The ethanol, methanol, and acetone extracts of different parts of Impatiens balsamina L. were prepared and evaluated for anti-tyrosinase and antioxidant activities. Among the solvents of extraction, methanol was the most potent solvent. The tyrosinase inhibition assay suggested that the flower extracts have an anti-tyrosinase activity that was about 50% in relation to copper-chelating activity and better than leaves and stems extracts. Total phenolic and flavonoid contents found in the methanol flower extracts were 1,596.08±38.59 mg gallic acid equivalent g-1 and 884.83±1.34 mg quercetin equivalent g-1 , respectively, which were much more than the leaves and stems. The total phenolic and flavonoid contents possessed the anti-tyrosinase activity with r=0.632 and 0.542, respectively. Nevertheless, the flower extract exhibited the greatest amount of antioxidant activity. In conclusion, the flower extract of I. balsamina could serve as a natural anti-tyrosinase compound to promote antioxidant activities and can be developed for further applications. |
