Objective: Diabetes mellitus is a highly prevalent chronic disease in Egypt leading to high socioeconomic problems, especially in the cities due to the unhealthy life style. Although many drugs are available, they have many side effects. Furthermore, the body arouses resistance after a while for the drug so it should be changed every once in a while. Plants could be a good source for drugs. In Egypt, we have a rich flora which has not been subjected to systematic screening for antidiabetic activity.
Methods: The aim of this work was to screen 264 plant extracts for their in vitro α-glucosidase inhibitory activity. Those extracts which gave more than 70% inhibition were screened on different concentrations and their inhibitory concentrations giving 50% activity (IC50) were calculated.
Results: Out of all the tested extracts, 63 gave more than or equal 70% inhibition on α-glucosidase at the tested concentration (25 ppm). After the calculation of the IC50 values, 10 extracts were chosen for further study having 5 ppm and less IC50.
Conclusion: The most active plant extract is Pinus roxburghii Sarg. branches (IC50 is 2.47 ppm).
