Studies on chemical constituents from roots of Cudrania cochinchinensis / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents from the roots of Cudrania cochinchinensis.</p><p><b>METHOD</b>The chemical constituents of C. cochinchinensis were isolated and purified by silica gel, polyamide column chromatography, Their structures were identified on the basis of spectroscopic data.</p><p><b>RESULT</b>Six compounds were isolated and identified. Their structures were established as 3, 5, 7, 4"-tetrahydroxyflavanone-7-O-(6"-acetyl)-glucoside (1), 3, 5, 7, 4'-tetra hydroxyflavanone-7-O-glucoside (2), 2', 4', 5, 7-tetrahydroxy-6-prenyldihydroflavanone (3), 5, 7, 4'-trihysdroxy-6-prenylisoflavanone (4), 1, 3, 5, 6-tetrahydroxyxanthone (5), stilbene-2, 4, 3', 5'-tetraol (6).</p><p><b>CONCLUSION</b>Compound 1 was isolated from this genus, while compounds 4 and 5 were isolated from this plant for the first time.</p>
