To study the chemical constituents of the flowers of Rhododendron molle.
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.
Two compounds (1 and 2) were isolated.
Compounds 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.
研究密枝杜鹃的花化学成分。
用硅胶和 Sephadex LH-20 反复层析分离化合物。根据光谱技术，主要是 1D-和 2D-NMR 和质谱分析来阐明结构。
分离得到两种化合物（1 和 2）。
化合物 1 和 2 被鉴定为两种新化合物：2α，10α-环氧-3β，5β，6β，14β，16α-六羟基灰杨烷和苯甲基 2,6-二羟基苯甲酸-6-O-α-L-鼠李吡喃糖苷-(1→3)-β-D-吡喃葡萄糖苷。
