The moringa oleifera leaf extractive and preparation method thereof with hypoglycemic activity that the invention discloses a kind of.The preparation method using pulverize and sieve, alkaline process processing, protease hydrolyzed, cellulase degradation, high-pressure homogeneous, high temperature extraction, low-temperature and high-speed centrifugation, ultra-filtration and separation concentration, protease hydrolyzed, low-temperature and high-speed centrifuge, second ultrafiltration detach concentrate, be freeze-dried etc. techniques, obtain a kind of moringa oleifera leaf extractive with hypoglycemic activity.The extract polyoses content>30%, there is good hypoglycemic activity by the verification of diabetes B rat animal experimental model, the fasting blood-glucose of diabetes B rat can be effectively reduced and enhance its oral glucose tolerance amount, function and effect are close with isodose melbine.Extraction process of the present invention is simple, entire technological process up to food-grade requirement, can be applied in the fields such as drug, health products and food. |
