Abstract
The chamomile Anthemis nobilis dried flowers was selected as experimental material, and the active ingredients of Anthemis nobilis were extracted with water to determine the ability to remove DPPH and study the antioxidant capacity of Anthemis nobilis aqueous extracts. Single factor variable method, orthogonal experimental method and response surface method were used to select the optimum time, temperature and material/liquid ratio of chamomile. It achieves the maximum DPPH clearance. The experimental results showed that the time was 140 min. Temperature is set to 30°C; when the ratio of feed to liquid was set at 1:20, the DPPH clearance rate of the effective components in Anthemis nobilis water immersion solution reached a maximum of 96.79%.
