摘要：

Seven new cucurbitacins were isolated from the roots of Picrorhiza kurrooa. On the basis of UV, H-1, C-13 NMR, 2D H-1, H-1-C-13 NMR and mass spectroscopy their structures were determined as 25-(acetyloxy)-2-(beta-D-glucopyranosyloxy)-3,16-dihydroxy-9-methyl-19-norlanosta-5,23-dien-22-one, 25-(acetyloy)-2-(beta-D-glucopyranosyloxy)-3,16,20-trihydroxy-9-methyl-19-norlanosta-5,23(Z)-dien-22-one, 25-(acetyloxy)-2- (beta-D-glucopyranosyloxy)-3,16,20-trihydroxy-9-methyl-19-norlanost-5-en- 22-one, 2-(beta-D-glucopyranosyloxy)-3,16,20-trihydroxy-9-methyl-19- norlanosta-5,24-dien-22-one, 2-(beta-D-glucopyranosyloxy)-3,16- dihydroxy-4,4,9,14-tetramethyl-19-norpregn-5-en-20-one, 2,3,16,20,25-pentahydroxy-9-methyl-19-norlanost-5-en-22-one, 2-(6-O-cinnamoyl-beta-D- glucopyranosyloxy)-3,16,20,25-tetrahydroxy-9-methyl-19-norlanost-5-en-22-on.
