Abstract: In order to systematically analyze and evaluate fruit nutritional qualities of different Phyllanthus emblica varieties, ‘Chipi’, ‘Boliyougan’, ‘Dongkengtian’, ‘Bingtian’, ‘Liuyuebai’ and ‘Matitian’ were used as materials. Seven nutrient contents were analyzed and evaluated by the principal component analysis method. The results showed that the contents of vitamin C and reducing sugars in each cultivar were relatively high; Vitamin C had a significant positive correlation with protein, and reducing sugar had a significant positive correlation with soluble solids. Three principal components were extracted through principal component analysis. Two varieties, ‘Chipi’ and ‘Boliyougan’, with higher comprehensive nutrients were screened out as excellent varieties for the construction of P. emblica high-yield forests.
