The results showed that the highest contents of soluble sugar and protein were both in the fruit of Jishou, 5.47% and 7.13% respectively . The contents of crude fiber produced in the fruit of Fenghuang County were greater than that of the other two places, reached to 5.86%. Yongshun County was found to have the fruit of the richest contents of Vc, reached to 43.49% mg/100g.
