This study was undertaken to investigate the leaf part of the plant for analgesic and anti-inflammatory. The ethanol extract of Ficus iteophylla leaves (100, 200, and 400mgkg -1 , i.p) was evaluated for analgesic and anti-inflammatory activities. The analgesic effect was studied using acetic acid-induced abdominal constriction and hot plate test in mice, while the antiinflammatory effect was investigated using carrageenan induced paw oedema in rats. The ethanol extract at 100mgkg-1 , and 400mgkg -1 significantly (P< 0.05) inhibited acetic acid induced writhes by 1.50 ± 0.43, 3.0 ± 0.82 and 1.0 ± 0.82 respectively. It also exhibited significantly (P< 0.05) anti-inflammatory by 0.11 ± 0.02, 0.11 ± 0.03, 0.08 ± 0.01 respectively. The preliminary phytochemical screening of the plant extract revealed the presence of flavonoids, steroids, tannins and saponins while the effect of flavonoids, steroids and tannins on analgesic and inflammatory has been reported. The intraperitoneal median lethal dose (LD 50 ) value of the extract was found to be 3807.8 mgkg -1 body weights. The result obtained from this study shows that the extract of Ficus iteophylla contained phytochemical constituents with analgesic and anti-inflammatory activities, therefore the leaf part of the plant could be used in the management of pain and inflammatory conditions.
Schizophrenia is a highly disabling chronic psychiatric illness. The existing antipsychotic agents are associated with untoward effects and drug interactions leading to the intensification of search for newer agents with better efficacy and safety profile. Securinega virosa is a commonly used medicinal plant in African traditional medicine. The decoction of the leaves of the plant in combination with other plants is used in the management of mental illness. In this study, we evaluate the antipsychotic potential of the methanol leaf extract (25, 50 and 100 mg kg(-1)) of the plant using apomorphine-induced stereotypic climbing behavior and swim-induced grooming tests, all in mice. The CNS depressant effect was also evaluated using ketamine-induced sleep test mice. The extract at the highest dose tested (100 mg kg(-1)) significantly reduced the apomorphine (1 mg kg(-1))-induced stereotypic climbing behavior after 30 min. Similarly, haloperidol (2 mg kg(-1)), the standard agent significantly (p<0.001) decreased the mean climbing behavior. In the swim-induced grooming test, the extract significantly (p<0.01) and dose-dependently decreased the total grooming time. Similarly, haloperidol (2 mg kg(-1)) significantly (p<0.001) decreased the mean grooming activity. The extract significantly increased the total ketamine-induced sleep duration at doses of 50 and 100 mg kg(-1). These findings suggest that the extract possesses antipsychotic and sedative potentials and lend credence to the ethnomedical use of the leaves of the plant in the management of mental illness.
