Problems solved by technology

In the traditional Polygonatum extract, water leaching method is often used, but only water leaching method is used, so that the yield of Polygonatum extract is low, and there are still more active ingredients in the residue, resulting in waste

Abstract

The invention discloses an extraction process of a rhizoma polygonati extract, relating to the technical field of rhizoma polygonati extraction. The extraction process comprises the following steps: (1) pretreatment of rhizoma polygonati; (2) extraction of rhizoma polygonati saponin; (3) purification of the rhizoma polygonati saponin; (4) extraction of rhizoma polygonati polysaccharide; (5) decoloration of a rhizoma polygonati polysaccharide extracting solution; and (6) purification of the rhizoma polygonati polysaccharide. By the modes of alcohol extraction and water extraction, steroid saponin and polysaccharide in the rhizoma polygonati are extracted multiple times so as to extract active ingredients in the rhizoma polygonati as far as possible, and then purified and separated by self-made adsorption resin, not only is the purity of the active ingredients improved, but also the yield of the active ingredients is increased.

Description

Technical field: [0001] The invention relates to the technical field of Polygonatum extract, in particular to an extraction process of Polygonatum extract. Background technique: [0002] Polygonatum belongs to the perennial herbaceous plant of Liliaceae, and belongs to Chinese herbal medicine with the same origin of medicine and food. Polygonatum, sweet in taste, flat in nature, rich in starch, vitamins, minerals and various active substances. Polygonatum, as a traditional precious Chinese medicine, has the effects of invigorating qi and nourishing yin, invigorating the spleen, moistening the lungs and benefiting the kidney. It is often used for spleen and stomach qi deficiency, body fatigue and fatigue, insufficient stomach yin, dry mouth and lack of food, dry cough due to lung deficiency, labor cough and hemoptysis, insufficient essence and blood, sore waist and knees, premature graying of beard and hair, internal heat and quenching thirst. [0003] The main active ingre...
