Ft. Halaweish et Dw. Tallamy, A NEW CUCURBITACIN PROFILE FOR CUCURBITA-ANDREANA - A CANDIDATE FOR CUCURBITACIN TISSUE-CULTURE, Journal of chemical ecology, 19(6), 1993, pp. 1135-1141
In addition to previously reported cucurbitacins B, 1, and D, 2, cucur
bitacin E, 3, and 1, 4, aglycones and their glucosides 2-O-beta-glucop
yranosyl-cucurbitacin E, 5, and 2-O-beta-glucopyranosyl-cucurbitacin 1
, 6, were isolated and identified as constituents of Cucurbita andrean
a on the basis of MS, FD-MS, H-1 NMR and C-13 NMR spectroscopy. Also,
2-O-beta-glucopyranosyl-cucurbitacin B, 7, cucurbitacin B glucoside wa
