Abstract

This study investigates the hypoglycaemic effects of the ethanol stembark extract of Vitellaria paradoxa on hyperglycemic rats. It also investigates the phytochemical content of ethanol stem bark extract of Vitellaria paradoxa using the method of Soforh. The result shows that the ethano| stem/bark of the plant contains Tannins 3.92/mg/100g, Alkaloid 7.12/mg/100g, Flavonoids 1.03/gm/100g, phenolics 12.72/mg/100g, Glycosides 4.13/gm/100g, saponins 2.15/mg/100g respectively. The hypoglycemic properties of ethanol stem bark extract of Vitellaria paradoxa were investigated using Fifteen albino Wister rats weighing between 200g to 230g were induced with alloxan monohydrate to make them diabetic. The rats were divided into five groups of three rats. The first group were not induced, tagged normal. The second groups were induced sstandard drug glibenclamide throughout the study period. The fourth groups were induced and treated with 250/mg/kg body weight of the ethanol stem/bar extract of Vitellaria paradoxa throughout the study period. The fifth groups were induced and treated with 500/mg/kg body weight of the extract. The fasting blood glucose level of the rats were taken every three days’ interval for 21 days. At the end of 21 days, the rats treated with 250/mg/kg body weight which started with elevated blood glucose level after induction of 207/mg/dl reduces to 124/mg/dl, similarly the treated with 500/mg/kg body weight of the extract with initial elevated blood glucose level after the induction with diabetic of 221/mg/dl got reduced to 145/me/dl. This indicates that ethanol bark tract of Vitellaria paradoxa showed hypoglycemic properties.

Abstract

The aim of this research is to analyse the flavonoid, amino acid, and vitamin profiles of ethanol seed extract of Annona squamosa using high performance liquid chromatography (HPLC). The fruits of Annona squamosa were collected from Takum, Taraba State, the seeds were removed from the fruit washed with water, dried in the shade and then pulverized into fine powder. For the crude extraction, the method adopted by Yakubu et al. (2020) was adopted for this protocol. The IC50 of the seed was found to be 3.87. The total flavonoid content was significantly higher (182.76±0.61) compared with the total phenolic compound (70.34±3.04). A reliable detection and peak resolution were obtained from the HPLC analysis. The result showed the presence of nine amino acids, which include; Threonine (9.6%), Phenyl Alanine (17.0%), Aspartic Acid (26.0 %), Glutamic acid (16.0%), Leucine (5.7%), Iso-Leucine (5.3%), Glycine (5.0 %), Arginine (2.3), Glutamine (13.2%), three vitamins; vitamin K (0.4%), vitamin B1(63.0 %) and B3 (36.6%), and three flavonoid compounds Trolox (0.2%), Quercetin (2.1%) and Coumaric acid (97.7%) in plant sample. The phytochemical study confirms that the seed of Annona squamosa rich sources of amino acids such as and these herbal raw materials can exhibit a wide range of pharmacological activities.
