Effect of Avarai Kudineer on α- Amylase and α- Glucosidase Inhibition: A Preclinical Antidiabetic Study

Abstract

In recent years there has been a mounting interest towards the traditional medicine globally for the treatment of type 2 diabetes. Avarai Kudineer (AK) is a Siddha classical polyherbal formulation that has been indicated for the management of Diabetes mellitus in Siddha literature. The goal of the present study is to provide an in-vitro evidence for the  antidiabetic potential of Avarai Kudineer in terms of  inhibiting the carbohydrate digesting enzymes alpha amylase and alpha glucosidase. Aavirai Kudineer (1/4) was prepared by boiling the ingredients weighed 20g in 80ml and reduced to 20ml and filtered according to the decoction preparation method as indicted in the Siddha literature. The filtrate was dissolved in DMSO to make stock solution and serially diluted to make different concentrations ranging from 10,20,40,80 and 100 µg/ml. The triplicates (n=3) were maintained. The invitro alpha amylase and alpha glucosidase enzyme inhibition of AK sample was compared with standard drug acarbose and the IC 50 value was calculated.The data was statistically analysed and expressed as Mean ± SD (n=3). The results showed that AK had maximum activity towards the inhibition of the enzyme alpha amylase (59.83± 7.10) and alpha glucosidase (71.94 ± 1.22) when compared with the standard acarbose81.42± 5.51 and 91.59 ±12.79respectively. The results reveal that the test drug AK has appreciable alpha amylase and alpha glucosidase inhibitory activity.
