研究表明巴西蜂胶具有抗菌、抗肿瘤、抗氧化、免疫调节、抗真菌等作用。本次从巴西蜂胶的精油中分离并鉴定出2种新成分(1、2)和7种已知化合物。 巴西蜂胶(550g)按《日本药典》记载方法水蒸汽蒸馏5h,蒸馏物用乙醚提取,乙醚提取液经无水硫酸钠干燥,蒸发除去溶剂,得到的精油经硅胶柱分离,制备型TLC纯化,得到新成分1、2和7种已知成分2,2- Research shows that Brazilian propolis has antibacterial, anti-tumor, anti-oxidation, immune regulation, anti-fungal and other effects. Two new components (1, 2) and 7 known compounds were isolated and identified from the essential oil of Brazilian propolis. The Brazilian propolis (550 g) was steam distilled for 5 h according to the method described in the “Japanese Pharmacopoeia”. The distillate was extracted with ether. The ether extract was dried over anhydrous sodium sulfate and evaporated to remove the solvent. The essential oil was separated on a silica gel column and purified by preparative TLC.
