目的:对药材桃儿七的化学成分进行研究。方法:利用大孔吸附树脂柱色谱、Sephadex LH-20柱色谱、ODS柱色谱、硅胶柱色谱进行分离纯化,通过理化常数和波谱分析技术进行结构鉴定。结果:从桃儿七中分离得到9个化合物,分别鉴定为:异苦去氧鬼臼毒素(Ⅰ)、3β-羟基-7α-甲氧基-24β-乙基-胆甾-5-烯(Ⅱ)、5α,8α-过氧-(22E,24R)-麦角甾-6,22-二烯-3β-醇(Ⅲ)、7β-羟基-谷甾醇(Ⅳ)、β-谷甾醇(Ⅴ)、胡萝卜苷(Ⅵ)、α-棕榈酸甘油酯(Ⅶ)、α-D-葡萄糖(Ⅷ)、5-羟甲基糠醛(Ⅸ)。结论:化合物Ⅰ～Ⅳ、Ⅶ～Ⅸ为首次从该属植物中分离得到。
Objective: To study the chemical constituents of Peach seven. Methods: Macroporous resin column chromatography, Sephadex LH-20 column chromatography, ODS column chromatography and silica gel column chromatography were used for the isolation and purification. The structures were elucidated by physicochemical constants and spectral analysis techniques. Results: Nine compounds were isolated from Peach seven, identified as: dehydroepiandotoxin (Ⅰ), 3β-hydroxy-7α-methoxy-24β-ethyl-cholest- (Ⅲ), 7β-hydroxy-sitosterol (Ⅳ), β-sitosterol (Ⅴ), 5α, 8α-peroxo- (Ⅵ), α-palmitic acid (Ⅶ), α-D-glucose (Ⅷ) and 5-hydroxymethylfurfural (Ⅸ). Conclusion: Compounds Ⅰ ~ Ⅳ, Ⅶ ~ Ⅸ were isolated from this genus for the first time.
