Chemical constituents contained in aerial parts of Emilia sonchifolia / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents contained in ethanol extracts from aerial parts of Emilia sonchifolia.</p><p><b>METHOD</b>The compounds were separated and purified with various chromatographic techniques, and their structures were identified on the basis of physicochemical properties and spectral data.</p><p><b>RESULT</b>Fifteen compounds were separated from ethyl acetate fraction of 90% ethanolic extract and identified as rhamnetin (1), isorhamnetin (2), quercetin (3), luteolin (4), tricin-7-O-beta-D-glucopyranoside (5), 8-(2"-pyrrolidinone-5"-yl) -quercetin (6), 5, -2', 6'-trihydroxy-7, 8-dimethoxyflavone-2'-O-beta-D-glucopyranoside (7), succinic acid (8), fumaric acid (9), p-hydroxybenzoic acid (10), 4-hydroxy isophthalic acid (11), 3, 4-dihydroxycinnamic acid (12), esculetin (13), isowedelolactone (14) and uracil (15), respectively.</p><p><b>CONCLUSION</b>All compounds except compound 3 were separated from this genus for the first time.</p>
