New cycloartane triterpenoids from Passiflora edulis.
Three cycloartane triterpenes, cyclopassifloic acids E (1), F (2), and G (3), and their saponins, cyclopassiflosides VII (4), VIII (5), IX (6), X (7), and XI (8), were isolated from the leaf and stem parts of Passiflora edulis. The structures of 1-8 were elucidated on the basis of extensive NMR experiments and by chemical methods.
