摘要
目的:研究樱草杜鹃(Rhododendron primulaeflorum)的干燥地上部分的化学成分。方法:应用硅胶柱色谱,Sephadex LH-20柱色谱,制备高效液相色谱等方法分离和纯化化合物, 通过光谱方法及理化性质鉴定化合物的结构。结果:从樱草杜鹃中分离得到1个新化合物,鉴定为2-羟基-6-甲基苯甲酸甲酯4-O-β-D-葡萄糖苷(1),及苔色酸甲酯(2)。结论:从该植物中分得一个新化合物,丰富了樱草杜鹃的化学成分。
AIM： To study the chemical constituents of the aerial parts of Rhododendron primulaeflorum Bur. et Franch. METHODS： The solvent extraction, Sephadex LH-20, silica gel column chromatography and pre-HPLC were used to isolate and purify the constituents. Structural identification of isolated compounds was based on physical properties and spectroscopic analysis. RESULTS： A new methyl orsellinate glycoside, methyl 2-hydroxy-6-methyl benzoate 4-O-β-D-glucopyranoside （1） and a known methyl orsellinate （2） were isolated from this plant. CONCLUSION： A new compound is isolated, and this study enriches the chemical constituents of R.primulaeflorum.
