| Abstract: | Objective ] To study the antioxidant activity of volatile oil from leaves of Mentha haplocalyx Briq. Method ] The volatile oil from leaves of Mentha haplocalyx Briq. was extracted by steam distillation and its antioxidant activity was evaluated by total reducing power, scav- enging capacity against sodium nitrite and DPPH free radical. Result] The volumes of volatile oil was 332.08 μl when the absorbance was 0. 5, and the volumes of volatile oil was 85.85 and 99.33 μl when the scavenging rate against DPPH · and sodium nitrite of volatile oil was 50% in a concentration-dependent fashion. Conclusion] The volatile oil exhibited significant antioxidant activity. |
