diabetes [1]. In the present communication we give the results of a study of the flavonoids of the epigeal part of Glycyrrhiza uralensis Fisch. gathered in May, 1987 in the Tashkentskii oblast (village of Kibrai). The raw material was exhaustively extracted with ethanol. The alcoholic extract was concentrated in vacuum, diluted with water, and extracted successively with chloroform and ethyl acetate.

Glycyrrhiza L. (fam. Fabaceae) 属植物富含类黄酮、香豆素、萜类和鞣制物质,其中一些在民间医学中用于治疗肺炎、支气管炎、支气管哮喘、肺结核、百日咳咳嗽、消化性溃疡、肾脏和胆囊疾病、贫血和糖糖尿病 [1]。在本通讯中,我们给出了甘草表皮部分黄酮类化合物的研究结果。1987 年 5 月在塔什干州 (Kibrai 村) 聚集。原料用乙醇彻底提取。真空浓缩醇提物,用水稀释,依次用氯仿和乙酸乙酯萃取。在氯仿石油醚梯度系统和氯仿中在硅胶上对乙酸乙酯级分进行色谱分离,分离出化合物 (1)-(3)。为了识别它们,我们使用了 UV、PMR 和质谱以及化学转化的结果和与真实样本的直接比较。Glabranin (1) [5,7-二羟基-8-(3,,-g-二甲基烯丙基)黄烷酮] C20H2004,mp 168-169~(甲醇),Xmax 297,344 nm,黄烷酮衍生物的特征 [2]。质谱显示
