作者首次从欧益母草变种 Leonurus car-diaca var.vulgaris[Moenoh] Briquet 地上部分分得一苯丙烷苷类化合物薰衣草水苏苷(lavandulifolioside),并研究了其药理作用。该植物地上部分风干后用氯仿和甲醇提取。甲醇提取物溶于水中,用乙醚、乙酸乙酯和正丁醇分配提取。正丁醇部位进一步层析得薰衣草水苏苷。药理实验显示,丁醇提取物在1～20μg 时对大鼠离体心脏的心率无明显影响,50～2000μg 时降低心率25%～ For the first time, the author obtained a phenylpropanoid lavandulifolioside from Leonurus car-diaca var. vulgaris [Moenoh] Briquet, and studied its pharmacological effects. The aerial part of the plant was air-dried and extracted with chloroform and methanol. The methanol extract was dissolved in water and partitioned with ether, ethyl acetate and n-butanol. The n-butanol moiety was further chromatographed to obtain lavender stadioside. Pharmacological experiments showed that the butanol extract had no significant effect on the heart rate of isolated rat hearts at 1-20 μg, and decreased the heart rate by 25% from 50 to 2000 μg.
