Comparison of Amino Acids and Volatile Constituents in Four Kinds of Dendrobium Flowers
摘要
Abstract
Objective:In order to analyze the amino acid composition and the volatile constituents from flower of Dendrobium nobile,D.chrysotoxum,D.officinale and D.devonianum.Methods:The amino acid composition in Dendrobium flowers were measured by amino acid analyzer,and the relevant non-biological indexes were used to evaluate the nutritional values.The volatile constituents were analyzed by GC-MS,and the relative percentage of the oil constituents was calculated from the GC peak areas.Results:The four kinds of Dendrobium flowers contained 7 essential amino acids(EAA).In addition to the D.chrysotoxum flower,the three other dendrobium flowers are ideal for the ideal protein.The total scores of the AAS and CS scores of the three kinds of dendrobium were closer to 1,but the difference was not significant.And SRC(D.nobile)> SRC (D.devonianum)> SRC(D.officinale)> SRC(D.chrysotoxum).The results showed that the nutritional value of D.nobile flower was the highest,and D.devonianum flower and D.officinale flower was similar,and D.chrysotoxum flower was the low-est.A total of 37,31,26,21 compounds were identified from the volatile components of D.devonianum flower, D.chrysotoxum flower,D.officinale flower and D.nobile flower,of which representing 53.44%,61.74%,73.72%, 63.17% of the oil were characterized.The volatile constituents of four kinds of Dendrobium flowers were mainly aldehydes,al-kanes,esters,alcohols and nitrogen compounds,which D.nobile flower was more obvious differences than the other three.Conclusion:The nutritive value of D.nobile flower is higher than that of the other Dendrobium flowers.The volatile com-ponents in four kinds of Dendrobium flowers are different.Some volatile constituents contain aroma and rich pharmacological ac-tivity,which can a scientific basis for the further development and utilization of Dendrobium flowers.关键词
