title: [Diterpenoids from Scutellaria strigillosa].
abstract: By means of preparative HPTLC and column chromatography over silica gel and Sephadex LH-20, nine diterpenoids were isolated and purified from the whole plants of Scutellaria strigillosa. Based on the physico-chemical properties and spectral data, their structures were elucidated as: 6-O-acetyl-7-O-nicotinoylscutebarbatine G(1), 6-O-nicotinoyl-7-O-acetylscutebarbatine G(2), 6,7-di-O-nicotinoylscutebarbatine G(3), scutebarbatine K(4), scutebarbatine B(5), 6-O-acetylscutehenanine A(6), 6-O-nicotinoylbarba- tin A(7), 6,7-di-O-acetoxylbarbatin A(8), scutebarbatine F(9). Compound 1 is a new diterpenoid, and compounds 2-9 were isolated from Scutellaria strigillosa for the first time.
