Triterpene glycosides related to quadranguloside from Passiflora quadrangularis / F. Orsini, F. Pelizzoni, G. Ricca, L. Verotta. - In: PHYTOCHEMISTRY. - ISSN 0031-9422. - 26:4(1987), pp. 1101-1105. [10.1016/S0031-9422(00)82358-4]
Abstract:
Two new cyclopropane triterpene glycosides were isolated from the methanol extracts of leaves of Passiflora quadrangularis. On the basis of hydrolysis, spectral evidence and comparison with quadranguloside, these compounds were assigned the structures 9,19-cyclolanosta-22,25-epoxy-3β-21,22(R)-triol-3β-O-gentiobioside and 9,19-cyclolanosta-21,24-epoxy-3β-25,26-triol-3β-O-gentiobioside,respectively. Oleanolic acid-3-sophoroside was also isolated for the first time from a natural source.
