ABSTRACT
Phytochemical constituents and molluscicidal effectiveness of Allium sativum against Bulinus globosus in Sokoto was investigated. The plants were purchased from Ramin Kura Market, Sokoto, identified and authenticated by botanist, fresh cloves of the plants were air dried, grinded in to powdered form and extracts were obtained by using maceration method with methanol; column purifications of the extract was conducted using silica gel as a stationary phase and 1:1 of N-hexane and ethyl acetate as mobile phase, thirteen fractions each containing ten mil (10ml) of the eluent were collected. Data obtained were analyzed by descriptive statistics, ANOVA and probate analysis. Qualitative phytochemicals analysis showed excess Saponins, flavonoids, Tannins, Glycosides and Antraqunones, while, Alkaloids, Volatile oils, Saponin-glycosides and steroids were moderately presents and Balsams were quietly presents. Mortalities of B. globosu snails were significanly high in fraction seven of the experimental set up, the LC50 was 15.599mg/l. Finally, based on finding from this research Allium sativum was very effective and sufficient for control of Bulinus globosus for villagers and drugs industries.
