摘要

The chemical composition and nutritional value of Tomentosa Cherry (Prunus tomentosa Thunb.) Fruit were determined and evaluated. The fruit contains sorts of vitamins, such as carotene, Vm, VB:, Vc, VD, Vpp, and VE etc. Mineral elements and trace elements content of Ca, P, Fe etc. are higher than other fruit, obviously. Among them, Vc and Ca content are high (63.5mg/l00g and 1.607mg/g) which were 2-30 times and 10-80 times of general fruit, respectively. Tomentosa Cherry (Prunus tomentosa Thunb.) fruit contains 17 sorts of amino acids. Essential amino acids account for 979.9mg/100g, making up of 49.2% of the total amino acids (1992.5mg/g). On the other hand, the resource conservation, product research and utilization of Tomentosa cherry were discussed.
