Triterpenes and triterpene glycosides from aerial part of Paraboea glutinosa / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the chemical constituents from aerial part of Paraboea glutinosa.</p><p><b>METHOD</b>The compounds were isolated with silica gel, Sephadex LH-20 column chromatography and their structures were elucidated by means of spectral data analysis.</p><p><b>RESULT</b>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).</p><p><b>CONCLUSION</b>All these compounds were isolated from the genus Paraboea for the first time.</p>
