摘要：
Five glycosides were isolated from leaves of P. alata. The structures 1-5 were obtained through extensive spectral analyses as 3-O-beta -D-glucopyranosyl-stigmasterol (1), 3-O-beta -D-glucopyranosyloleanolic acid (2), 3-O-beta -D-glucopyranosyl-(1-->3)-beta -D-glucopyranosyl- oleanolic acid (3), 3-O-beta- D-glucopyranosyl-(1-->2)-beta -D-glucopyranosyl-oleanolic acid (4) and 9,19-cyclolanost-24Z-en-3 beta, 21,26-trihydroxy-3,26-di-O-gentiobiose (5). Comparison of the TLC profiles of the hydroethanolic extracts from leaves of other Passiflora species found in the south of Brazil (P. actinia, P. caerulea, P. edulis var. flavicarpa, P. elegans, P. foetida, P. misera and P. tenuifila) showed that only P. alata presented saponin accumulation.
