The Anti-Hyperglycemic Effects Of Phaleriamacrocarpa Leaves Extract On Streptozotocin–Induced Diabetic Rats
The antidiabetogenic effect of Phaleriamacrocarpa leaves methanol extract on STZ-induced diabetic rats has
been investigated. Diabetic rats were orally force-fed daily with the extract (500 mg/kg bw) for 14 days. The reductions in
blood glucose levels determined by evaluating levels of RBG, FBG, IPGTT, as well as, total body weight, along with the
period of extract treatment. Reduction in blood glucose levels have indicated significantly in treated rats (9.83±4.98 mmol/L)
compared to non-treated (21.05±1.78 mmol/L). Diabetic animals treated with the extract showed highly significant increased
pattern of weight gain (253.73±5.54 g), this pattern also observed in non-diabetic group treated with the extract (253.80±5.30
g), compared to diabetic non-treated (239.30±6.11 g) and non-diabetic control (235.94±6.32 g). The extract did not cause
any acute toxicity or allergic reactions. Qualitative phytochemical analysis of the extract showed the presence of alkaloid,
saponin, flavonoid, tannins, reducing sugar, terpenoids, cardiac glycosides, and phenolic, which can account for the observed
antihyperglycemic activity. Results indicated that this extract can be used with safety to improve glucose tolerance in
glucose-impaired cases, and suggest that this extract may serve as a candidate for developing safe, complaisance, and
promising nutraceutical product for the management of diabetes.
