摘要：

The highly-polar fractions of the nonsaponifiable lipids obtained from the methanol extracts of 10 Cucurbitaceae seed materials were investigated for their components. Fourteen dihydroxy triterpenes and their derivatives, and one oxo-sterol were characterized. They are 7-oxodihydrokarounidiol-3-benzoate (7-oxomultiflor-8-ene-3 alpha, 29-diol-3-benzoate), isokarounidiol-3-p-methoxybenzoate (multiflora-6, 8-diene-3 alpha, 29-diol-3-p-methoxybenzoate), karounidiol-3-benzoate, karounidiol, isokarounidiol, 5-dehydrokarounidiol, 7-oxodihydrokaroudnidiol, bryonolol, 3-epibryonolol, loranthol, betulin, 29-hydroxylupeol, erythrodiol, (23Z)-cycloart-23-ene-3 beta, 25-diol and 7-oxositosterol among which the first two were the new naturally occurring compounds. Karounidiol and 7-oxodihydrokarounidiol were detected in all of the investigated seed materials. (C) 1997 Elsevier Science Ltd.
