Studies on chemical constituents of cytotoxic fraction from leaves of Elaeagnus pungens / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents possessing cytotoxicity activity from Elaeagnus pungens.</p><p><b>METHOD</b>The constituents were separated through repeated chromatographic methods and their structures were elucidated by spectral analysis.</p><p><b>RESULT</b>Five compounds were isolated from the ethyl acetate ether extract of leaves of E. pungens. Their structures were elucidated as 4-hydroxybenzoic acid (1), 3, 3'-dimethoxyquercetin (2), caffeic acid methyl ester (3), methyl 3, 4-dihydroxybenzoate (4), spingic acid (5), 4-methoxylbenzoic acid (6), 3-methylkaempferol (7), kaempferol-3-O-beta-D-glucoside (8), dausosterol (9).</p><p><b>CONCLUSION</b>Compounds 1-8 were isolated from this plant for the first time.</p>
