Three new nor-cucurbitacin glucosides were isolated from the root of Caputo nigri (Cabeça-de-negro) and their structures established as 29-nor-1,2,3,4,5,10-dehydro-2,3,16 alpha,20R, 22 zeta,25-hexahydroxy-11-oxocucurbita-6,23-diene 2-O-beta-D-glucopyranoside and 2-O-beta-D-glucopyranosyl(1-2)beta-D- glucopyranoside(sophorose), and 1,2,3,4,5,10-dehydro-2,3,16 alpha-trihydroxy-4, 9,14-trimethyl-19-norpregn-6-ene-11,20-dione 2-O-beta-D-glucopyranoside on the basis of detailed spectroscopic analysis.
从黑卡普托（Cabeça-de-negro）的根部分离出三种新的去甲葫芦素糖苷，并通过详细的光谱分析确定它们的结构为29-去甲-1,2,3,4,5,10-脱氢-2,3,16α,20R,22ζ,25-六羟基-11-氧代葫芦巴-6,23-二烯2-O-β-D-吡喃葡萄糖苷和2-O-β-D-吡喃葡萄糖基（1→2）-β-D-吡喃葡萄糖苷（槐糖），以及1,2,3,4,5,10-脱氢-2,3,16α-三羟基-4,9,14-三甲基-19-去甲孕-6-烯-11,20-二酮2-O-β-D-吡喃葡萄糖苷。
