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