative colitis (UC). Despite this, effective preventive approaches for UC remain limited. Rosmarinic acid (RA), an enriched fraction from Perilla frutescens, has been shown to exert beneficial effects on disease-related inflammatory disorders. However, RA-enriched perilla seed meal (RAPSM) and perilla seed (RAPS) extracts have not been investigated in dextran sulfate sodium (DSS)-induced UC in mice. RAPSM and RAPS were extracted using the solvent-partitioning method and analyzed with high-pressure liquid chromatography (HPLC). Mice with UC induced using 2.5% DSS for 7 days were pretreated with RAPSM and RAPS (50, 250, 500 mg/kg). Then, the clinical manifestation, colonic histopathology, and serum proinflammatory cytokines were determined. Indeed, DSS-induced UC mice exhibited colonic pathological defects including an impaired colon structure, colon length shortening, and increased serum proinflammatory cytokines. However, RAPSM and RAPS had a protective effect at all doses by attenuating colonic pathology in DSS-induced UC mice, potentially through the suppression of proinflammatory cytokines. Concentrations of 50 mg/kg of RAPSM and RAPS were sufficient to achieve a beneficial effect in UC mice. This suggests that RAPSM and RAPS have a preventive effect against DSS-induced UC, potentially through alleviating inflammatory responses and relieving severe inflammation in the colon.

Microplastics (MPs) and copper (Cu) pollution coexist widely in cultivation environment. In this paper, polyvinyl chloride (PVC) were used to simulate the MPs exposure environment, and the combined effects of MPs + Cu on the germination of perilla seeds were analyzed. The results showed that low concentrations of Cu promoted seed germination, while medium to high concentrations exhibited inhibition and deteriorated the morphology of germinated seeds. The germination potential, germination index and vitality index of 8 mg • L-1 Cu treatment group with were 23.08%, 76.32% and 65.65%, respectively, of the control group. The addition of low concentration PVC increased the above indicators by 1.27, 1.15, and 1.35 times, respectively, while high concentration addition led to a decrease of 65.38%, 82.5%, and 66.44%, respectively. The addition of low concentration PVC reduced the amount of PVC attached to radicle. There was no significant change in germination rate. PVC treatment alone had no significant effect on germination. MPs + Cu inhibited seed germination, which was mainly reflected in the deterioration of seed morphology. Cu significantly enhanced antioxidant enzyme activity, increased reactive oxygen species (ROS) and MDA content. The addition of low concentration PVC enhanced SOD activity, reduced MDA and H2O2 content. The SOD activity of the Cu2+8 + PVC10 group was 4.05 and 1.35 times higher than that of the control group and Cu treatment group at their peak, respectively. At this time, the CAT activity of the Cu2+8 + PVC5000 group increased by 2.66 and 1.42 times, and the H2O2 content was 2.02 times higher than the control. Most of the above indicators reached their peak at 24 h. The activity of α-amylase was inhibited by different treatments, but β-amylase activity, starch and soluble sugar content did not change regularly. The research results can provide new ideas for evaluating the impact of MPs + Cu combined pollution on perilla and its potential ecological risk.

This study investigates the effect of supplementation of Perilla seeds (PS) on the performance, egg quality, blood biochemical parameters, and egg yolk fatty acids composition in the diet of egg-laying chicken. A total of 1600 Lohmann laying hens were randomly assigned to four different groups with 4 replicates each (100 chickens/replicate) and were subjected to varying PS concentrations (PS0, PS6, PS12, and PS18; 0%, 6%, 12%, and 18%, respectively) for four weeks, including an acclimation period of one week. The results showed no significant differences among the groups for average egg weight (P > 0.005). The laying rate (%), feed conversion ratio (FCR) and average feed intake (AFI) decreased significantly for birds fed on 18% PS as compared to the other treatments (P < 0.005). Haugh unit, albumin height, egg-shape index and eggshell thickness among hens fed PS diets were greater averaging 80.53, 7.00, 1.29, 0.34 compared to 76.84, 6.86, 1.25 and 0.32 from Control hen eggs (P < 0.05). Serum analysis showed a trend towards elevated levels of glucose (Glu), total protein (TP) and aspartate aminotransferase (AST) among treatments. Total cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) decreased for the birds fed on 6% PS. The fatty acid composition of egg yolk showed a substantial reduction for α-linolenic acid and docosahexaenoic acid increased significantly by the incorporating PS in the diet (P < 0.001). PS incorporation in diets resulted in significant improvements in both performance indicators and greater amounts of α-linolenic acid and DHA in egg yolks. These findings indicate that PS at 6% inclusion has the potential to improve fatty acid profiles of egg yolk without any adverse effect on performance of egg quality.

Perilla frutescens var. crispa \'Antisperill\' has stronger anti-inflammatory effects than the original cultivar (red perilla), but studies on its bioactive compounds are limited. This study aimed to evaluate the antioxidant compounds and activity of red perilla and \'Antisperill\', as well as their processed products using freeze drying (FD) and microwave-assisted low temperature vacuum drying (MVD). Red perilla had higher antioxidant compounds and activities than \'Antisperill\'. MVD showed significantly greater antioxidant properties than FD among the processed products. Isoegomaketone, studied for its anti-obesity, antioxidant, anti-inflammatory, and anticancer properties, was only found in \'Antisperill\' and its processed products, with the highest content in \'Antisperill\' MVD samples. This study highlights that \'Antisperill\' contains various antioxidants, and MVD is the optimal drying method to preserve and enhance its antioxidant content. As a result, \'Antisperill\' could potentially serve as a natural antioxidant with both anti-inflammatory and antioxidant functions.
