Pearson correlation analysis indicated that the impact of soil mineral elements on the levels of stilbene glycosides is greater compared to that on anthraquinones. A negative correlation was observed between the levels of elements Na, Zn, Ba, Ti, and 2,3,5,4′-tetrahydroxysilbene 2-O-glucoside (THSG-1). Conversely, a positive correlation was found between the contents of elements Na, Ce, Ti, and physcion and THSG-5, 2 components that exhibited higher levels in Deqing.

Atractylodis Macrocephalae Rhizoma (BZ) is known for strengthening the spleen and harmonizing the stomach. BZ processed with Aurantii Fructus Immaturus juice (ZSZBZ), a classic decoction since the Han Dynasty, can enhance the efficacy of BZ. However, the key active components and targets of action of ZSZBZ remain undiscovered. Aim of the study This study aimed to investigate the bioactive chemical constituents of ZSZBZ against AGU and their possible mechanisms of action, elucidating the scientific content of ZSZBZ processing. Materials and methods Initially, we examined rat stomach histopathology and conducted ELISA for oxidative stress and inflammation. Subsequently, we investigated underlying mechanisms using metabolomics. Further analysis of potent components and key targets in ZSZBZ was conducted through liquid chromatography-mass spectrometry analysis combined with network pharmacology. Finally, key targets were analyzed by Western blot. Results ZSZBZ improved gastric histopathology, reversing high alcohol-induced oxidative stress (SOD, CAT) and inflammatory level (TNF-α, IL-6) disorders. This is associated with ZSZBZ’s regulation of amino acid metabolism, energy metabolism, and inflammatory response-related metabolic pathways, along with key targets PTGS2, MAPK1, and KDR. The significant increase in potency of ZSZBZ may be attributed to elevated levels of naringenin, hesperidin, hesperidin, and rhamnoceroside after concoction. Conclusions Combining metabolomics and network pharmacology, this study elucidated that ZSZBZ enhanced gastroprotection by modulating amino acid metabolism, antioxidant, and inflammation-related targets and pathways, providing insights into the bioactive compounds and potential mechanisms of herbal concoctions.","PeriodicalId":503277,"journal":{"name":"Science of Traditional Chinese Medicine","volume":"3 3","pages":"121 - 137"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141392633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employed ultra-performance liquid chromatography–quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS) and pattern analysis to compare the terpenoids between AR and SAR. Additionally, this study compared the effects of AR and SAR on the gene expression in the kidneys of the rat model of edema (syndrome of kidney Yin deficiency) by transcriptomics to decipher the mechanism of salt processing. Materials and methods AR and SAR were extracted by ultrasonication, and data were collected by UPLC-Q-TOF-MS in the positive ion mode. Transcriptome sequencing was employed to determine the gene expression levels of the rat model treated with AR and SAR, and the differentially expressed genes (DEGs) were obtained. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment was performed for the DEGs. The protein-protein interaction (PPI) network was built, on the basis of which the core targets were screened out. Finally, real-time quantitative polymerase chain reaction (RT-PCR) was conducted to verify the core targets. Results A total of 63 terpenoids were detected in AR and SAR, and salt processing had a significant effect on the content of terpenoids. AR and SAR mainly participated in the regulation of inflammation and immune responses, and SAR regulated more DEGs than AR. Additionally, SAR exerted more extensive regulatory effects on the targets than AR. Conclusion Salt processing mainly changes the content of chemical compounds in AR, which may indirectly optimize the proportion of the main compounds to enhance the therapeutic effect while reducing the toxicity. AR and SAR mainly ameliorate the edema due to kidney Yin deficiency by reducing inflammation and improving immunity.

