Steroidal and triterpenoidal glucosides from Passiflora alata

Five glycosides were isolated from leaves of P. alata. The structures 1-5 w ere obtained through extensive spectral analyses as 3-O-beta -D-glucopyrano syl-stigmasterol (1), 3-O-beta -D-glucopyranosyloleanolic acid (2), 3-O-bet a -D-glucopyranosyl-(1-->3)-beta -D-glucopyranosyl- oleanolic acid (3), 3-O -beta- D-glucopyranosyl-(1-->2)-beta -D-glucopyranosyl-oleanolic acid (4) a nd 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 leav es 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.
