The present study was aimed to assess the in vitro ovicidal, larvicidal and adulticidal activity of methanolic extract and its fractions from fruits of Piper longum against strongyle ova, larvae and adult amphistomes respectively. The fruits of P. longum was identified and the accession number 006 was obtained. The phytochemical analysis revealed the presence of tannins, flavonoids, glycosides, phenolics, diterpenes and triterpenes in extract and fractions of P. longum. The extract and fractions were diluted serially in 6.25 per cent tween 80 to obtain concentrations of 500, 250, 125, 62.5, 31.25, 15.63, 7.81, 3.91 and 1.95 mg/mL. Ivermectin and thiabendazole at 10 \μg/mL acted as positive controls and 6.25 per cent tween 80 as negative control. The methanolic extract was highly active against ova with IC50 of 0.026 mg/mL. The n-hexane fraction was potent in inducing larval mortality with IC50 of 1.383 mg/mL while chloroform fraction inhibited larval migration with IC50 of 1.796 mg/mL. Amphistomes were highly sensitive for methanolic extract of P. longum which possessed IC50 of 5.493 mg/mL Based on IC50 values, the methanolic extract was found to be most potent while chloroform fraction was effective against ova, larvae and also adults. GCMS analysis of potent methanolic extract revealed the presence of piperidinone, hydrocinnamic acid, ethylhexahydro azepine, methyleugenol, hexadecanoic acid and caryophyllene oxide which may have contributed for the anthelmintic activity. The acute oral toxicity study revealed mild vascular changes in liver. From the present study, it can be concluded that chloroform fraction of P. longum possessed maximum broad spectrum anthelmintic activity comparable to controls.

Introduction: The anthelmintic activity of various extracts of leaves of Ocimum sanctum and Mallotus phillipensis was assessed in vitro against Setaria digitata. Materials and Methods: The leaves of Ocimum sanctum and Mallotus phillipensis were collected and were extracted using methanol, dried and stored under refrigeration till further use. The aqueous extract was taken as a decoction. The methanolic extract was further fractionated by taking solvents of increasing polarity viz, hexane, chloroform, n-butanol and water. The extract as well as the fractions were analysed qualitatively for various phytochemical constituents. Fresh nematodes (Setaria digitata) were recovered manually from the peritoneum of infested buffalo, were washed and transferred to the extract containing petriplates (concentrations of 50, 25, 12.5, 6.25, 3.125 and 1.56 mg/ml) immediately and the motility/death of Setaria digitata was noted. Results: The presence of flavonoids and tannins were detected in all the extracts where was phenolics as absent in the hexane fraction. The methanolic extract of Tulsi and Kamla produced death of nematodes in concentrations of 3.125 mg/ml and the extract of tulsi was found to be more potent. Similar results were also observed in the case of hydro alcoholic extract whereas the aqueous extract showed no effect. The chloroform fraction of Ocimum sanctum and n-butanol and chloroform fractions of Mallotus were equally potent in inhibiting the motility and producing death of the worms. The control drug, albendazole produced death in 30 minutes in both the concentrations. Conclusion: It could be concluded that higher doses of the extract are as potent as albendazole.
