Abstract

Background and objectives: Ficus mucuso is a plant from the Moraceae family used in traditional medicine in different regions of Cameroon to treat diabetes, epilepsy, and psychosis. This study aims to evaluate the effects of the decoction of Ficus mucuso bark fragments on mouse models of schizoaffective disorder induced by lipopolysaccharide.

Materials and methods: The plant material used was Ficus mucuso bark, which was harvested in Manwi (Ngaoundéré). Forty-two mice with a body weight of 18–30 g were used. Schizoaffective disorder was induced by the intraperitoneal administration of lipopolysaccharide (0.83 mg/kg) for 21 days, after which the mice were treated with decoction at doses of 21.8, 43.5, 87, or 174 mg/kg, or haloperidol (2.5 mg/kg). The anxiolytic and memory effects, antioxidant potency, and phytochemical profile were evaluated.

Results: The evaluation of the pharmacological properties showed that Ficus mucuso reduced anxiety by significantly increasing the percentage of entries and the time spent in the open arms at the 21.8 and 43.5 mg/kg doses. At these doses, it also improved memory and learning capacity. The antioxidant power of Ficus mucuso was demonstrated by a significant decrease in MDA and a significant increase in GSH and CAT at doses of 21.8 and 43.5 mg/kg, as well as at 87 mg/kg. These results are comparable to those of haloperidol (2.5 mg/kg). The phytochemical profile reveals the presence of alkaloids, flavonoids, polyphenols, and saponins.

Conclusion: The different results demonstrate that Ficus mucosa and haloperidol have comparable effects, which justifies their use in traditional medicine.
