摘要
二萜佛司可林E、F、G、H,已从毛喉鞘蕊花分离得到。本文根据一维和二维的核磁共振谱详细描述了它们的光谱特征,改正了原先错误的指定。
Diterpenoids, forskolin E(7,1α,7β-diaeetoxy-6β-hydroxy-8,13-epoxy-labd-14-en- 11-one ), forskolin F( 8,7β-aeetoxy- 6β,9α-dihydroxy-8, 13-epoxy-lalxi-14-en-11-one), forskolin G (9, 1α-hydroxy-6β, 7β-diaeetoxy-8, 13-epoxy-labd-14-en-ll- one), forskolin H(10, 1α,6β-diaeetoxy-8,13-epoxy-labd-14-en-11-one) ,were isolated from isolated from Coleus forskohlii(Willd. )Briq.This paper describes detailedly their spectral charaeteries,ineluding 1D and 2D NMR data.
