Author(s): N. S. Rajurkar and Kunda GaikwadThe Adiantum capillus veneris was screened for phytochemicals and metal content. The antioxidant activity was also determined by different methods. It was observed that it contains 8.3 % moisture, 11.44 % ethanol extractable matter and 24.00 % water extractable matter. The soxhlet extraction of Adiantum capillus veneris showed the presence of phenolics and terpenoids (2.73 %), fats and waxes (0.20 %), alkaloids (0.53 %), quaternary and Noxides (26.33 %) and fiber (67.23 %). Ten elements Mg, Ca, K, Mn, Fe, Co, Na, Ni, Cu, and Zn were determined from plant sample using inductively coupled plasma atomic emission spectroscopy (ICP-AES) technique among which Ca and K were found to be at major level. Adiantum capillus veneris leaves contain 224.76 mg FA/gm dw of phenolics and 49.62 mg equi Rut/gm dw of flavonoids in aqueous extract. The ethanol extract showed good antioxidant activity as compared to standard i.e. ascorbic acid, it exhibits low IC50 value 0.3986 mg/gm for DPPH assay and 0.695 mg/gm for ABTS assay. Results obtained indicated that Adiantum capillus veneris leaves are endowed with free radical scavenging molecules and it can be used as a potential source of natural antioxidants and nutrients.
