Leea asiatica , a folk medicinal plant of India, is used in the treatment of worm infection and other oxidative stress-related disorders, traditionally. In the present study, the in vitro anthelmintic and in vitro antioxidant activity of different fractions of the methanol extract from the Leea asiatica leaves were evaluated. The fraction displayed significant anthelmintic activity against Indian adult earthworms (Pheretima posthuma). The ethyl acetate fraction showed a better paralysis activity (13.99 ± 0.59), while the methanol fraction showed a better death time (63.76 ± 0.73 minutes), when compared with other fractions, at a dose of 50 mg/ml concentration. The anthelmintic activity of methanol and the ethyl acetate fraction were almost similar and comparable to the standard drug, piperazine citrate. The petroleum ether fraction did not produce a potent anthelmintic effect compared to the standard. The in vitro antioxidant activity was evaluated by using the diphenyl-picrylhydrazyl (DPPH) radical scavenging assay, nitric oxide radical scavenging assay, lipid peroxidation assay, and the ferric thiocyanate method. The ethyl acetate fraction showed better antioxidant activity in all tested methods. The IC 50 value of the ethyl acetate fraction in the DPPH radical, nitric oxide radical scavenging assay, and lipid peroxidation assay were 9.5, 13.0, and 57.0 mg/ml, respectively. The fractions significantly (P < 0.05) inhibited the peroxidation of linoleic acid. The results confirmed the folk use of Leea asiatica in warm infection and the plant could be viewed as a potential source of natural anthelmintic and antioxidant compound.
