In Vitro, Antioxidant Activity of Various Leaves Extract of Hibiscus syriacus L.

The object of this study is to investigate the antioxidant potency of Hibiscus syriacus L. leaves extract with different solvent like petroleum ether, benzene, chloroform, methanol, and water. The phytochemical screening was identified the bioactive compounds in the extract. Methanolic extract of Hibiscus syriacus L. having higher amount of total phenolic contents compare to other extracts. As it is Methanolic extract of Hibiscus syriacus L. also having higher amount of total flavonoids contents compare to other extracts.of same plant leaves We assayed in vitro total antioxidant capacity of Hibiscus syriacus L. extract using ascorbic acid as references. Hibiscus syriacus L. extract have stronger antioxidant capacity on concentration dependent manner. Antioxidant activities of Hibiscus syriacus L. was very closed to the ascorbic acid. So, we can conclude that the in vitro study emphasized Hibiscus syriacus L. effective antioxidant and scavenging activities which may be due to its phenolics and flavonoids contents.
