Comprehensive extraction method of rhizoma polygonati total saponins and polygahatous polysaccharides

Abstract

The invention discloses a comprehensive extraction method of rhizoma polygonati total saponins and polygahatous polysaccharides. The comprehensive extraction method is characterized by comprising an extraction method of rhizoma polygonati total saponins and an extraction method of polygahatous polysaccharides, wherein the extraction of the rhizoma polygonati total saponins comprises the processes of extracting, degreasing and extracting; the extraction of the polygahatous polysaccharides comprises the processes of water extraction, alcohol precipitation and drying. By adopting the comprehensive extraction method, a by-product which is obtained by extraction of the rhizoma polygonati total saponins at an early stage is used for extracting the polygahatous polysaccharides, so that the medicinal material resource of the rhizoma polygonati is saved, and the utilization rate of the rhizoma polygonati resource is improved. The extraction of the polygahatous polysaccharides at a later stage is not affected by the extraction of the rhizoma polygonati total saponins at the early stage. The rhizoma polygonati total saponins extracted by the method can be used for preparing a rhizoma polygonati wine; the polygahatous polysaccharides can be used for preparing rhizoma polygonati soft capsules, rhizoma polygonati lozenges, rhizoma polygonati instant tea or rhizoma polygonati soft capsule health food.

Description

technical field [0001] The invention belongs to the field of extracting active ingredients of natural medicines, in particular to a comprehensive extraction method of Polygonatum total saponins and Polygonatum polysaccharides. Background technique [0002] Polygonatum is the general term for plants of the genus Polygonatum in the family Liliaceae, also known as Tiger Ginger and Chicken Head Ginseng. Polygonatum has more than 40 species, and there are more than 30 species in my country. According to the difference in the properties of the original plants and medicinal materials, Polygonatum Polygonatum can be divided into three types: Polygonatum Polygonatum, Chicken Head Polygonatum and Rhizoma Polygonatum. Polygonatum Polygonatum contains more polysaccharides and steroidal saponins. Studies have shown that Polygonatum polysaccharides have functions such as enhancing immunity, anti-tumor, anti-aging, anti-virus, lowering blood fat, and improving memory; Polygonatum total sa...

However, there are few reports about the comprehensive extraction of Polygonatum saponins and Polygonatum polysaccharides

Chinese Patent No.: CN101837091A discloses "A Process for Continuously Extracting Polygonatum Saponins and Polygonatum Polysaccharides". This method obtains Polygonatum total saponins from the concentrated solution and Polygonatum polysaccharides from Polygonatum dregs through ultrasonic extraction of ethanol. The method undergoes multiple The purity of Polygonatum total saponins and Polygonatum polysaccharides obtained in the process is relatively high, but the process is complicated and the operation cost is high, which is not conducive to the realization of industrial production
