Four new cycloartane triterpenoids, 1α,3β-dihydroxy-16-keto-24(31)-en-cycloartane (1), 31-methoxyl-passifloic acid (2), cyclopassifloside XIV (3), and cyclopassifloside XV (4), together with six known compounds (5-10) were isolated from Passiflora edulis Sims. Their structures were elucidated on the basis of extensive spectroscopic analysis. All the compounds were evaluated for protective effects against damage of PC12 cell induced by glutamate according to traditional usage of the herbal medicine, and the results indicated that cycloartane triterpenoids maybe one of the active compositions of P. edulis Sims for the treatment of neurodegenerative disease.
