Abstract:
OBJECTIVETo investigate the flavonoid constituents of the Rhododendron anthopogonoides systematically.
METHODThe 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.
RESULTEight 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).
CONCLUSIONCompounds 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.
