从滇藏筋骨草(Ajuga forrestii)全草中分离得到4个桉烷型倍半萜内酯(1-4)和7个松香烷型二萜(5-11)。其中,3 α-乙酰氧基-1 α,8 β-二羟基桉烷-7(11)-烯-8,12-酮(1)、3 α-乙酰氧基-1 α-羟基桉烷-8,7(11)-二烯-8,12-酮(2)、1 α-乙酰氧基-8 α-氧乙基-2-氧代桉烷-3,7(11)-二烯-8,12-酮(3)和2 α,3 β,11,12-四羟基-7 β,20-环氧-8,11,13-松香三烯(11)是新化合物。化合物1-11的结构通过光谱分析确定。化合物2对HepG 2和MCF-7细胞株表现出弱的细胞毒性。版权所有(C)2013欧洲植物化学学会。Elsevier B.

Four eudesmane sesquiterpenoid lactones (1-4) and seven abietane diterpenoids (5-11) were isolated from the whole plants of Ajuga forrestii. Among them, 3 alpha-acetoxy-1 alpha,8 beta-dihydroxyeudesm-7(11)-en-8,12-olide (1), 3 alpha-acetoxy-1 alpha-hydroxyl-eudesm-8,7(11)-dien-8,12-olide (2), 1 alpha-acetoxy-8 alpha-oxyethyl-2-oxo-eudesman-3,7(11)-dien-8,12-olide (3) and 2 alpha,3 beta,11,12-tetrahydroxy-7 beta,20-epoxy-8,11,13-abietatriene (11) are novel compounds. The structures of compounds 1-11 were determined by spectroscopic analysis. Compound 2 exhibited weak cytotoxicity on HepG2 and MCF-7 cell lines.
