Abstract
A new p-coumaroylate of maslinic acid was isolated from the fruits of Zizyphus jujuba (Rhamnaceae) together with known triterpenoid acids : betulonic, oleanonic, maslinic and 3-O-trans-p-coumaroyl maslinic acid. The structure of V was characterized to be 3-O-cis-p-coumaroyl maslinic acid on the basis of chemical and spectral evidence.
