Abstract: To study the antioxidant activity of the ethanol extraction of Pyrrosia petiolosa, DPPH radical scavenging, reducing power, total antioxidant activity and hydroxyl radical scavenging assay were determined. The results showed that the IC50 of the DPPH· and ·OH radical scavenging were 75.82 and 46.30 μg·mL-1, respectively. Compared with the ascorbic acid, the ability of DPPH free radical scavenging was higher, while the ·OH radical scavenging activity was lower. It indicated that the ethanol extraction of P. petiolosa had strong antioxidant activity.

Key words: Pyrrosia petiolosa, alcohol extract, antioxidant activity

摘要: 通过DPPH自由基清除测定、还原能力、总抗氧化能力、羟自由基清除测定,评价有柄石韦Pyrrosia petiolosa醇提物的抗氧化活性。结果显示,有柄石韦醇提物清除DPPH·的IC50为75.82 μg·mL-1,清除·OH的IC50为46.30 μg·mL-1。有柄石韦醇提物清除DPPH· 的能力强于抗坏血酸,清除·OH的能力弱于抗坏血酸;同时,其还原能力和总抗氧化能力均强于抗坏血酸。该结果说明有柄石韦醇提物具有较强的抗氧化活性。
