Abstract: Provided are a method for producing a purified Salacia genus plant extract having improved flavor by increasing the α-glucosidase inhibitory activity of the extract without significantly reducing the recovery rate of the extract concomitantly with purification; and a purified Salacia genus plant extract. The method for producing a purified Salacia genus plant extract includes an extraction step of bringing a Salacia genus plant-containing raw material extract including at least one of a Salacia genus plant, a Salacia genus plant extract, and a Salacia genus plant ground product, into contact with 0.1 to 20 mass % of activated carbon in the presence of an extraction solvent.
