Abstract: The appearance characteristics and main nutrients of nuts from five Ginkgo trees in Tuole Village in Panzhou City,Guizhou Province,China,were analyzed by the main component analysis. The results showed that the appearance characteristics of the nuts from five Ginkgo trees showed some differences,with variation between 3.960% and 19.992%,among which No. 4 was the one with the largest kernel weight. Ginkgo nuts were rich in nutrients,including protein(4.17%~5.47%),coarse fiber(1.10%~2.24%),total sugar(0.29%~0.73%),total acid(0.46%~0.55%),total flavonoids(0.014%~0.024%),vitamin C(22.7~36.0 mg/100 g),17 amino acids(32.19~52.44 g/100 g)and 9 mineral elements(480.17~620.27 mg/kg). Among the tested sample,the protein content in nuts of No. 4 was the highest(5.47%),whose total acids(0.54%)and total flavonoids(0.019%)were ranked as the 2^nd,and the total sugars(0.62%)and amino acid(38.50 g/kg)contents were ranked as the 3^rd. The main component analysis showed that the comprehensive scores of nut quality of the five Ginkgo trees(No. 1~No. 5)were -2.43,0.45,0.43,2.17 and -0.07,respectively,indicating the best comprehensive quality for Ginkgo tree No. 4.
