摘要
为更好的了解紫薯的营养价值,采用高速逆流色谱法分离紫薯的乙酸乙酯萃取物,并通过1H NMR、13CNMR、ESI-MS和元素分析对分离得到的单体结构鉴定,得到两种功能性成分咖啡酸甲酯和咖啡酸乙酯。
The two functional components including methyl caffeate and ethyl caffeate in purple sweet potato were obtained sequentially by extraction with hot ethanol,reextraction with ethyl acetate and high-speed countercurrent chromatographic（HSCCC） separation.The two compounds were identified by 1H NMR,13C NMR,ESI-MS and element analysis.
