Abstract：In the present study, the contents of nutritional elements such as Ca, Mg, K, Zn, Fe and Mn and heavy elements such as Cu, Cd and Pb in organic and traditional cherry tomato fruit were analyzed by ICP-OES, and the contents of some nutritional ingredients such as water, total soluble solid, soluble sugar and asorbic acid were also investigated. The results showed that the contents of K, Ca and Zn in organic cherry tomato were 1.62, 71.7 and 1.34 mg·g-1, which were 4.52%, 129.81% and 65.43% respectively higher than those in traditional tomato. There were no significant differences in the contents of Mg and Fe, which showed 73.8 and 2.05 mg·g-1 in organic cherry tomato. But the content of Mn in organic tomato was 0.475 mg·g-1, 11.22% lower than that in traditional one (α=0.05). The contents of Cu, Cd and Pb showed no significant differences in the two kinds of tomato, which were 0.457 mg·g-1, 4.86 ng·g-1 and 0.127 mg·g-1 respectively in organic cherry tomato, and all the contents were lower than the national requirement. There were no significant differences in the contents of water, soluble sugar, and asorbic acid, but the total soluble solid and the content of soluble protein were significantly higher in organic cherry tomato. The differences in the nutritional ingredients and mineral elements and safety status in the two kinds of tomato provide academic data for the evaluation of organic vegetables and traditional ones.
