PRODUCTION METHOD FOR ASTRAGALUS MEMBRANACEUS EXTRACT EMPLOYING ENZYMOLYSIS, AND A COMPOSITION FOR PREVENTING OR ALLEVIATING DIABETES OR OBESITY CONTAINING AN ACTIVE INGREDIENT COMPRISING AN ASTRAGALUS MEMBRANACEUS EXTRACT PRODUCED BY MEANS OF THE PRODUCTION METHOD

摘要

The present invention relates to a production method for Astragalus membranaceus extract employing enzymolysis, and to a composition for the prevention or alleviation of diabetes or obesity containing an active ingredient comprising an Astragalus membranaceus extract produced by means of the method. More specifically the present invention relates to an Astragalus membranaceus extraction method employing enzymolysis, characterised in that the rate of extraction and recovery of insoluble substances is increased by subjecting Astragalus membranaceus to hydrolysis using an amylase and/or cellulase, and to a composition for preventing or alleviating diabetes or obesity containing an active ingredient comprising an Astragalus membranaceus extract produced using the method. The Astragalus membranaceus extract produced using enzymolysis is advantageous in reducing blood sugar and in reducing cholesterol and triglycerides. It also exhibits advantageous effects in preventing or alleviating diabetes (including type 2 diabetes), fatty liver, hyperlipidaemia, arteriosclerosis and obesity.
