Anthelmintic Activity of Nine Varieties of Cajanus cajan (L.) Millsp on Haemonchus contortus from Sheep

Background: Internal parasitosis is the most important parasitism in small ruminants tropical region. Synthetic anthelmintics are usually used for their control. Due to emergence of resistance worm population, use alternative methods such as plants bioactive molecules developed. This study aimed at assessing anthelmintic activity nine varieties Cajanus cajan, a taniferous plant cultivated West Africa. Methods: Leaves cajan were dried, ground and hydroacetonic extracts obtained by cold maceration concentration 60 mg/ml. Live adult Haemonchus contortus from sheep’s stomach exposed, triplicate, following solutions: (60 mg/ml), mg/ml) associated with polyvinylpyrrolidone (PVP) (50 Levamisole (20 phosphate buffered saline (PBS) solution. Worm death time was recorded each treatment. Result: Worms exposed shortest about 9.73±1.77 min. The potent induced 64.83±4.73 min while least efficient 156.50±23.20 PBS solution still alive after 24 hours exposure. These results indicated that four C. this have promising wormicidal. Besides that, effect tannins not only compound responsible activity.
