A METHOD FOR PREPARING A MIXTURE CONTAINING NATURAL VITAMIN P FROM HIPPOPHAE RHAMNOIDES L.

摘要

The present invention provides a method for preparing a mixture containing natural vitamin P from Hippophae rhamnoides L. The mixture containing 0.5 - 20% of vitamin P and 2 - 30% of vitamin C are prepared by taking juice, degassing, enzymolysis, degreasing, homogenizing, deacidifying, desugaring, microfiltrating, freeze-drying and pulverizing. The method is simple, a combination of low-temperature and biophysics applied in the method solves the problem of brown change of high active substances in Hippophae rhamnoides L caused by high-temperature oxidation; during the entire production process, no organic solvent is required; no residue remains; the cost is low; and the yield of bioactive substances is high; the co-existing of vitamin P and vitamin C in the prepared products can promote a better absortion in human body.
