Abstract: To solve the problem that consumers' consumption of fresh and produced Rosa roxburghii Tratt, as well as obtain nutrition and so on, using fresh and vary degrees dried Rosa roxburghii Tratt as test material, so that applying the method of data comparison to study vitamin C and SOD. This paper used the method of thorn spectrophotometer pear to determine of the Vc value and the SOD activity in different moisture content of Rosa roxburghii Tratt. The determination of Vc value was compared with apple and kiwi. The result indicated fresh Rosa roxburghii Tratt content in 1900-2200 mgVc/(100 g·FW), which was 46-53 times of the apple, and 14-17 times as much as kiwi. When the moisture content of Rosa roxburghii Tratt fell to 60%, the Vc value proved a significant decrease. Similarly, when the moisture content dropped below 75% until fully dry state, SOD activity showed a maximum loss. This paper could make guidance to people’s diet.
