Clinically utilized for managing rheumatoid arthritis and other rheumatic conditions, its documented efficacy includes promoting blood circulation, resolving stasis, reducing swelling, alleviating pain, and facilitating bone healing. However, the ambiguous material basis of HuoXueJieGu decoction significantly impedes the advancement of its quality control protocols and in‐depth exploration of its underlying pharmacological mechanisms. To address this gap, a comprehensive analytical method was developed for the systematic characterization of the HuoXueJieGu decoction aqueous extract. This method utilized a gradient elution system with ACN and an aqueous solution of 0.1% formic acid as the mobile phase. A total of 143 compounds were identified in the HuoXueJieGu decoction aqueous extract in vitro, which were categorized as follows: 31 organic acids, 29 flavonoids, 15 amino acids, 14 phenylpropanoids, 14 phenols, 12 alkaloids, 11 sugars and glycosides, 8 terpenoids, and 9 others. Furthermore, 31 constituents were detected in the plasma, indicating their systemic absorption. Tissue distribution analysis revealed the presence of 24, 19, 23, 40, and 38 prototype compounds in the heart, liver, spleen, lung, and kidney, respectively. Furthermore, this study represents the first report on the systematic and rapid characterization of the chemical profile of HuoXueJieGu decoction. It is also the first to interpret the functional roles of its constituents within the framework of the traditional “monarch‐minister‐assistant‐guide” theory. These findings provide a crucial scientific basis for elucidating the material basis of its efficacy and for advancing its quality control standards.","PeriodicalId":21639,"journal":{"name":"SEPARATION SCIENCE PLUS","volume":"9 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/sscp.70196","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a disadvantage of the extraction process using the conventional decoction approach is the poor extraction rate. In this study, we employed network pharmacology to screen for active components for the treatment of COPD, and we optimized the extraction procedure of the fatty oil of Sanzi Yangqin Decoction with the Box–Behnken response surface test. Based on the single‐factor experiment and the Box–Behnken response surface test, the liquid chromatography‐triple quadrupole mass spectrometry method (LC‐MS/MS) to measure these four components has been constructed with the extraction time, extraction temperature, and liquid‐to‐feed ratio as examining factors and the composite scores of the extracted amounts of the four components as examining indexes. According to the results of the study, luteolin, arachidonic acid, sinoacutine, and sinapine thiocyanate have been selected as the analytes for determining the fat oil content of Sanzi Yangqin Decoction. The most effective extraction conditions were 4.1 h, 92°C, and a liquid‐to‐feed ratio of 10:1 mL/g, which achieved a composite score of 85.1. The methodological analysis of the LC‐MS/MS methodology demonstrated that the precision, repeatability, and sample recovery all proved effective, and the linear relationship was good within the range of the four constituents. The optimized Sanzi Yangqin Decoction fatty oil extraction process is reasonable and feasible. And the LC‐MS/MS content determination method is simple, rapid, sensitive, and specific. This work introduces an innovative approach to examining the fatty oils in Sanzi Yangqin Decoction.","PeriodicalId":21639,"journal":{"name":"SEPARATION SCIENCE PLUS","volume":"8 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/sscp.70105","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, the roots of P. cyrtonema are used medicinally, while the potential value of its above‐ground parts, such as the leaves, remains underexplored. Preliminary research revealed that the leaves of P. cyrtonema exhibit remarkable antioxidant activity, suggesting the presence of abundant flavonoid compounds. To efficiently isolate these active components, a systematic separation method based on medium‐pressure preparative chromatography (MPLC) combined with preparative high‐performance liquid chromatography (Prep‐HPLC) was developed. Initially, flavonoids were enriched using MPLC with an MCI GEL R CHP20P stationary phase and a water/ethanol linear gradient elution for selective enrichment of target compounds. Subsequently, the enriched compounds were further separated by Prep‐HPLC on a Megress C18 column, guided by ultraviolet (UV) spectroscopy. This integrated strategy successfully isolated nine flavonoid compounds from the leaves of P. cyrtonema , seven of which are novel and reported for the first time, with purities exceeding 96%. Compared to traditional separation methods, the developed approach exhibits superior advantages in terms of visualization, systematicity, reproducibility, and efficiency. It not only provides a targeted and efficient means for the isolation of flavonoid compounds from P. cyrtonema leaves but also serves as a valuable reference for the separation of bioactive compounds from other medicinal plants.","PeriodicalId":21639,"journal":{"name":"SEPARATION SCIENCE PLUS","volume":"8 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147330982","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}

In tea plant ( Camellia sinensis ) cultivation, the application of pesticides and herbicides constitutes a common agricultural practice for integrated pest management and weed control. Researchers usually focus on the pesticide residues in tea itself and rarely study the pesticide residues in tea soup. This study presents a rapid quantitative analysis method for detecting 36 common pesticides in green tea soup. The method involves using effervescent‐assisted extraction combined with dispersive liquid–liquid microextraction. Pesticides in tea soup are extracted with nonanoic acid, and during the extraction process, sodium carbonate solution (Na 2 CO 3 solution) and sulfuric acid (H 2 SO 4 ) are added to produce carbon dioxide for auxiliary extraction. The solidified substances are then dissolved in methanol and analyzed using LC–MS/MS. This study revealed that the 36 target pesticides exhibited strong linear responses across a concentration range of 1–50 ng mL −1 , with correlation coefficients ( R 2 ) exceeding 0.99. The developed method demonstrated a limit of quantification (LOQ) of 0.1 µg L −1 , accompanied by recovery rates ranging from 76.3% to 101.4% and relative standard deviations (RSDs) below 6.7% across all validation parameters. This approach is cost‐effective, minimizes the use of organic reagents, and reduces environmental pollution. Overall, the combination of effervescent‐assisted extraction and dispersive liquid–liquid microextraction is efficient for detecting pesticides in tea soup, making it suitable for routine analysis of commonly used pesticides in green tea soup.","PeriodicalId":21639,"journal":{"name":"SEPARATION SCIENCE PLUS","volume":"8 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333960","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}
