Comparative Study on Anti-Diabetic Activity of Momordica charantia and Psidium guajava

Diabetes is a metabolic disease characterised by decreased insulin signalling and persistent hyperglycaemia. The most frequent progression of diabetes is known as diabetes mellitus which is defined as persistent hyperglycaemia brought on by either peripheral insulin resistance or impaired pancreatic β cell production of insulin. This condition is caused by the disruptions in the digestion of carbohydrates, fats and proteins which are caused by defects in the production, release and regulation of insulin. The breakdown of carbohydrates is significantly aided by the intestinal digestive enzymes α-glucosidase and α-amylase. One type of antidiabetic treatment is to lower the blood glucose levels after a meal by blocking the enzymes α-glucosidase and α-amylase. This could be a key tactic in blood glucose control. When compared to other commercial pharmaceuticals used to treat diabetes, herbal treatments are thought to be more in harmony with the human body and to have less harmful side effects. This herbal remedy is reasonably priced as well. The aim of the current study is to compare the anti- diabetic activity of the methanolic extracts of Momordica charantia and Psidium guajava. The methods used in the determination of invitro antidiabetic activity are alpha amylase and alpha glucosidase inhibitory assays. In the current study, when compared the individual inhibition activity of Momordica charantia and Psidium guajava on the intestinal enzymes (alpha amylase and alpha glucosidase), Momordica charantia has the highest inhibition that is 79.83% at 0.8 mL concentration while the Psidium guajava has shown only 70.58% inhibition at 0.8 mL concentration. Which suggests that the presence of bio active compounds may be responsible for the plants many medicinal uses, including the treatment of diabetes.
