Screening of sudanese plants for molluscicidal activity and identification of leaves of Tacca leontopetaloides (L.) O Ktze (Taccaceae) as a potential new exploitable resource

Sixty samples of materials implicated in traditional Sudanese medicine, representing 42 plant species, 31 genera and 22 families, were tested for molluscicidal activity. Tacca leontopetaloides (Taccaceae) was identified as a potent material which could be developed as a natural snail control agent. Several active fractions containing steroidal saponins were isolated.
