Establishment of Amino Acid Map Database of Eriocheir sinensis in Jiangsu and Zhejiang Provinces
[Objective]To study the difference of amino acid composition of Eriocheir sinensis from different habitats(Yangcheng Lake,Taihu Lake,Hongze Lake and Gucheng Lake)in Jiangsu and Zhejiang provinces.With advanced chemometrics analysis,an amino acid map database for identifying Eriocheir sinensis from different habitats was established.[Method]The sample was hydrolyzed by hydrochloric acid,purified and then determined the amino acid composition in the sample by amino acid analyzer.ChemPattern software was used to make chemometric analy-sis on amino acid profiles of Eriocheir sinensis from different habitats,and a recognition model was established.[Result]The amino acid compo-sition of Eriocheir sinensis in Yangcheng Lake,Taihu Lake,Hongze Lake and Gucheng Lake was significantly different.We established a sample classification and identification model to accurately identify Eriocheir sinensis from different habitats.[Conclusion]The identification system of Eriocheir sinensis from different habitats(Yangcheng Lake,Taihu Lake,Hongze Lake and Gucheng Lake)established in this paper has the ad-vantages of simplicity,stability,accuracy and good reproducibility.It could provide a scientific scheme for the origin discrimination of Eriocheir sinensis in Jiangsu and Zhejiang provinces.
