OBJECTIVE: To study the leaves of Adiantum philippense L. for their antioxidant, cytotoxicity and thrombolytic activities and to perform phytochemical evaluation. METHODS: In-vitro antioxidant activity of extract was studied using DPPH radical scavenging, reducing power, total phenol and total flavonoid content determination assays. The cytotoxic activity was determined using brine shrimp lethality bioassay, thrombolytic activity by clot disruption and phytochemical potential by qualitative analysis. RESULTS: The antioxidant activity of the extracts was found promising. The reducing power of this crude extract increase with the increase of concentration; IC50 values of DPPH scavenging activity was (140.00±0.86) µg/mL as compared to ascorbic acid [IC50 (130.00±0.76) µg/mL]; Total phenol and total flavonoids content were (148.26±0.24) mg/mL and (163.06±0.56) mg/mL respectively. In cytotoxicity assay the LC50 values of the sample was (106.41±0.78) µg/mL where as for standard vincristin sulphate was (08.50±0.24) µg/mL as a positive control and the extract shows (12.86±1.02)% clot lytic whereas standard streptokinase shows (30.86±0.44% clot lytic activity in thrombolytic assay. The phytochemical evaluation indicates the presence of chemical constituents including carbohydrates, alkaloids, saponins, glycosides, flavonoids. CONCLUSIONS: This study shows that the methanol extract of leaves of Adiantum philippense L. has bioactivity but further compound isolation is necessary to confirm the activities of individual compounds.
