anthelmintic

The anthelmintic activity of the ethanolic and aqueous extracts of Foumban propolis and PROMAX-C was evaluated in vitro, on the nematode parasite of cattle Onchocerca ochengi. The objective of this study was to find an alternative of synthetic anthelmintic to fight human and animal onchocerciasis. Increasing concentrations of ethanolic and aqueous extracts of propolis and PROMAX-C were prepared in RPMI 1640 culture medium for O. ochengi incubation. Dimethylsulfoxide of 0.5 % concentration was the negative control and the positive control was ivermectin. The anthelmintic activity was assessed every 24 and 48 hours and expressed as mortality rate. Acute oral toxicity was assessed in Mus musculus for 14 days and subacute toxicity was assessed in males and females of Ratus norvegicus for 28 days. Quantification of polyphenols, tannins and flavonoids was performed with a spectrophotometer using gallic acid and rutin as standards. The LC50 value was 52.50 ± 0.04 µg/mL for PROMAX-C, while those of the ethanolic and aqueous extracts were 75.50 ± 0.92 and 261.44 ± 18.98 µg/mL, respectively after 48 hours. The test with ivermectin showed a high efficacy on O. ochengi nematodes with a LC50 value of 100.05 ± 0.35 µg/mL. The ethanolic extract of propolis did not show signs of toxicity on mice. During subacute toxicity, the relative organ weights (kidney, liver, lung, spleen and heart) taken from the rats at the end of treatment did not change significantly. Biochemical showed a decrease in AST and ALT in both sexes at all doses. Thus, the consumption of propolis and PROMAX-C is recommended to fight against onchocerciasis.

Herein, a series of azetidinone derivatives incorporating dihydropyrimidinone moiety 4(a-h) were prepared. The structures of newly synthesized compounds were confirmed on the basis of elemental analysis, FTIR and 1H NMR spectroscopy. The synthesized compounds were evaluated for their anthelmintic and anti-bacterial activity and it was found that the compounds were pharmacological active and gave appreciable results.

The love affair of Asian’s with Ling zhi, the Chinese name for Ganoderma lucidum and related species can be traced back over two thousand years. Ganoderma lucidum has been used for a broad spectrum of health benefits from preventive measures and maintenance of health to the regulation or treatment of chronic as well as acute life threatening illness. The present study was done to compare the Aqueous and methanolic extract of Ganoderma lucidum for anthelmintic activity and to compare the methanolic and chloroform-acetone extract of Ganoderma lucidum for antibacterial activity. Aqueous extract of mushroom did not show any result for anthelmintic activity, while the methanolic extract (60 mg/ml) was equally effective as standard (Albendazole 20 mg/ml). For antibacterial activity both the methanolic (350 mg/ml) and chloroform-acetone (350 mg/ml) extracts showed effective results, but the results of choloroform-acetone extract were more effective than methanolic extract and standard (Gentamycin 40 mg/ml). Key words: anthelmintic, antibacterial, methanolic extract, aqueous extract.

The anthelmintic activity of fruit extracts of an Indian Medicinal plant Syzygium cuminii Linn. was evaluated on earthworms of Pheretima posthuma. This is because earthworms have anatomical and physiological resemblance with that of intestinal roundworm parasites of human beings. Here anthelmintic activity of the herb was determined by time taken for paralysis and death of earthworms after suitable treatment and comparison with standard drug piperazine citrate. The ethanol extract of Syzygium cuminii fruit at concentration of 50 mg/ml showed most pronounced activity. The results suggest that fruits of Syzygium cuminii possess anthelmintic activity. There is scope for future study on this plant.
