目的:对栾树花进行化学成分研究。方法:采用硅胶、聚酰胺柱层析进行分离纯化,根据理化性质和光谱分析鉴定化合物结构。结果:从栾树花乙酸乙酯部位中分离得到9个化合物,经鉴定分别为:胡萝卜苷(Ⅰ)、没食子酸(Ⅱ)、山柰酚(Ⅲ)、木犀草素(Ⅳ)、山柰素-3-O-(6″-乙酰基)-β-D-葡萄糖苷(Ⅴ)、2″-O-乙酰基金丝桃苷(Ⅵ)、2″-O-没食子酰基金丝桃苷(Ⅶ)、金丝桃苷(Ⅷ)、山柰酚-3-O-β-D-葡萄糖苷(Ⅸ)。结论:9个化合物均为首次从栾树花中分离得到;化合物Ⅳ、Ⅴ、Ⅵ和Ⅸ为首次从该属植物中分离得到。
Objective: To study the chemical constituents of Methods: The compounds were isolated and purified by silica gel and polyamide column chromatography. The structures of compounds were identified by their physicochemical properties and spectral analysis. Results: Nine compounds were isolated from the ethyl acetate fraction of LARs. The compounds were identified as daucosterol (Ⅰ), gallic acid (Ⅱ), kaempferol (Ⅲ), luteolin (Ⅳ) -O-acetylglucoside (Ⅵ), 2 “-O-galloyl glucoside (Ⅶ), 2” -O-acetylglucoside (Ⅷ), kaempferol-3-O-β-D-glucoside (Ⅸ) .CONCLUSION: Nine compounds were isolated from the flower of Koelreuteria for the first time. The compounds Ⅳ, Ⅴ, Ⅵ and Ⅸ was isolated from the genus for the first time.
