Quick method for separating target compounds from the bark of Maqian (Zanthoxylum myriacanthum var. pubescens) by high-performance countercurrent chromatography.[Pubmed: 27557568]
Choosing a suitable solvent system for a countercurrent chromatography separation presents a challenge for many researchers. In this study, we introduce a quick method of separating a target compound from the bark of Zanthoxylum myriacanthum var. pubescens by countercurrent chromatography. This method relies on the thin-layer chromatography based generally useful estimation of solvent systems. This paper will present how to quickly choose a suitable solvent system with a thin-layer chromatography based generally useful estimation of solvent systems working chart. O-Methyltembamide (1) was enriched by countercurrent chromatography using n-hexane/ethyl acetate/methanol/water (6:4:6:4) as the solvent system. Further purification was achieved by high-performance liquid chromatography with purities of 98.2% from Z. myriacanthum var. pubescens bark.
Protective effect of the essential oil of Zanthoxylum myriacanthum var. pubescens against dextran sulfate sodium-induced intestinal inflammation in mice.[Pubmed: 27387396]
Zanthoxylum myriacanthum var. pubescens is an ethnic medicine for digestive disease known as Maqian. A previous report showed that the Maqian fruits essential oil (MQEO) exhibited an NO inhibitory effect on RAW 264.7 cells, but the effect on inflammatory disease in vivo remains unknown.
Chemical composition, antimicrobial and anti-inflammatory activities of the essential oil from Maqian (Zanthoxylum myriacanthum var. pubescens) in Xishuangbanna, SW China.[Pubmed: 25448503]
Maqian (Zanthoxylum myriacanthum var. pubescens Huang) is widely consumed as an indigenous remedy for digestive disorders, detoxification, detumescence and analgesia by the ethnic groups in Xishuangbanna, SW China. A related species, Huajiao (Zanthoxylum schinifolium Sieb. et Zucc.), has similar uses in traditional Chinese medicine. We aimed to scientifically validate the traditional uses by investigating and comparing the chemical composition, antimicrobial and anti-inflammatory activities of the essential oils of Maqian and Huajiao.
