Abstract
Background and objectives: Piper guineense (African black pepper) is a widely consumed spice in some parts of Central and Western Africa, especially Nigeria, due to its nutritional and medicinal properties. This study investigated biochemical effects of extract of P. guineense seeds on lipid profile, renal function parameters, and antioxidant status of Cavia porcellus.
Methods: Forty guinea pigs (weighing 200–300g) were equally divided into a control group and three experimental groups. Animals in the control group received 1 mL of distilled water daily for 28 days, while animals in the experimental groups 1, 2, and 3 received 0.5 mL of distilled water along with 10, 20, and 20 mg/100 g body weight powered seeds daily for 28 days.
Results: Phytochemical studies revealed the presence of flavonoids, alkaloids, tannins, saponins, and calcium. The median lethal oral dose of the aqueous extract of P. guineense seeds was greater than 5,000 mg/kg, indicating a high degree of safety. The extract at dose of 30 mg/100 g body weight had the most beneficial effects on lipid profile, renal function parameters, and antioxidant status of guinea pigs when compared with other groups.
Conclusion: Given the beneficial effects of P. guineense on lipid profile and renal function parameters, the plant can be incorporated in daily diets to ensure receiving adequate amount of essential vitamins, phytochemicals, and other nutrients present in the plant.

Abstract
Background and objectives: Trichomonas vaginalis causes human trichomoniasis, a common type of protozoan vaginitis. Due to the increasing incidence of drug-resistant trichomoniasis, new pharmacological research is needed. The aim was investigation of the activity of Ferula pseudalliacea against T. vaginalis, and preliminary phytochemical analysis of its extracts.
Methods: Essential oil and various extracts of F. pseudalliacea roots, including n-hexane, ethyl acetate and methanol, were obtained. Susceptibility testing of the plant products was done on five T. vaginalis isolates by using microtiter plate method. Minimum lethal concentration (MLC) and growth inhibitory percent (GI%) of sub-MLC concentration were reported, after 24 and 48 hours’ exposures. Phytochemical screening of the extracts was done using standard procedure.
Results: Antitrichomonal effect of the plant products depended on time and concentration. The greatest effect was observed in 48-hour exposure. The essential oils and n-hexane extract of F. pseudalliacea demonstrated a remarkable activity with MLC of 250 µg/ml and following by the ethyl acetate (MLC=500 µg/ml) and methanol extract (MLC=1000 µg/ml), with GI% 92.8, 50.6, 85.2, and 42.8, respectively. The bioactive constituents of the extracts were coumarins, terpenoids, steroids, phenols, tannins and glycosides.
Conclusion: The results of this study demonstrated in vitro antitrichomonal properties of F. pseudalliacea. Therefore, further studies are needed to investigate the potential of the antitrichomonal activity of its bioactive constituents.
