Antimutagenic and antioxidant characteristics of Chukrasia tabularis A Juss extracts.
The current study aims to evaluate the antioxidative and antimutagenic activities of methanol extract and different fractions of Chukrasia tabularis leaves. The antioxidative potential was evaluated using 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) cation and superoxide anion radical-scavenging assay. The antimutagenic potential was evaluated against direct-acting mutagens, 4-nitro-o-phenylenediamine and sodium azide; and S9-dependent mutagen, 2-aminofluorene in TA98 and TA100 strains of Salmonella typhimurium using Ames assay. It has been found that methanol extract and its fractions were more efficient against S9-dependent mutagen in pre-incubation mode of treatment as compared to direct-acting mutagens in both the strains. Methanol extract and its fractions also exhibited strong radical-scavenging potential. High-performance liquid chromatography (HPLC) analysis of methanol extract showed the presence of gallic acid, epicatechin, 7-hydroxycoumarin, and rutin. From the study, it could be concluded that antioxidative and antimutagenic activity of methanol extract and its fractions was related to the synergistic interactions among different chemical compounds.
