摘　　要：Two new phenolic glycosides, everninic acid methyl ester-2-O-b-D- xylopyran- osyl-(16)-b-D-glucopyranoside 1 and 7-hydroxy-5-methoxyphthalide-7-b-D- xylopyranosyl- (16)-b-D-glucopyranoside 2 were isolated from the roots of Rhododendron molle G. Don. Their structures were determined by spectral evidence including 2D NMR techniques.Two new phenolic glycosides, everninic acid methyl ester-2-O-b-D- xylopyran- osyl-(16)-b-D-glucopyranoside 1 and 7-hydroxy-5-methoxyphthalide-7-b-D- xylopyranosyl- (16)-b-D-glucopyranoside 2 were isolated from the roots of Rhododendron molle G.
