Some traditional medicinal plants are known to have efficacy as a medicine for diabetes. Active compounds
produced by a plant can be derived from endophytic microbes that live in these plants. One way diabetes drugs work
is to prevent digestion of complex carbohydrates into glucose so that glucose intake is reduced. Alpha-glucosidase
inhibitor is a compound that can prevent the digestion of carbohydrates, especially starch into glucose. This study
aimed to test the inhibitory activity of alpha gluosidase PR-3 isolate, an endophytic bacteria from Momordica
charantia. The results showed that the crude extract (supernatant) from PR-3 has the capability of the enzyme alpha
glucosidase inhibition that is equal to 61.2% compared with positive control compound acarbose 1 mg / ml. The
results also showed that the use of maltose as carbon source produce the highest an alpha glucosidase inhibitor
(54,97%), followed by the starch (47.77%), glucose (31.97%), fructose (44.14%) and sucrose (27.7%).
