The structure of the title compound, a pentacyclic triterpenoid isolated from Clinopodium Polycephalum (Vant.) C. Y. Wu et Hsuan, has been determined by X-ray crystallographic analysis. C29H44O2,Mr=424.67, monocli-nic, P21,a=10.753(2), b=7.705(2), c=15.336(2)A,β=101.47(1)°, V=1245.2(7) A3,Z=2, Dx=1.133gcm-3,μ(Mo-Kα)=0.64cm-1, F(000)=468, 294K. Ths structure was solved by direct methods and refined to R=0.050 for 2269 observed MoKd reflections.
