Components Analysis of Amino Acids and Mineral Elements in Rhizome of Dioscorea Cirrhosa Lour.
摘要
Abstract
[ Objective] To analyze and determine the compositions of amino acids and mineral elements in Rhizoma Dioscorea Cirrhosae tuber,so as to provide theoretical evidence for the development of rhizome of Dioscorea cirrhosa Lout. [ Method ] Contents of amino acids were determined by high-performance liquid chromatography and that of mineral elements were determined by inductively coupled plasma mass spectrometry. [ Result ] Sixteen amino acids were obtained and lowest in methianine,the content of essential amino acids was 37.98％ ,of which the content of as partic acid,glutamic acid and leucine ranked the first,second and third respectively. Dioscorea cirrhosa Lour. tuber were rich in five constant elements K,Ca,Na, P and Mg as well as fourteen trace elements B, Mn, Mo, Co, Ni, Cr, Cu, Se, Fe, Sr, Zn, Ba, Cd and Li. [ Conclusion ] Dioscorea cirrhosa Lour. tuber are rich in plenty of nutrient components and pharmacodynamic elements, and this case provides theoretical evidence for the development of Dioscorea cirrhosa Lour. tuber.关键词
