Histopathological Studies

Aim: In this study, the methanol stem bark extract of Detarium microcarpum was evaluated for sub-chronic, biochemical and histopathological studies. Methodology: Sub-chronic toxicity studies was investigated in rats administered with 35, 70 and 140 mg/kg doses of the extract orally for 28 days using standard laboratory procedures after the acute toxicity was carried out. Results: The median lethal dose (LD50) of the extract was calculated to be equal to (≥) 5000 mg/kg body weight in rats orally. Serological studies revealed significant (p<0.05) decrease in Alanine aminotransferase (ALT) at all doses tested, while at 140 mg/kg it caused a significant (p<0.05) increase in Alkaline Phosphatase (ALP). At doses of 70 and 140 mg/kg there was a significant (p<0.05) reduction in creatinine level. Histopathological studies on the liver showed moderate hepatocellular necrosis at doses of 35 and 70 mg/kg, while at 140 mg/kg there was intense hepatocellular necrosis,  Kupffer cells and lymphocytes hyperplasia. The Kidney showed intense necrosis of tubules and glomerular necrosis with lymphocytes hyperplasia at all doses tested.  The spleen also showed intense lymphocyte hyperplasia at all doses with sinusoidal congestion at the lowest dose of 35 mg/kg. The heart showed slight necrosis of cardiac muscle cells at all doses with blood congestion at 35 and 70mg/kg body weight. Conclusion: The study indicates that prolong use of the extract in the management of disease conditions may be associated with some adverse effect of some vital organs.

Background: Malaria is a parasitic infection that is common in the tropical and sub-tropical regions of the world. It is estimated to kill one million individuals annually. Detarium microcarpum (Fabaceae family) is used traditionally for the treatment of malaria, diabetes, hypertension, convulsions, pneumonia, leprosy, and meningitis. The purpose of this research was to evaluate the antiplasmodial potential and safety profile of the methanol extract of D. microcarpum stem bark. Methods: The extract was subjected to phytochemical screening and oral median lethal dose (LD50) estimation. Using curative, suppressive, and prophylactic experimental animal models, antiplasmodial activity was assessed in mice infected with chloroquine-sensitive Plasmodium berghei berghei. Biochemical and hematological tests were conducted in rats orally administered with the extract for 28 days. One-way analysis of variance (ANOVA) was used to analyze the data, followed by Dunnett's post hoc test. Results: Alkaloids, flavonoids, saponins, tannins, triterpenes, and glycosides were found in the extract through phytochemical analysis. When compared to the negative control group, the extract at the tested doses (200, 400, and 800 mg/kg) showed a significant (P < 0.001) curative, suppressive, and prophylactic effect and significantly (P < 0.001) prolonged the survival time of mice in the treated groups. The extract had an insignificant (P > 0.05) effect on the biochemical and hematological parameters tested. Conclusions: The results suggest that the stem bark extract of D. microcarpum at the doses tested possesses antiplasmodial activity and is relatively safe after short-term use.

Despite the availability of anticancer drugs, breast cancer remains the most death-causing tumor-related disease in women. Hence, there is a need for discovery and development of efficient alternative drugs, and sources such as plants need to be explored. In this study, antioxidant capacities and inhibitory effects against MCF7 cells of the extracts of stem bark of three Nigerian medicinal plants (Detarium microcarpum, Guiera senegalensis, and Cassia siamea) were investigated. The D. microcarpum extracts had the highest antioxidant and antiproliferative effects, followed by that of G. senegalensis, and the C. siamea extracts had minimal effects. The IC50 values of the methanol and aqueous extracts from the three plants that inhibited the proliferation of MCF7 cells ranged from 78–> 500 μg/ml. Moreover, all the plant extracts but the aqueous extract of Cassia siamea exhibited antimetastatic action and induced apoptosis and cell cycle arrest in MCF7 cells. Liquid chromatography/time-of-flight/mass spectrometry profiling revealed that the five potent extracts contain many phenols and omega-6 fatty acids, and some of the identified compounds (isorhamnetin, eupatorin, alpinumisoflavone, procyanidin B3, syringin, and gallic acid) have been reported to have antiproliferative effects on cancer cells. Hence, the stem bark of these plants could be potential sources of antibreast cancer agents.

Reported Data

The antibacterial activity of the stem bark of Detarium microcarpum was investigated with the aim of isolating the most active ingredient. Extraction solvents used to prepare the crude extracts of the stem bark were, n-hexane, ethyl acetate, chloroform, methanol. Test bacteria included Escherichia coli, Salmonella enteriditis, Shigella dysenteriae, Staphylococcus aureus and Vibro cholerae. The extracts demonstrated a wide range of antibacterial activity on the microorganisms, with the ethyl acetate crude extract being the most active. Using liquid vacuum chromatography over silica gel, the extract was eluted with n- hexane, ethyl acetate and methanol and fifty- five fractions labeled Gl - G55 were obtained. Further antibacterial assays of the fractions led to the identification of fraction G34 as the most active fraction. This fraction was subjected to spectroscopic analysis using NMR, [(1H -1H NMR, 13C-NMR) and 2D-NMR (COSY and HMBC)]. The results showed good agreement with reported data on Copalic acid, a diterpene with chemical formula C O H O . This compound is 2 34 2 the most active ingredients of this plant and is likely to be responsible for its antibacterial activities.
