Preparation method for highly active polygonatum sibiricum cream

Abstract

The invention provides a preparation method for a highly active polygonatum sibiricum cream. The method comprises the following preparation processes: extracting polygonatum sibiricum active ingredients, wherein the extraction temperature of the polygonatum sibiricum active ingredients is 85-90 DEG C, and the extraction time is 2-6 h; performing a polygonatum sibiricum enzyme hydrolysis conversionreaction, wherein the temperature of the polygonatum sibiricum enzyme hydrolysis conversion reaction is 25-40 DEG C, and the reaction time is 1-4 h; performing microporous membrane filtration, wherein the microporous membrane filtration pressure is 0.3-0.5 MPa and the membrane filtration pore size is 1-5 [mu]m; performing reduced-pressure concentration until the solid content is 30%-35%, whereinthe reduced-pressure concentration temperature is 60-75 DEG C and the vacuum degree is -0.06 Mpa to -0.08 Mpa; and performing secondary conversion on the polygonatum sibiricum active ingredients: adjusting the secondary conversion temperature of the polygonatum sibiricum active ingredients to be 85-90 DEG C, performing heat preservation under normal-pressure stirring for 8-12 h, adjusting the vacuum degree to be -0.05 Mpa to -0.07 Mpa, performing reduced-pressure concentration, repeating the above steps until the solid content is 60%-65%, and after the concentration is completed, obtaining thehighly active polygonatum sibiricum cream. The content of the active ingredients such as polygonatum polysaccharide and polygonatum steroid saponin in the highly active polygonatum sibiricum cream prepared by the method provided by the invention is improved by 30% or more than that of a polygonatum sibiricum cream prepared by a conventional method.

Description

technical field [0001] The invention belongs to the fields of medicine, health food and food processing, and particularly provides a preparation method of a highly active sealwort paste. Background technique [0002] Polygonatum sibiricum is a perennial herb of Liliaceae, whose rhizome has been used as medicine. It has a medicinal history of more than 2,000 years. It was first recorded in "Famous Doctors" in Jin Dynasty. Polygonatum is mild in nature and sweet in taste, enters the spleen, kidney, and lung meridian, has the functions of nourishing the kidney and replenishing essence, widening the middle and replenishing qi, nourishing yin and moistening dryness, promoting body fluid and nourishing the spleen, etc. It has been used for a long time for weak spleen and stomach, kidney deficiency, dry cough due to lung deficiency, Treatment of tiredness and fatigue. Modern chemical composition analysis shows that Polygonatum main medicinal components are steroidal saponins, poly...
