| Abstract: | AIM： To study the chemical constituents of the flowers of Rhododendron moUe. METHODS： Compounds were iso- lated by repeated chromatography over silica gel and Sephadex LH-20. Structures were elucidated based on spectral techniques, mainly 1D- and 2D-NMR and mass spectrometric analyses. RESULTS： Two compounds （1 and 2） were isolated. CONCLUSIONS： Com- pounds 1 and 2 were identified as two new compounds： 2α, 10α-epoxy-3β,5β,6β,14β,16α-hexahydroxy-grayanane and benzyl 2, 6-dihydroxybenzoate-6-O-α-L-rhamnopyranosyl-（1→3）-β-D-glucopyranoside, respectively. |
