Abstract
Commelina benghalensis L. commonly known as Benghal dayflower, belongs to the family Commelinaceae. Commelina benghalensis L. is a perennial herb native to tropical Asia and Africa. Valaiyans of Piranmalai hills, Tamilnadu used the leaves for the treatment of rabies and wounds [1, 2] The kavirajes tribals of Bangladesh used the young leaves for external poisoning . The litertature survey of phytochemical screening of Commelina benghalensis L revealed the presence of tannins, phlobatannins, saponins, flavonoids, alkaloids etc.,The hydroalcoholic extract (70%) of Commelina benghalensis L. (Leaf) was subjected to preliminary phytochemical studies and antioxidant activity. The phytochemical screening of the hydroalcoholic extract (70%) of Commelina benghalensis L. (Leaf) revealed the presence of alkaloids, carbohydrates, sterols, saponins, tannins and phenolic compound, flavonoids, protein and free aminoacid, terpenoids, mucilage, betacyanin, quinone, phlobatannins, carotenoids. The inhibitory concentration (IC50) of Commelina benghalensis L. (Leaf) against hydrogen peroxide scavenging effect was found to be 18 µg/mL in comparison with (ascorbic acid 7µg/mL). The inhibitory concentration (IC50) of Commelina benghalensis L. (Leaf) in reducing power assay is found to be 12 µg/mL in comparison with (ascorbic acid 9µg/mL). The total antioxidant capacity is found to be 40 µg/mL in comparison with (ascorbic acid 10 µg/mL). It showed mild to moderate anti oxidant effect when compared with ascorbic acid.
