    Author: Dai SJ, Chen RY, Yu DQ.
    Journal: Zhongguo Zhong Yao Za Zhi; 2004 Jan; 29(1):44-7. PubMed ID: 15709380.
    Abstract:
    OBJECTIVE: To investigate the flavonoid constituents of the Rhododendron anthopogonoides systematically. METHOD: 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. RESULT: 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). CONCLUSION: 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.
