摘要：

The crystal and molecular structure of the novel triterpenoid methyl 2 alpha,3 beta,23-triacetoxyurs- 12,18-dien-28-oate, C37H54O8, has been determined. There are two molecules in the asymmetric unit, each having a long bond due to steric effects and considerable out-of-plane bending at the C12=C13-C18=L19 chromophores.
