Chemical constituents of Indigofera pseudotinctoria / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents in the roots of Indigofera pseudotinctoria.</p><p><b>METHOD</b>The constituents were isolated by column chromatography and their structures were elucidated by spectroscopic methods.</p><p><b>RESULT</b>Fourteen compounds were isolated from the ethanol extract of the plant and identified as maackiain (1), 3beta-hydroxy-olean-9 (11), 12-diene (2), 12-oleanen-3,11-dione (3), 3beta-acetoxy-12-oleanen-11 -one (4), formononetin (5), formononetin-7-O-beta-D- glucoside (6), 7,4'-dihydroxy-3'-methoxy isoflavone (7), afromosin (8), genistein (9), calycosin-7-O-beta-D-glucoside (10), vicenin-2 (11), isoliquiritigenin (12), beta-sitosterol (13), and daucosterol (14).</p><p><b>CONCLUSION</b>All compounds were isolated from the plant for the first time, eleven compounds (except 1, 13 and 14) were isolated from the genus Indigofera for the first time.</p>
