Chemical constituents from herbs of Erigeron breviscapus / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents from herbs of Erigeron breviscapus.</p><p><b>METHOD</b>The compounds were isolated and purified by various chromatographic techniques. Their structures were identified on the basis of physicochemical properties and spectral analysis.</p><p><b>RESULT</b>Twelve compounds were isolated and structurally identified as quercetin-3-O-beta-D-glucoside (1), 5, 7-dihydroxychromone (2), 3-O-caffeoyl-gamma-quinide (3), naringenin (4), 3, 5-di-O-caffeoylquinic acid (5), 3,4-di-O-caffeoylquinic acid (6), 4, 5-di-O-caffeoylquinic acid (7), 1,3-di-O-caffeoylquinic acid (8), 1, 5-di-O-caffeoylquinic acid (9), 3-O-caffeoylquinic acid (10), 4-O-caffeoylquinic acid (11) and chlorogenic acid (12).</p><p><b>CONCLUSION</b>Compounds 1-4 were isolated from this plant for the first time.</p>
