PHYTOCHEMICAL SCREENING, ANTIOXIDANT PROPERTIES IN VARIOUS EXTRACTS FROM THE LEAVES OF FLAGELLARIA INDICA L. FROM SABAH, MALAYSIA
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 9
Abstract
Objective: This study was conducted to evaluate the antioxidant capacities of the leaves of Flagellaria indica L. (FI) and its phytochemical constituents in six different extracts.Methods: The assessment was done via a 2,2-diphenyl-1-picryl hydrazyl (DPPH) radical scavenging assay for the antioxidant test, the Folin-ciocalteau method for total phenolic content, Willet’s method for total flavonoid content and several other qualitative phytochemical tests carried out on all extracts.Results: The results show the highest values of radical scavenging in the following order of extracts: butanol>ethyl acetate>aqueous>chloroform>methanol>hexane. The total phenolic content is the highest in the ethyl acetate (e. acetate) extract (153.28 mg/g) followed by butanol (134.78 mg/g), aqueous extract (65.88 mg/g), chloroform (55.28 mg/g), methanol (45.98 mg/g) and hexane (22.78 mg/g), expressed as gallic acid equivalents. The total flavonoids content was also the highest in e. acetate extract (38.96 mg/g) followed by butanol (28.45 mg/g), aqueous (21.18 mg/g), chloroform (12.9 mg/g), methanol (10.78 mg/g) and hexane extract (4.92 mg/g) using cathechin equivalents.Conclusion: The antioxidant and radical scavenging activities of FI might be due to the strong presence of phenolic constituents, flavonoids and several other bioactive compounds. Thus, further research can be conducted to elucidate the potential of this plant for pharmacological importance.Â
