摘要：The aim of the present paper was to investigate the antioxidant capacity and the possible cell structure changes of frozen Chrysanthemum balsamita leaves. The antioxidant activity of the studied aqueous extracts was estimated through ABTS, DPPH, FRAP, and CUPRAC methods. The total phenolic content was assessed as well. The results varied significantly before and after freezing of the plant samples. The total phenolic content of the fresh leaves was established to be 0.59 mg GAE/g PW and 0.68 mg GAE/g PW of the frozen leaves.The microscopic analysis of both fresh and frozen leaves showed changes in the cellular structure which influenced the radical scavenging activity of the frozen Chrysanthemum balsamita plant samples
