ABSTRACT
A homogenate of raw garlic was chemically fractionated and the toxicity of individual fractions against the snails Lymnaea acuminata and Indoplanorbis exustus was compared. Allicin (allyl 2-propenethiosulphinate) was tentatively identified as the active moiety causing snail death by co-migration of the active agent with extracted and synthetic allicin on TLC plates.
