Abstract
A new ursane-type triterpene, named as cheiranthic acid (1), was isolated from the MeOH extract of whole plants of Oenothera cheiranthifolia (Onagraceae) along with an isomeric pair of known oleanane- and ursane-type triterpenes (arjunolic acid and asiatic acid) and three flavonol glucuronide analogues (quercetin 3-O-glucuronide, its n-butyl ester, and myricetin 3-O-glucuronide). Their structures were elucidated based on spectroscopic evidence.Entities:
