摘要
目的:对构树枝条的化学成分进行分离和鉴定。方法:使用硅胶、Sephadex LH-20反复柱色谱分离、纯化,利用ESI-MS和NMB技术确定结构。结果:分离鉴定了6个化合物,分别为(2S)-7,3'-dihydmxy-4'-methoxyflavan(1),过氧化麦角甾醇(ergosterol peroxide,2),D-半乳糖醇(D-galacitol,3),sulfurefin(4),黑立脂素苷(liriodendrin,5),graveolone(6)。结论:化合物1~6均为首次从构树中分离得到。
Objective: To investigate the chemical constituents from the branch of Broussonetia papyrifera. Method: Column chromatographic methods were used to isolate the chemical constituents. ESI-MS and NMR methods were employed for their structural elucidation. Result: Six compounds were isolated and identified as (2S)-7, 3'-dihydroxy-4'-methoxyflavan (1), ergosterol peroxide (2), D-galacitol (3), sulfuretin (4), liriedendrin (5), graveolone (6), respectively. Conclusion: Compounds 1-6 were isolated from the plant for the first time.
