Abstract

Eradication of malaria will depend on discovery of new intervention tools such as anti-malarial drugs. Due to the increasing interest in the application of propolis against significant clinical pathogenic agents, the aim of the present investigation was to evaluate the anti-plasmodial effect of Iranian propolis extracts against chloroquine (CQ)-sensitive Plasmodium falciparum 3D7 and Plasmodium berghei (ANKA strain). Crude samples of honeybee (Apis mellifera) propolis were collected from four provinces in northern (Kalaleh, Golestan), northeastern (Chenaran, Razavi Khorasan), central (Taleghan, Alborz) and western (Morad Beyg, Hamedan) areas of Iran with different types of flora. The dried propolis samples were extracted with three different solvents, including ethanol 70% (EtOH), ethyl acetate (EA) and dichloromethane (DCM). All extracts were shown to have in vitro anti-plasmodial activity with IC50 ranging from 16.263 to 80.012 µg/mL using parasite lactate dehydrogenase (pLDH) assay. The DCM extract of Morad Beyg propolis indicated the highest anti-plasmodial activity (IC50: 16.263 ± 2.910 μg/mL; P = 0.027, Kruskal-Wallis H-test). The samples were also evaluated in mice for their in vivo anti-plasmodial effect. The curative e...Continue Reading
