摘要
从毛萼鞘蕊花(Coleus esquirolii(Levl.)Dunn)全草中分到3个新的二萜,毛萼鞘蕊花乙素(esquirolin B)(1),毛萼鞘蕊花丙素(esquirolin C)(2),毛萼鞘蕊花丁素(esquirolin)(3),和2个已知化合物,cariocal(4)和蒲公英赛醇(taraxerol)。
Three new diterpenoids named esquirolin B(1), C(2), D(3) respectively and two known compounds carioca] (4) and taraxerol were isolated from Caleus esquirolii (Levl.) Dunn, by column chromatography on silica gel. The structures of esquirolin B(1), C(2), D(3) were elucidated as 13-epi-7(8)-isopimaren-15,16-diol(1), 15,16-acteonide-13-epi-7(8)-isopimarene (2) and (20S)-6β, 11,12-trihydroxy-20-methoxy-7β, 20-epoxy-abieta-8,11, 13-triene (3) by chemical and spectroscopic methods.
