The chemical constituents of Rhododendron ovatum Planch / 药学学报

ABSTRACT

Aim To study the chemical constituents of Rhododendron ovatum Planch. Methods The chemical constituents were isolated and purified by silica gel column chromatography and identified on the basis of their physiochemical and spectral data. Results Seven compounds were isolated and identified. Their structures were established as 3,5,7-trihydroxylchromone 3-O-β-D-xylopyranoside (I), taraxerol (II), β-sitosterol (III), betulinic acid (IV), quercetin (V), quercetin-3-O-α-L-rhamnopyranoside (VI), and D-glucose (VII). Conclusion Compound I is a new compound. Compounds II-VII were isolated from this plant for the first time.
