Objective: This work aims to find a new treatment based on the development of safe natural anti-diabetic mixtures. It assesses the hypoglycemic activity of natural mixtures and determines whether there are any negative side effects from the interaction of the herbs and the herbs. Methods: Six natural mixtures were tested for anti-diabetic activity, which was confirmed by a pathological histological examination. We performed a GC-MS analysis on active mixtures 1 and 2, yielding 54 and 38 compounds, respectively. The major compounds were Gingerol, Butan-2-one and 4-(3-hydroxy-2-methoxyphenyl) (97 and 64.02 per cent). Results: Among the six samples, the organic extract of mixture 1 and 2 showed a significant reduction in BGL compared to the standard drug glimepiride at a dose of 10 mg/kg ip and demonstrated a beneficial effect on renal function in alloxan-induced diabetic mice. These results were confirmed by a histopathological study which revealed that both mixture 1 and mixture 2 had decreased morphological and ultrastructural changes in the triggered liver. Docking of cuminaldehyde, Gingerol and α-Copaenin at the active site of human pancreatic enzymes α-amylase and aldol reductase revealed that these compounds had binding affinity at the active site of the enzymes. Conclusion: Our results revealed the anti-diabetic activity of non-polar mixtures consisting of long chain hydrocarbons, oils and non-polar components, thus suggesting that the herbal formulation is safe and effective for the treatment and complication of type 2 diabetes.

Pomegranate (Punica granatum Linn.) has several medicinal properties. Pomegranate juice has been reported to be an effective source of high amounts of phyto-constituents with many health and nutritional benefits. This work assessed the possible effect on blood pressure (B.P) and heart rate of P. granatum peel ethyl acetate extract (PGE) at a dosage of 400 mg / kg / day on hypertension-induced fludrocortisone Wistar rats. PGE therapy substantially lowered the B.P of hypertensive rats treated with salt fludrocortisones, but the mean blood pressure and heart rate in normotensive rats were not altered. In isolated aortic strip, the contractile reactions to noradrenalin of PGE-treated hypertensive rats have been substantially reduced. The active fraction was purified by successive chromatographic techniques resulted in isolation of quercetin and ursolic acid, this bioactive mixture induced a significant decrease in the blood pressure of hypertensive rats as compared to hypertensive control rats at a concentration of 10 mg/kg.
