Abstract
A phytochemical screening and in vitroanthelminthic activity of aqueous and ethanolic extract of Senna italicaon Haemonchus contortuswere conducted. Polyphenol, tannin and flavonoid contents were determinedby using gallic acid and rutin. egg hatching inhibition test was carried out on fresh eggs; larval mortality test was conducted on infective larvae (L3) and adult worm mortality test was conducted. Eggs, larvae and adults worms were incubated in aqueous and ethanolic extract of S. italicaat different concentrations (0.1; 0.3; 0.5; 0.7 and 1 mg/mL). All extracts of plants showed an effect on all stages of H. contortuswith high efficiency variations depending on the dose used. The inhibition of eggs hatching rate increased from 8.67±1.53% to 65.67±1.15% and from 24.67±1.53% to 80±1.73% respectively for aqueous and ethanolic extract of S. italic.The larval mortality rate increased from 12.22±2.34% to 56.67±4.9% after 24 h and from 45.28±4.11% to 91.25±3.73% after 48 h for aqueous extract and from 30.07±2.84% to 70.83±6.31% after 24 h and from 48.79±3.73% to 96.25±4.79% after 48 h for ethanolic extract. After 24 h of exposure to aqueous and ethanolic extract of S. italica, the adult mortality rate varies from 55.56±9.62% to 83.33±9.62% for aqueous extract and from 61.11±9.62% to 88.89±9.62%.These in vitroresults confirm the use of S. italicain traditional medicine
