本研究采用 2,2-二苯基-1-三硝基苯肼法（DPPH 测定）、铁还原抗氧化能力（FRAP 测定）和 β-胡萝卜素-亚油酸法评估 Pereskia bleo 叶的乙醇、乙酸乙酯、甲醇和己烷提取物的抗氧化特性。分别采用 Folin-Ciocalteu 法和 HPLC 法测定了 P. bleo 叶中的总酚化合物 (TPC) 和黄酮类化合物。本研究结果表明，P. bleo 叶的乙酸乙酯提取物表现出显着的 (p
The present study was conducted to assess the antioxidant properties of ethanol, ethyl acetate, methanol and hexane extracts from leaves of Pereskia bleo using 2,2-diphenyl-1-picrylhydrazyl method (DPPH assay), ferric reducing antioxidant power (FRAP assay) and beta-Carotene-Linoleic acid methods. Total phenolic compounds (TPC) and flavonoids of the leaves of P. bleo were measured using Folin-Ciocalteu and HPLC methods respectively. Results of the present study showed that Ethyl acetate extract of P. bleo leaf exhibited significantly (p
