Abstract:

         We determined and analyzed protein,total sugar,total acid,pectin, vitamin,amino acids,inorganic salt and mineral elements of 14 species of Chaenomeles speciosa Nakal. The content of their total sugar is in the range of 1.3~3.5 g/100 g; the content of their amino acid is rich and can reach 0.26 g/100 g~0.50 g/100 g; the content of their vitamin C is in the range of 68.8~159.3 mg/100 g, significantly higher than other common fruits. The content of their mineral elements is richhigher kalium and lower sodium. The content of these nutrient components in Jinbao is significantly superior to the other species. Experimental results show the content of nutrient components of Chaenomeles speciosa Nakal is rich and these fruits are worth being explored and utilized, especially for Jinbao.
