Physico-Chemical Constant, Phytochemical Screening and Antioxidant Activity of Different Extracts of Commelina clavata

摘要

The present study was designed to phytochemically screen different extracts of the whole plant of Commelina clavata (Commelinaceae), a plant generally used in the cure of pain and to establish physicochemical constants and in vitro antioxidant activity of these extracts. A physicochemical evaluation was carried out by assessing ash, alcohol and water-soluble extraction values: 5.35, 2.70 and 3.10% (w/w), respectively. Carbohydrates, tannins, alkaloids and flavonoids were present. The ethanolic extract showed potent antioxidant activity, assessed by in vitro methods (reducing power and hydrogen peroxide scavenging methods).
