摘要:
从江苏土元胡Corydalis humosa Migo的块茎中分得15个化合物,鉴定了其中12个化合物,包括3个曾从该植物中得到的生物碱:普鲁托品(protopine,Ⅰ),(一)-四氢黄连碱(l-tetrahydrocoptisine,Ⅳ)和毕枯枯灵(bicuculline,Ⅶ);8个生物碱为首次从该植物中得到:氢化普鲁托品(hydroprotopine,Ⅱ),dl-四氢黄连碱(dl-tetrahydrocoptisine,Ⅳ_2),dl-四氢小檗碱(dl-tetrahydroberberine,Ⅴ),降氧化北美黄连次碱(noroxyhydrastinine,Ⅵ),隐品碱(cryptopine,Ⅸ),黄连碱(coptisine,Ⅲ),巴马汀(palmatine,Ⅻ)及去氢碎叶紫堇碱(dehydrocheilanthifoline,x);1个为新的天然内酯化合物,命名为元胡内酯(coryhumolide,Ⅷ)。
