| description | Background: Averrhoa bilimbi, Gymnema sylvestre and Capsicum frutescens are medicinal
plants commonly used as traditional medicine for the treatment of various diseases. The present
study was designed to investigate the antioxidant activities of Ethanolic extract of A. bilimbi,
G. sylvestre and C. frutescens. Materials and Methods: The antioxidant activity of the extracts
were evaluated using total phenolic and fl avonoid contents, ferric reducing power and the
free radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH). Results: Total
phenolic and fl avonoid contents were higher in G. sylvestre (53.63636 ± 0.454545 mg/g
gallic acid equivalent) and C. frutescens (26.66667 ± 2.081666 mg/g quercetin equivalent)
respectively. Reducing power of the crude ethanol extracts increased with the concentrations
of the extracts and all the extracts showed moderate free radical scavenging activity against
DPPH. The plant extract displayed moderate phenolic and fl avonoid contents compared to
gallic acid and quercetin equivalent respectively, whereas also exhibited signifi cant scavenging
of DPPH radical and reducing power compared with ascorbic acid as standard. Conclusion:
Our study suggests that G. sylvestre has signifi cant antioxidant activity. The antioxidant
compound of this plant might be a therapeutic candidate against oxidative stress related
diseases. Different sub-fraction of A. bilimbi and C. frutescens should be studied further to
assess the effect. Further study is necessary for isolation and characterization of the active
antioxidant agents for better treatment. |
