To investigate the chemical constituents from aerial part of Paraboea glutinosa.
The compounds were isolated with silica gel, Sephadex LH-20 column chromatography and their structures were elucidated by means of spectral data analysis.
Five compounds were isolated and identified as 2alpha, 3beta, 19alpha, 24-tetrahydroxyurs-12-en-28-oate(24-hydroxytormentic acid,1), glucosyl-2alpha, 3beta, 19alpha, 24-tetrahydroxyurs-12-en-28-oate (24-hydroxytormentic acid ester glucoside,2), 28-O-beta-D-glucopyranosyl (1-->6)-beta-D-glucopyranosyl-24-hydroxytormentic acid (3), beta-sitosterol (4), daucosterol (5).
All these compounds were isolated from the genus Paraboea for the first time.
研究黏毛蛛毛苣苔地上部分的化学成分。
采用硅胶柱色谱、葡聚糖凝胶LH-20柱色谱分离化合物，并通过光谱数据分析确定其结构。
分离鉴定了5个化合物，分别为2α,3β,19α,24-四羟基乌苏-12-烯-28-酸酯（24-羟基 tormentic 酸，1）、葡萄糖基-2α,3β,19α,24-四羟基乌苏-12-烯-28-酸酯（24-羟基 tormentic 酸酯葡萄糖苷，2）、28-O-β-D-吡喃葡萄糖基（1→6）-β-D-吡喃葡萄糖基-24-羟基 tormentic 酸（3）、β-谷甾醇（4）、胡萝卜苷（5）。
所有这些化合物均为首次从蛛毛苣苔属植物中分离得到。
