Studies on the flavonoid compounds of Rhododendron anthopogonoides / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the flavonoid constituents of the Rhododendron anthopogonoides systematically.</p><p><b>METHOD</b>The chemical components were isolated by sephadex LH-20, polyamide and silica gel column chromatography. The chemical structures were elucidated on the basis of physic-chemical properties and spectral data.</p><p><b>RESULT</b>Eight compounds were isolated and identified as Quercetin (I), isorhamnetin (II), hyperoside (III), cacticin (IV), hirsutine (V), kaemferol-3-beta-D-galactoside (VI) myricetin-3-beta-D-Xyloside (VII), (6''-O-(4-Hydroxybenzoyl) hyperoside (VIII).</p><p><b>CONCLUSION</b>Compounds II, IV, V, VI, VII, and VIII were obtained from this plant for the first time. Compounds VII and VIII were separated from the Ericaceae plant for the first time.</p>
