Water-soluble chemical constituents from Elaeagnus pungens leaves / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study water-soluble chemical constituents from the leaves of Elaeagnus pungens.</p><p><b>METHOD</b>Chemical constituents of E. pungens leaves were separated by a combination of macroporous resin column chromatography, reverse phase silica gel column chromatography, Sephadex LH-20 column chromatography and semi-preparative HPLC. Their structures were identified on the basis of physicochemical properties using the spectral method.</p><p><b>RESULT</b>The two compounds were separated from E. pungens leaves and identified as kaempferol 3-O-P-D-glucopyranosyl- (1-->3)-alpha-L-rhamn-opyranosyl-(1-->6) -/3-D-galactopyranoside (1), kaempferol 3-O-P-D-glucopyranosyl-(1-->3)-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside-7-O-beta-D-glucopyranoside (2).</p><p><b>CONCLUSION</b>Compound 2 separated from E. pungens leaves was a new compound.</p>