Method We interviewed the local stakeholders and e-commerce platforms in Oroqen Autonomous Banner and Morin Dawa Daur Autonomous Banner regarding the origin, circulation, distribution, and prices of different medicinal parts of P. frutescens. In addition, the maximum entropy model was used to predict the potential distribution of P. frutescens in the study area. According to the Chinese Pharmacopeia (2020 edition), we measured the content of index components in the collected Perillae Folium, Perillae Caulis, and Perillae Fructus samples and evaluated the quality of the samples by quantitative and cluster analyses. Remote sensing was employed to distinguish and calculate the P. frutescens area in highly suitable regions. The autoregressive integrated moving average model was adopted to analyze the Perillae Fructus price in the study area. Result The results showed 8 value chains for P. frutescens. The cooperation chain between farmers and enterprises in the study area could maximize the benefits for all stakeholders and guarantee the quality of the medicinal materials. The results of the regionalization analysis showed that the most suitable area for planting P. frutescens was the junction between Oroqen Autonomous Banner and Morin Dawa Daur Autonomous Banner. Chemical results showed that Perillae Fructus and Perillae Caulis samples were unqualified and mostly purchased from e-commerce platforms. We identified 5 land types, among which the cultivated land area was 3247.7501 km2. The price of Perillae Fructus in the study area showed a rising trend, although this trend slowed down. Conclusion This study involved various links in the production and circulation of medicinal materials from planting to consumption by consumers, which can help to facilitate the future research on any link.

Bakuchiol, as one of the main active ingredients from the seeds of Psoralea corylifolia L, displays whitening, antioxidant, antiaging, and free radical-scavenging activities and attracts wide attention especially in the cosmetics industry. However, environmentally friendly extraction technologies with high efficiency and high product purity remain to be developed for the scale production of bakuchiol. In this study, a new approach (acetic acid–steaming–assisted technique) was developed to improve the extraction efficiency of bakuchiol. The factors influencing the extraction efficiency of bakuchiol, including seed powder granularity, acetic acid volume, temperature, and time, were optimized based on single-factor experiments. The extraction conditions were optimized as steaming the seed powder (100 g) of 40–100 meshes with acetic acid (50 mL) for 10 minutes, from which a crude extract (25.1 g) containing bakuchiol was obtained. High purity (99.1) of bakuchiol (6.02 g) was then prepared by silica gel column chromatography in a one-step process. The method established in this study had higher extraction rate than other methods. The antioxidant potential of bakuchiol was evaluated based on the ABTS free radical scavenging activity and ferric reducing antioxidant power.

It is rich in resistant starch (RS), which imparts various beneficial effects, including anticonstipation, regulation of blood lipids, and prevention of gastric ulcers. However, the resistance of native yam starch to digestion diminishes during cooking, necessitating suitable modifications. In this article, yam starch was complexed with five different polyphenols to create RS5. The goal was to explore how these diverse polyphenols influence the physicochemical characteristics and bioactivities associated with yam RS. Yam starch-polyphenol complexes, involving five different polyphenols, namely, magnolol (MAG), ferulic acid (FA), resveratrol (RES), apple polyphenols (APs), and green tea polyphenols (GTPs), were prepared. The investigation encompassed the assessment of physicochemical properties, structural traits, in vitro cholate binding capacity, and in vitro antidigestive effects of these complexes. The results highlight the pronounced affinity of MAG for yam starch, followed by FA. Fourier transform infrared spectroscopy reveals that starch-polyphenol binding primarily involves noncovalent interactions. X-ray diffraction analysis discloses V-type crystal structures in YS-MAG, YS-APs, and YS-GTPs complexes. The incorporation of polyphenols reduces the thermal stability of starch while enhancing its in vitro cholate binding capacity, restraining starch digestion, and elevating RS content. Notably, YS-FA exhibits an impressive RS content of up to 54.15%. In addition, YS-MAG and YS-FA significantly enhance the production of short-chain fatty acids. These findings deepen our comprehension of the interplay between yam starch and polyphenols, offering valuable insights for the development of novel food products with enhanced health benefits.","PeriodicalId":503277,"journal":{"name":"Science of Traditional Chinese Medicine","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139208204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
