摘要：

From the roots of Picrorhiza kurrooa three cucurbitacin glycosides were isolated and structurally elucidated mainly by means of UV, 1H, 13C NMR, 2D 1H, 1H-13C NMR and mass spectroscopy. Two of the compounds, 2β-glucosyloxy-3,16,20,25-tetrahydroxy-9-methyl-19-norlanosta-5,23-diene-11,22-dione and 2β-glucosyloxy-16,20, 22-trihydroxy-9-methyl-19-norlanosta-5,24-diene-3,11-dione, are new and one, arvenin III, has not been reported previously as a constituent of this plant. © 1990.
