浙贝母花的氨基酸成分分析

目的]测定浙贝母花中氨基酸的种类和含量,为浙贝母花的资源开发提供科学依据。方法]以采摘后自然阴干,冷冻干燥的和流化床干燥的浙贝母花作为研究对象,采用茚三酮柱后衍生-氨基酸分析法,测定3种处理下的浙贝母花的氨基酸含量。结果]共测出17种氨基酸,并且氨基酸的总量在3种处理的浙贝母花中均高达200g/kg,其中谷氨酸含量最高,7种人体必需氨基酸均占所测氨基酸总量30.0%以上。结论]浙贝母花及其相关产物具有较高的药用价值和保健价值,值得进一步开发。

Analysis of Amino Acids in the Flowers of Fritillaria thunbergii Miq

Objective] To determine the types and contents of amino acids in the flowers of Fritilaria thunbergii Miq.,so as to provide scientific basis for its further development.Method] Natural dried,lyophilized and fluidized bed treated flowers of Fritillaria thunbergii Miq.were as test materials,and the content of amino acids in which were determined by ninhydrin column derivatization method.Result] There were 17 types of amino acids in the flower of Fritillaria thunbergii Miq.,and the total contents of amino acids in different treated Fritillaria thunbergii Miq.flowers achieved 200 g/kg,among which the content of glutamic acid was the highest,and the essential amino acids accounted for more than 30.0% in total. Conclusion] The flowers of Fritillaria thunbergii Miq.were endowed with high medical and healthy value,which deserve further research.
