摘要(Abstract):

目的:研究秀雅杜鹃的化学成分。方法:利用硅胶色谱和聚酰胺色谱技术分离纯化,通过理化性质和波谱方法鉴定化合物的结构。结果:从秀雅杜鹃的乙酸乙酯部分分离鉴定了5个二氢黄酮类化合物,分别鉴定为(2R)-杜鹃素-7-O-β-D-葡萄糖苷(1),(2R,3R)-(-)-二氢槲皮素-3-O-β-D-木糖苷(2),(2S,3S)-(-)-二氢槲皮素-3-O-β-D-葡萄糖苷(3),北美圣草素-7-O-β-D-葡萄糖苷(4),(2R,3R)-(+)-二氢槲皮素(5)。结论:除化合物5外,其余化合物均为首次从该属植物中分离得到。
Objective: To study the chemical constituents of the whole plant of Rhododendron concinnum.Method: The compounds were isolated and purified by chromatography on silica gel and polyamide.Their structures were identified on the basis of spectroscopic data(MS,1H-NMR and 13C-NMR) and chemical evidence.Result: Five dihydroflavones were isolated and identified as(2R)-farrerol-7-O-glucopyranoside(1),(2R,3R)-(-)-dihydroquercetin-3-O-β-D-xylopyranoside(2),(2S,3S)-(-)-dihydroquercetin-3-O-β-D-glucopyranoside(3),eriodictyol-7-O-β-D-glucopyranoside(4),(2R,3R)-(+)-dihydroquercetin(5).Conclusion: Except compound 5,others were firstly isolated from the genus Rhododendron.
