IN VITRO TOTAL PHENOLICS, FLAVONOIDS CONTENTS, ANTIOXIDANT AND ANTIMICROBIAL ACTIVITES OF VARIOUS SOLVENT EXTRACTS FROM THE MEDICINAL PLANT PHYSALIS MINIMA LINN
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2017, Vol 9, Issue 3
Abstract
Objective: To estimate the in vitro total phenolics, flavonoids contents, antioxidant and antimicrobial activities of various solvent extracts from the medicinal plant Physalis minima Linn.Methods: The crude bioactive were extracted from the dried powder of Physalis minima using methanol, ethyl acetate, chloroform and hexane solvents. Total phenolic content (TPC) and total flavonoid content (TFC) were estimated using Folin-Ciocalteu and aluminium chloride colorimetric methods respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and ferric reducing antioxidant power (FRAP) assays were used to determine the in vitro antioxidant capacity. The antimicrobial assay was done through agar well diffusion; minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined using broth microdilution methods against the Gram-negative bacteria (Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris) and Gram-positive bacteria (Staphylococcus aureus).Results: TPC expressed as gallic acid equivalents (GAE) ranged from 60.27±1.73-151.25±2.50 mg GAE/g dry weight, and TFC expressed as quercetin equivalents (QE) ranged from 56.66±0.80-158.84±2.30 mg QE/g dry weight. Methanol extract showed the highest antioxidant activity followed by ethyl acetate, chloroform, hexane extract and the IC50 values of methanol extract for scavenging DPPH and ABTS free radicals were 280.23±5.75-173.40±0.38µg/ml, respectively. All the extracts have shown potent antimicrobial activity for the zone of inhibition ranged from 9-35 mm; MICs and MBCs values ranged from 0.125-4.0 and 0.25-8.0 mg/ml, respectively towards tested pathogenic species.Conclusion: The comprehensive analysis of the present results demonstrated that Physalis minima possess high potential antioxidant properties which could be used as a viable source of natural antioxidants in treating infections caused by above-mentioned pathogens.
