Abstract:
药囊花(Cyphotheca montana Diels)茎叶的乙醇提取物具有抗菌活性,进一步的活性追踪表明活性成分在乙酸乙酯和正丁醇萃取物中。我们从这两种萃取物中共分离鉴定出9个化合物,其结构通过波谱分析等分别鉴定为:槲皮素-3-O-α-L-鼠李糖甙(1)、杨梅素-3-O-α-L-鼠李糖甙(2)、山萘酚-3-(2″,6″-二-O-(E)-p-羟基苯丙烯酰-β-D-吡喃葡萄糖甙(3)、3,3′-O-二甲基逆没食子酸-4-O-β-D-吡喃葡萄糖甙(4)、槲皮素(5)、2α,3β,19α,23-四羟基乌苏-12,烯-28-酸-28-O-β-吡喃葡萄糖甙(6)、乌苏酸(7)、β-谷甾醇(8)和胡萝卜甙(9)。这些化合物均为首次从我国该特有单种属植物中分离得到。
