ABSTRACT:
The objective of this study was to evaluate the phytochemical composition and antioxidant activity of Barleria mysorensis L. (Acanthaceae) and Furcraea foetida L. (Agavaceae) leaves. Aqueous extract of B. mysorensis and F. foetida leaves were screened for the presence of major phytochemical groups by various biochemical methods. Phytochemical screening of the plant extracts confirmed the presence of tannins, phenolic compounds, saponins, flavanoid and phytosterols in both the extracts, although carbohydrates were present only in F. foetida. Antioxidant activity of extracts was performed by in vitro methods, such as 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and metal chelating activity. Total phenolic content was estimated by Folin-Ciocalteau reagent method. Both extracts execute effective antioxidant activity in both the assay, however, F. foetida exhibit significantlt (p < 0.05) high activity than B. mysorensis. Analysis of total phenolic content in both the extracts exhibited the presence of significant amount of phenolic compounds which could possibly be the reason for antioxidant potential of the tested plants. The results suggest possible use of B. mysorensis and F. foetida for the development of highly potent, safe and novel antioxidant compounds.
