The effect of Marigold flower extracts on growth of Leishmania.

Abstract

This study searched in the inhibiting potency of different concentrations (12.5, 25, 50 and 100 µg/mL) of both aqueous and methanol extracts of marigold plant flower Calendula officinalis against the promastigote of Leismania major, L. donovani and L. mexicana. Both flower extracts approved inhibiting potency against the growth of promastigotes of Leishmania major with rates 51% and 62%, respectively but showed only a slight effect on L. donovani and L. mexicana. It is concluded that the aqueous and methanolic marigold extracts have selective inhibiting potency of Leishmania major.
