Tinea capitis is a very common fungal infection in children. It is characterized by the appearance of white circular spots on the patient’s head. Piliostigma reticulatum (D.C.) Hochst, Terminalia avicennioids (Guill and Perr), Diospyros mespiliformis Hochst and Securidaca longipedunculata Fres are plants used therapeutically in the treatment of this disease in external application, in the form of a poultice. Chemical screening of aqueous and methanolic extracts of these plants reveals the presence of phenolic and terpenoid compounds but not alkaloids. The antifungal activity of the extracts of these plants, evaluated by the agar medium diffusion method using the fungal strain Candida albicans, showed that the crude extracts of S. longepedunculata and D. mespiliform have low antifungal activity compared to Nystatin. P reticulatum and T avicennioides extracts have average antibiotic activity. The evaluation of the antifungal activity of the fractions of the methanolic extract, obtained by treatment with different solvents including hexane, dichloromethane and ethyl acetate, shows that the acetate fraction is more active than that obtained with the dichloromethane. The fractions obtained with hexane are inactive.
