Sublethal in vivo 24 h exposure to (40% and 80% of 24 h LC 50 ) active fractions of Punica granatum bark or Canna indica root or in combination with other plant‐derived molluscicides signicantly inhibited the activity of acetylcholinesterase, acid/alkaline phosphatase, Na + K + ATPase and lactic dehydrogenase in the nervous tissue of Lymnaea acuminata . The inhibition kinetics of these enzymes indicates that active fractions of both the plants caused a competitive inhibition of AChE, LDH, ALP, ACP and Na + K + ATPase.
