Abstract:
AIMTo study the chemical constituents of Rhododendron ovatum Planch.
METHODSThe chemical constituents were isolated and purified by silica gel column chromatography and identified on the basis of their physiochemical and spectral data.
RESULTSSeven 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).
CONCLUSIONCompound I is a new compound. Compounds II-VII were isolated from this plant for the first time.
