Abstract From the crude drug ‘Ipecac’ (dried root of Cephaelis ipecacuanha) six novel tetrahydroisoquinoline-monoterpene glucosides, 6-O-methylipecoside, ipecosidic acid, demethylalangiside, neoipecoside, 7-O-methyl-neoipecoside and 3,4-dehydroneoipecoside were isolated along with ipecoside, alangiside, sweroside and 7-dehydrologanin. The structures of new glucosides were determined by spectroscopic
摘要 从生药“吐根”中分离得到六种新型四氢异喹啉-单萜苷、6-O-甲基-异戊二烯苷、异异氰酸酯、去甲基黄芩苷、新异松苷、7-O-甲基-异异戊二烯苷和3,4-异异戊二烯糖苷。连同伊佩考苷、阿兰糖苷、鼠尾草苷和 7-脱氢木糖苷。通过光谱和化学方法确定了新糖苷的结构。还讨论了这些糖苷的生物发生。
