Abstract:
The present study was carried out to evaluate and find the extracts having good in-vitro antioxidant properties from Nyctanthes arbor-tristis L. (Parijat). An in-vitro free radical scavenging activity of the different extracts was using DPPH (1, 1-Diphenyl-2-picrylhydrazyl) method. Methanol, chloroform and aqueous extracts of plant were prepared by soxhlet extraction and used to evaluated antioxidant property. The different concentration of the extract (μg/mL) showed good free radical scavenging property which was calculated as a percentage inhibition. The results showed that highest percentage inhibition of the methanol, chloroform and aqueous extracts were found to be 66.38, 32.90 and 37.93 % at 50 μg.mL^−1 against DPPH activity, respectively. The extracts showed significant antioxidant activities compared to the ascorbic acid. Methanolic extract of N. arbor-tristis showed good inhibition when compared to the reference standard (P<0.05) which might be responsible due to high phenolic content in the leaf extract. It was concluded that methanol extract of N. arbor-tristis leaf exhibited potent free radical scavenging activity.
