浮萍甾醇类和脂类化学成分研究

Steroids and Lipids from Spirodela polyrrhiza

从中药浮萍的乙醇提取物中分离出4种成分,经理化常数和波谱数据鉴定,其结构分别为豆甾醇(stigmasterol)、单棕榈酸甘油酯(monopalmitic glycerate)、胡萝卜甙(daucosterol)和棕榈酸(palmiticacid),其中单棕榈酸甘油酯为首次从该种植物中分离得到。

Two steroids and two lipids were isolated from the ethanolic extract of Spirodela polyrrhiza. Their structures were identified by spectral analysis and chemical evidence, which were identified as sbgmasterol, monopalmitic glycerate, daucosterol and palmitic acid. Monopalmitic glycerate was discovered from this plant for the first time.
