摘要
The title compound, C40H58O4, a lupane triterpene, was isolated from the hypocotyls of Ceriops tagal (Perr.) C. B. Robinson. There are two crystallographically independent molecules in the asymmetric unit. In both molecules, the cyclopentane ring adopts an envelope conformation. The molecular structure is stabilized by O-(HO)-O-... and C-(HO)-O-... hydrogen bonds. C-(HO)-O-... intermolecular hydrogen bonds link the molecules into chains along the a axis.
