BHT和GBE（P<0.05）。 The extracting technology and antioxidant activities of lotus leaf were studied. The results showed that the optimal parameters of the extracting technology were the extracting time was 50min, the extracting temperature was 80℃, the concentration of ethanol was 60% and the ratio of sample to extracting solution was 1∶20. The ethyl acetate fraction possessed the strongest antioxidant activities (P<0.001or P<0.01), i. e., the reducing power, FRAP value and DPPH radicals scavenging capacity among the four increasing polar fractions (hexane, ethyl acetate, butanol and aqueous fractions) through the bio-assay guided method. The OD593 values and DPPH radicals scavenging capacities of this fraction were better than those of the positive controls of BHT and GBE (P<0.05) through the experiments of verification. 
