Abstract

This study evaluated the proximate and phytochemical constituents of ethanolic seeds extracts of Cola nitida and Cola acuminata. The seeds of C. acuminata and C. nitida were purchased and air-dried at room temperature. The dried seeds were pulverized to ground sample. The sample was weighed and used for the proximate and phytochemical analysis. The qualitative phytochemical screening revealed the presence of secondary metabolites: alkaloid, flavonoids, tannins, phenols, Cardiac glycoside, terpenes (tri), steroids and saponins, but the absence of anthraquinones. The seed of C. nitida was higher in alkaloids, saponins, phenols, tannins, steroids, triterpenes and C-glycosides than the seed of C. acuminata, while the seed of C. acuminata was higher in flavonoids and carbohydrates than the seed of C. nitida. There was no statistical significant difference (p>0.05) between the levels of alkaloids, saponins, phenols and tannins in seed of C. nitida and seed of C. acuminata. The difference between the levels of flavonoids, carbohydrates, steroids, triterpenes and C-glycosides in seed of C. nitida and seed of C. acuminata was statistically significant (p<0.05). The seed of C. nitida was higher in moisture, ash, lipid and crude protein than the seed of C. acuminata, while the seed of C. acuminata was higher in crude fibre and carbohydrate than the seed of C. nitida. There was no statistically significant difference (p>0.05) between the levels of moisture, ash, lipid, crude fibre and crude protein in seed of C. nitida and seed of C. acuminata. The difference between the level of carbohydrate in seed of C. nitida and seed of C. acuminata was statistically significant (p<0.05). The result shows that seeds of C. acuminata and C. nitida possess an appreciable level of phytochemicals. It could be a good raw material for the production of some medicinal drugs and can be used in folk medicine for the treatment of some diseases.

Abstract

Diabetes mellitus (DM) is a metabolic disorder that remains a major health concern worldwide. It is associated with derangement of carbohydrate, protein, and lipid metabolism. This study evaluates the antidiabetic and hepatoprotective effects of aqueous and ethanolic leaf extracts of Mitracarpus hirtus on alloxan-induced diabetic rats. Fifty-five male Wistar rats were divided into 11 groups, with diabetes induced by alloxan. Treatment with aqueous and ethanolic extracts, along with Glibenclamide, lasted three weeks. At the end of the treatment period, the rats were sacrificed and blood samples were collected via cardiac puncture for biochemical analysis. Findings revealed a significant decrease (p<0.05) in fasting blood sugar (FBS) in group 10 (99.8 ± 15.74 mg/dL) when compared with group 2 (274.2 ± 7.95 mg/dL) in week 1. Week 2 also revealed a significant decrease (p<0.05) in group 11 (84.6 ± 14.98 mg/dL) when compared with group 2 (262.8 ± 15.94 mg/dL). Week 3, further revealed a significant decrease (p<0.05) in group 9 (79.4 ± 25.13 mg/dL) and group 11 (83.6 ± 8.35 mg/dL) when compared with group 2 (289.6 ± 20.89 mg/dL). Aspartate Aminotransferase (AST) revealed a significant decrease (p<0.05) when group 11 (54.38 ± 15.74 U/L) was compared with group 2 (146.66 ± 11.35 U/L). Similarly, Alanine Aminotransferase (ALT) significantly decreased (p<0.05) when group 11 (53.46 ± 4.6 U/L) was compared with group 2 (101.42 ± 16.01 U/L), while total protein and albumin increased in all treated groups. Group 5 (0.64 ± 0.11 mg/dL) in Total bilirubin (TB) had the lowest mean when compared with group 2 (2.69 ± 0.52 mg/dL). All treatment groups significantly decreased (p<0.05) Triglyceride (TG) and Cholesterol (CHOL). From this study, it has been shown that the aqueous and ethanolic leaves extracts of Mitracarpus hirtus may have the potential to ameliorate the complications due to diabetes in a dose dependent manner.
