title: A new cucurbitacin profile forCucurbita andreana: A candidate for cucurbitacin tissue culture.
abstract: In addition to previously reported cucurbitacins B,1, and D,2, cucurbitacin E,3, and I,4, aglycones and their glucosides 2-O-β-glucopyranosyl-cucurbitacin E,5, and 2-O-β-glucopyranosyl-cucurbitacin I,6, were isolated and identified as constituents ofCucurbita andreana on the basis of MS, FD-MS, 1 H NMR and(13)C NMR spectroscopy. Also, 2-O-β-glucopy-ranosyl-cucurbitacin B, 7, cucurbitacin B glucoside was isolated and identified.
