Article abstract of DOI:10.1016/0031-9422(82)83018-5

Eleven compounds isolated from the growth inhibiting active fraction of male flowers of Cucurbita pepo, were identified as p-hydroxybenzaldehyde, anisyl alcohol, p-hydroxybenzyl methyl ether, p-hydroxybenzyl alcohol, veratryl alcohol, isovanillyl alcohol, p-coumaric acid, phloretic acid, benzyl-β-D-glucoside, 4-methoxybenzyl-β-D-glucoside ans 3,4-dimethoxybenzyl-β-D-glucoside.Each compound was assayed for growth inhibiting activity using lettuce seedlings; three showed strong activity, whereas the glucosides were inactive.Key Word Index - Cucurbita pepo; Cucurbitaceae; male flowers; plant growth inhibitor; benzyl glucoside; 4-methoxybenzyl glucoside; 3,4-methoxybenzyl glucoside.
