Problems solved by technology

For example, the equipment investment of supercritical fluid extraction technology and ultrasonic extraction technology is too large. At present, it is limited to the extraction and separation of a small amount of active ingredients or effective parts of traditional Chinese medicine, and there is a lack of pilot scale production and industrial scale production research; macroporous adsorption resin technology exists. Disadvantages such as poor adsorption selectivity, high technical difficulty, and difficult resin regeneration

[0081] Extraction and separation method of bamboo ginseng saponin and polysaccharide of the present invention

[0082] The method steps are as follows:

[0083] A. Extraction of Bamboo Ginseng:

[0084] Weigh 40 parts by weight of 25 mesh bamboo ginseng powder, add water according to the weight ratio of bamboo ginseng powder and water to 15, extract 3 times under micro-boiling conditions, each 2h, filter, and these filtrates are combined to obtain the described bamboo ginseng powder. Radix Ginseng Extract;

[0085] B. pH adjustment

[0086] Use 1mol L -1 Hydrochloric acid aqueous solution and 1mol L -1 Sodium hydroxide aqueous solution adjusts the pH of the bamboo ginseng extract obtained in step (A) to 4.8;

[0087] C. Foam separation:

[0088] Use the foam separation device of the present invention to carry out, the bamboo ginseng extract that step (B) obtains is added in the foam separation tower 6, by the air or nitrogen gas of the high-pressure cylinder 1 by the gas...

Abstract

The invention relates to a method for extracting and separating panax japonicus saponin and polysaccharide from the panax japonicus, which comprises the following steps of: extracting the panax japonicus; adjusting a pH value; performing foam separation; and purifying panax japonicus polysaccharide. The method has the advantages of high separating efficiency, high purity, large extraction volume, low energy consumption, simple device, low cost, no introduction of an organic solvent pollutant, no damage to the structure of the panax japonicus saponin and the like. A surfactant is not necessary to add in the foam extraction process, so the problems of recovery of the surfactant and the pollution caused by the recovery are solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of processing traditional Chinese medicinal materials, and more specifically relates to a method for extracting and separating bamboo ginseng saponins and polysaccharides from bamboo ginseng. 【Background technique】 [0002] Bamboo ginseng saponin is a kind of complex molecule that can produce a large amount of persistent foam after shaking in aqueous solution. It has large molecular weight, high polarity, strong water solubility, and it is difficult to separate and refine. The extraction and separation efficiency of the traditional method is low, the loss of active ingredients is serious, and it may cause environmental pollution. Among the new separation technologies, the application of supercritical liquid extraction, ultrasonic extraction technology, and macroporous adsorption resin separation technology has improved the separation effect of bamboo ginseng saponins, but there are also their own defects. ...
