| Abstract: | Objective] The aim of the study was to determine the amino acid content in Jipi yam in Heze so as to provide scientific data for its resource development.Method] The tested Jipi yam was collected from the suburban countryside of Heze City in Shandong Province,it had long root with diameter of 1.6-2.9 cm.After the sample was treated by acid hydrolysis,its composition of amino acids was determined by amino acid analyzer.Result] Jipi yam in Heze contained 19 amino acids,with many kinds and the total content of 19 225.1 mg,including 8 essential amino acids being phenylalanine,methionine,lysine,leucine,tryptophan,threonine,valine and isoleucine,with total content of 6 763.0 mg and accounting for 35.18% of total amino acid content.It also contained the arginine and histidine,which were essential to baby,with their content of 3 688.5 mg and accounting for 19.19% of total amino acid.Conclusion] The total essential amino acid had higher proportion in Jipi yam in Heze,so it had very high study value in medical science and nutriology. |
