Abstract

Using spectrophotometry,Oxford cup and two-fold dilution methods were adopted to study the antioxidant capacity,antimicrobial capability and anti-inflammatory capability of total flavonoids from Carica Papaya L.Leaves.The results showed that total flavonoids from Carica Papaya L.Leaves had great capability on antioxidant,antimicrobial and anti-inflammatory.It had stronger reducing capability than VC and BHT at the same concentration.And the MIC of the extracts on E.coli,S.aureus and Bacillus subtilis were 8,4 and 4 mg/mL,respectively.And the MBC on E.coli,S.aureus and Bacillus subtilis was 8,4 and 4 mg/mL,respectively.The IC50 of anti-inflammatory capability was 1.93mg/mL.
