Embodiment 1

[0021] A process for continuously extracting Polygonatum saponins and Polygonatum polysaccharides, which successively comprises the steps of extracting Polygonatum saponins and Polygonatum polysaccharides,

[0022] The described operation of extracting Polygonatum saponin comprises the following operations:

[0023] a. Soaking and extraction process: Soak Polygonatum powder in ethanol with a volume concentration of 80% for 1 hour, then heat up to 45° C., extract with ultrasonic waves with a frequency of 25 kHz for 1 hour, and suction filter to obtain Polygonatum extract and Polygonatum medicinal residue; Polygonatum powder and volume concentration are the ratio of 80% ethanol to be 1g: 15ml;

[0024] B, extraction process: the ethanol in the Polygonatum extract is reclaimed with a rotary evaporator; the Polygonatum extract after reclaiming ethanol is moved to a separatory funnel, extracted with ether for degreasing 3 times, and the Polygonatum extract after degreasing is satur...

Abstract

The invention discloses a process for continuously extracting polygonatum saponin and polygonatum polysaccharose. The process comprises the extraction procedure of the polygonatum saponin and the extraction procedure of the polygonatum polysaccharose in turn, wherein the extraction procedure of the polygonatum saponin comprises the following procedures: a, extraction procedure, b, leaching procedure, and c, column procedure; and the extraction procedure of the polygonatum polysaccharose comprises the following procedures: d, fat-free extraction procedure, e, alcohol precipitation procedure, f, deproteinization procedure, and g, dialysis procedure. Compared with the prior art, the process of the invention has the advantages that: the polygonatum saponin has a yield which is 3.9 percent of the gross weight of the polygonatum sibiricum and 90.7 percent of that of the saponin of the polygonatum sibiricum and a purity of 95.3 percent, and the polygonatum polysaccharose has a yield which is13.3 percent of the gross weight of the polygonatum sibiricum and 93.2 percent of that of the polysaccharose of the polygonatum sibiricum and a purity of 91.8 percent; the process fully utilizes the polygonatum sibiricum resources and raises the use value of the raw materials; and in addition, the process for continuously extracting polygonatum saponin and polygonatum polysaccharose has the characteristics of high purity, high recovery ratio, low pollution, simple operation and the like.

Description

technical field [0001] The invention belongs to the process of extracting Polygonatum saponins and Polygonatum polysaccharides in particular. Background technique [0002] Polygonatum is a perennial herb, also known as Huangji Lai, Dog Ginger, etc., belonging to Polygonatum Mill. of Liliaceae. Polygonatum contains higher polysaccharides and steroidal saponins. Studies have shown that Polygonatum polysaccharides have the effects of enhancing immune function, anti-tumor, anti-aging, lowering blood fat, improving memory, and anti-virus; and Polygonatum saponins also have a wide range of physiological functions, including improving immunity, lowering blood sugar, anti-tumor, Improve learning and memory, etc. Therefore, the extraction of polysaccharides and steroidal saponins in Polygonatum has important social and economic value. Usually Polygonatum saponin and Polygonatum polysaccharide are extracted separately, can not make full use of raw material Polygonatum. Contents o...
