RESUMO
Objective:To analyze the liposoluble components and antioxidant capacity of Caryopteris tangutica. Methods:By using GC-MS, this paper analyzes liposoluble components of different positions of Caryopteris tangutica. By making the removal rate of free radicals with liposoluble components as the index, and making IC 50 as reference indicators to evaluate the antioxidant capacity of lipidsoluble extracts of different parts. Results:There are 31, 40 and 62 compounds identified in the liposoluble components of the stems, leaves and flower, among which unsaturated fatty acids account for the most. The different parts of Caryopteris tangutica all play the role of clearing DPPH and ABTS + free radicals, and the clearing rate of leaves was greater than that of flowers and stems. Conclusion:The unsaturated fatty acids in lipidsoluble components of Caryopteris tangutica are beneficial to the human body, and have antioxidant activity.
