 en Anthelminthic Efficacy Of Aqueous Extract Of Acanthus montanus Leaf Against Strongylid Nematodes Of Small Ruminants.
Adamu, M.; Oshadua, O.D. & Ogbajea, C.I.


The anthelminthic efficacy of the crude aqueous extract of Acanthus montanus (Nees) T. Anders (Acanthaceae) against strongylid nematodes of small ruminants was investigated using the in-vitro egg hatch and larval growth inhibition assays. Faecal samples collected per rectum from sheep and goats were subjected to parasitological examination using the McMaster counting technique with a yield of 700 eggs per gram (E.P.G.) of faeces. Crude aqueous leaf extract of Acanthus montanus was extracted using cold water extraction with a yield of 13.01% w/w. Egg hatch assay revealed a 91.75% reduction in egg hatch at concentration of 25mg/ml of the extract. The extract had a 100% inhibition, at 200mg/ml concentration which was equivalent to the activity of 3.125mg/ml albendazole. The distilled water control however, showed a 0% inhibition. Larval growth inhibition assay results showed the extract on Day 1 at 25mg/ml and 200mg/ml concentrations yielded 67.02% and 85.26% larval inhibition. On Day 2, 100% inhibition was obtained on all concentrations of the extract except for 25mg/ml that yielded 88.30%. Albendazole however, had a 100% larval inhibition for all concentrations on Day 2. A 100% larval inhibition was recorded on Day 3 from the 25mg/ml concentrations. The mean percentage larval inhibition of the extract at 200mg/ml (92.63%) was comparable to the standard anthelminthic (albendazole) at 12.50mg/ml (92.28%). These findings showed that there is a pharmacological basis for the folkloric claim of the anthelminthic effect of Acanthus montanus.
