Abstract
A medicinal plant veronica genus has 450 well known species and found across both temperate and hemisphere region their 26 species are endemic and known in a total of 79 popular species and are widely utilized throughout the world due to important biological activities. In this study fully powdered uniform size specie veronica biloba plant taken in porous bag were manually subjected to soxhlet hot continuous process for cyclization of extraction using ethanol (300 mL) a concentrated dried extract obtained after solvent evaporation. Furthermore, liquid-liquid extracted fractions as water, dichloromethane, n-hexane, and ethyl acetate yields results found polar fraction with the highest percentage (water 47.51 %). The phytochemical screening of veronica biloba has shown all major compounds entirely present in extracts. One of the primitive phenolic compound flavonoid is present in plant and show potency towards antioxidants. All the extracted fractions of plant showed excellent antioxidant activity using a stable DPPH (1,1-diphenyl-2-picryl-hydrazyl) method at concentration (range from 31.25 to 500µg/mL). Primary our ethyl acetate extract fraction showed the highest inhibition potential at IC50 = 1.70±0.05µg/mL which is much closer to a standard positive control Propyl gallate showed IC50 = 1.6±0.05µg/mL percent potential. The purification and isolation of these extract areimportant which can provide us help in novel antioxidants discovery also natural antioxidants currently in cosmetics products, food and therapeutics health related products significantly demanded because they are very effective, efficient and harmless as compared to synthetic.
