OBJECTIVE
To investigate the chemical constituents of Ipomoea batatas.
METHODS
Silica gel column chromatography and Sephadex LH-20 were used to separate and purify the compounds from the EtOAc and n-BuOH soluble fraction of ethanol extracts. The chemical structures were elucidated on the basis of physic-chemical properties and spectral data.
RESULTS
Four compounds were isolated and identify as citrusin C (1), caffeicacid (2), 3,4-di-O-caffeoylquinic acid (3), 1,2,3,4-tetrahydro-beta-carboline-3-carboylic acid (4).
CONCLUSION
Compounds 1-4 are isolated for the first time from I. batatas.
目的
研究甘薯的化学成分。
方法
采用硅胶柱色谱和葡聚糖凝胶LH - 20从乙醇提取物的乙酸乙酯和正丁醇可溶部分中分离纯化化合物。根据理化性质和光谱数据阐明化学结构。
结果
分离得到4个化合物，分别鉴定为柑橘素C（1）、咖啡酸（2）、3,4 - 二 - O - 咖啡酰奎宁酸（3）、1,2,3,4 - 四氢 - β - 咔啉 - 3 - 羧酸（4）。
结论
化合物1 - 4首次从甘薯中分离得到。
