摘 要 ：从小红参(Rubia yunnanensis Diels.)中分得3个乔木烷型三甙成分，其中2个为新化合物，经光谱解析与化学方法证明其结构为3β,7β，28-三羟基-19α-乙酰氧基乔木-9(11)-烯和7β，28-二羟基-19α-乙酰氧基乔木-9(11)-烯-3-酮,并分别命名为茜草乔木醇G和茜草乔木酮A。另一个化合物为已知茜草乔木醇A。

Abstract:Two new arborane type triterpenoids, rubiarbonol G (1) and rubiarbonone A (2), to-gether with rubiarbonol A, were isolated from the roots of Rubia yunnanensis Diels. Their structures were elucidated as 19a-acetoxy-3/?, 1p, 28-trihydroxy-arbor-9 (11) -ene and 19a-acetoxy-7^, 28-dihydroxyarbor-9 (11) -en-3-one by spectral and chemical methods, respectively.
