从胡黄连（Picrorhiza kurrooa）根中分离得到3个葫芦素苷类化合物，并通过UV，~ 1H，~（13）C NMR，~ 2D ~ 1H，~ 1H-~（13）C NMR和质谱等方法鉴定了其结构。两种化合物，2 β-葡糖基氧基-3，16，20，25-四羟基-9-甲基-19-去甲羊毛甾-5，23-二烯-11，22-二酮和2 β-葡糖基氧基-16-20，22-三羟基-9-甲基-19-去甲羊毛甾-5，24-二烯-3，11-二酮是新的，其中一种，arvenin III，以前没有报道过作为该植物的成分。
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, 2.beta.-glucosyloxy-3,16,20,25-tetrahydroxy-9-methyl-19-norlanosta-5,23-diene-11,22-dione and 2.beta.-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.
