Uvariodendron anisatum root extracts are used by some Kenyan herbalists. However, the claims of the plant to remove retained placenta during birth have remained uninvestigated. Therefore, the current study evaluated its uterotonic activities. Acute toxicity in Wistar rats and the phytochemical composition of the plant were also studied. The plant was collected from Embu County in Kenya. The water and ethanol extracts were prepared by maceration. Uterine strips were isolated from primed mature female Wistar rats and used to study the uterotonic activities of the extracts. De Jalon\u2019s solution and oxytocin were used as negative and positive controls, respectively. Acute oral toxicity studies were done following the OECD 423 guideline and phytochemical screening were based on standard phytochemical procedures. The study met all the approval requirements before commencement. Data obtained from the uterotonic activity were analysed by using GraphPad Prism Version 8.0.1 software and expressed as a percentage increase or decrease of mean as mean\u2009\u00b1\u2009SEM relative to the controls. The findings of acute oral toxicity were expressed using LD50. Additionally, the phytochemical components of the U. anisatum were tabulated. The uterotonic effect of Uvariodendron anisatum root water extract was higher than that of ethanol extract. A single dose of the Uvariodendron anisatum root water extract at 2000\u2009mg\/kg did not cause mortality in the tested Wistar rats. Besides, there were no changes in hematological and biochemical parameters. The extracts did not reveal changes in the gross morphology of the liver, kidney, heart, and lung of the tested Wistar rats. However, the histopathological studies of Uvariodendron anisatum root water extracts exhibited toxicity in the liver, kidney, and lung tissues of Wistar rats at a concentration of 2000\u2009mg\/kg. Alkaloids, glycosides, saponins, phytosterols, terpenes, proteins, phenols, and oils were recorded in Uvariodendron anisatum. The findings from this study provided scientific evidence which is useful in validating the use of Uvariodendron anisatum extracts in the stimulation of the uterus during birth.<\/jats:p>","DOI":"10.1155\/2022\/7393537","type":"journal-article","created":{"date-parts":[[2022,8,25]],"date-time":"2022-08-25T20:05:10Z","timestamp":1661457910000},"page":"1-12","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation of Uterotonic Activity, Acute Oral Toxicity, and Phytochemical Composition of Uvariodendron anisatum Verdc.
