In-vitro scolicidal activity of Mallotus philippinensis (Lam.) Muell Arg. fruit glandular hair extract against hydatid cyst Echinococcus granulosus

ABSTRACT

OBJECTIVE@#To investigate new scolicidal agent from natural resources to cope with the side effects associated with synthetic drugs in Echinococcosis.@*METHODS@#The scolicidal potential of methanolic fruit powder extract (10 and 20 mg/mL) of Mallotus philippinensis (M. philippinensis) was investigated. Viability of protoscoleces was confirmed by trypan blue exclusion method, where mortality was observed at concentration of 10 and 20 mg/mL in 60 min treatment against Echinococcus granulosus (E. granulosus), under in-vitro conditions with reference to the known standard drug Praziquantel®.@*RESULTS@#At concentration 10 and 20 mg/mL, the mortality rate was observed 97% and 99% respectively for 60 min treatment; while up to 93% mortality was observed with 20 mg/mL for only 10 min treatment. The concentration above 20 mg/mL for above 2 h showed 100% mortality, irrespective of further incubation.@*CONCLUSIONS@#As compared with the standard anti-parasitic drug Praziquantel our extract has significant scolicidal activity with almost no associated side effects.
