Abstract:
Two new cucurbitacins I (1 and 2), together with eight known compounds (3-10), were isolated from the ethyl acetate extract of the fruit of Citrullus colocynthis. Compounds 3, 5-9 were isolated from C. colocynthis for the first time. The structures of new compounds were determined primarily from IR, HR-MS, 1D-, and 2D-NMR analysis.
