Two new compounds from the flowers of Rhododendron molle

Abstract Aim To study the chemical constituents of the flowers of Rhododendron molle . Methods Compounds were isolated 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 Compounds 1 and 2 were identified as two new compounds: 2 α , 10 α -epoxy-3 β , 5 β , 6 β , 14 β , 16 α -hexahydroxy-grayanane and benzyl 2, 6-dihydroxybenzoate-6- O-α -L-rhamnopyranosyl-(1→3)- β -D-glucopyranoside, respectively.
