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-beta-D-xylopyranoside (I), taraxerol (II), beta-sitosterol (III), betulinic acid (IV), quercetin (V), quercetin-3-O-alpha-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.
