基于NMR代谢组学技术对山药化学成分的研究

摘要

试验采用基于NMR代谢组学的技术，分别对生山药饮片、麸炒山药及食用山药的化学成分进行了研究，检测出30多种化合物，包括腺苷、胆碱、多种氨基酸、有机酸及糖类等物质，其中有14种是3种山药的共有成分。另外，对引起生山药与麸炒山药、食用山药与药用山药差异的化学成分进行了指认，初步了解了炮制对山药化学成分的影响及山药药材与食材的差异。%The studies on chemical constituents of dried yam slices, bran fried yam and edible yam were carried out re-spectively by means of 1HNMR-based metabolomics. Over thirty compounds including adenosine, choline, amino acids, organic acids, sugars and other substances were detected, of which fourteen were common components in three kinds of yams. Their respective characteristic chemical compositions were indicated. Effect of processing on the chemical compo-nents of yam and the differences between edible yam and dried yam slices, bran fried yam were reviewed.
