ABSTRACT squashThe flowers of Cucurbita maxima Duch. afforded a 4:1 mixture of spinasterol (1a) and 24-ethyl-5α-cholesta-7, 22, 25-trien-3β-ol (1b). Their structures were elucidated by extensive 1D and 2D NMR analyses. Antimicrobial activity tests on sample 1 indicated that it was slightly active against the fungi (Aspergillus niger and Candida albicans) and the bacteria (Bacillus subtilis and Pseudonomas aeruginosa). It was inactive against Escherichia coli, Staphylococus aureus, and Trichophyton mentagrophytes 56
