Phytochemical screening, total phenolic and flavonoid contents and antioxidant activity of Anabasis setifera and Salsola tomentosa extracted with different extraction methods and solvents

Abstract

In this study, the tests of phytochemical screening included phenols, tannins, flavonoids and saponins. Total phenolic was estimated by the Foline–Ciocalteu method, total flavonoid content was determined by a colorimetric method. Extracts were also monitored on their antioxidant ability by DPPH and β-carotene bleaching methods. The phytochemical screening of A. setifera and S. tomentosa dry aerial parts revealed the presence of phenolic components (tannins, flavonoids and total phenols), and saponins. Total phenolic and flavonoid were high with methanol extraction whereas acetone showed poor flavonoid and polyphenol continent in both soxhlet apparatus and maceration methods. Furthermore all the extracts have good antioxidant activities. This work will be helpful to explore the biochemical profile and active compound identification in the field of pharmaceutical research.
