Objective To explore the antioxidant effect of Ginkgo biloba vinegar. Methods 68 patients with hypertension, hyperlipidemia and angina pectoris were treated with 50ml three times a day after meals for 65 438 0 months. Observe the plasma vitamin C(P-Vc), vitamin E(P-VE), β-carotene (P-β-CAR), plasma lipid peroxide (P-LPO), erythrocyte superoxide dismutase (E-SOD), catalase (E-CAT) and glutathione peroxidase (E-GSH) before and after drinking Ginkgo vinegar. After drinking, the average values of P-Vc, P-VE, P-β-CAR, E-SOD, E-CAT and E-GSH-PX all increased significantly (P < 0.0 1), while the average values of P-LPO and E-LPO all decreased significantly (P < 0.0 1).
