Analysis and Evaluation of Nutritional Composition and Bioactive Composition in Chinese Wolfberry (Lycium barbarum L.) Fruits from Different Regions of Qinghai Province

Abstract

Abstract: In this study we report the results of a comparative study on quality characteristics of Chinese wolfberries from 12 different regions of Qinghai province. Chinese wolfberries were determined by national standard methods and previously reported methods for proximate nutritional composition and by pre-column derivatization with DBCEC-Cl and high-performance liquid chromatography with fluorescence detection (HPLC-FLD) for amino acid contents. Besides, we measured the contents of polysaccharides and flavonoids. The results show that Chinese wolfberries grown in Qinghai province contained abundant nutrients, a complete range of amino acids with a reasonable blend, relatively high amounts of polysacchadrides and flavonoids, suggesting great development potential.

Key words: Lycium barbarum L., nutritional composition, bioactive composition, HPLC with fluorescence detection, amino acid, nutritional evaluation
