Extraction method of saponaria officinalis saponin

Abstract

The invention relates to the field of saponin extraction, and specifically relates to an extraction method of saponaria officinalis saponin. A saponin extraction facility adopted by the method comprises a casing, a motor, a breaking module, a screen mesh, a support module, an ultrasonic instrument, a thermostat, and a controller. The breaking module comprises two breaking rollers, which are engaged with each other and rotate in opposite directions. The breaking rollers are mounted on the casing through a rotation shaft. The screen mesh is arranged under the breaking rollers. The rotation shaftis arranged in the casing and is provided with a cam. The cam extrudes the screen mesh downwards intermittently. Due to the screen mesh, non-completely broken saponaria officinalis can not pass through the screen mesh, gradually the screen mesh will be obstructed by the non-completely broken saponaria officinalis; the extraction efficiency is influenced; in order to solve the problem mentioned above, an elastic telescoping rack is arranged to deform the screen mesh, non-completely broken saponaria officinalis will be bounced up to the breaking roller again and broken again, and the extractionefficiency is improved.

Description

technical field [0001] The invention relates to the field of saponin extraction, in particular to a method for extracting saponin. Background technique [0002] Soapwort is also known as stone alkali flower. The alkaloid content of the whole plant of Soapwort is high. Cutting it into pieces and soaking it in water can be used as a mild detergent, softening hard water, and has strong decontamination ability. Soapwort is mainly used for landscaping in China; Saponin, also known as saponin, is a special class of glycosides widely present in the plant kingdom. Its aqueous solution can produce long-lasting soap-like foam after shaking, hence the name. Saponin is widely used in various fields of industrial and agricultural production . [0003] At present, the methods for extracting saponin include water extraction, alcohol extraction, water extraction-precipitation method, water extraction-alcohol extraction method, and resin adsorption method. Especially in the process of extr...

AI Technical Summary

Problems solved by technology

[0003] At present, the methods for extracting saponin include water extraction, alcohol extraction, water extraction-precipitation method, water extraction-alcohol extraction method, and resin adsorption method. Especially in the process of extracting saponin from the whole plant, the roots are not completely pulverized compared with the stems and leaves, and the pass rate of one-time screening is low, which affects the extraction efficiency of saponin

[0004] In the prior art, there are also some technical solutions for the extraction method of saponin. For example, a Chinese patent with the application number CN2017108246179 discloses a method for extracting saponin, which includes the use of ultrasonic-assisted ethanol extraction process, Add extraction auxiliary agent, cooperate with evaporation and concentration, extract saponin from Saponaria, and use the whole plant of Saponaria as extraction raw material to improve the extraction rate of saponin. This technical scheme can improve the extraction rate of Saponin , but this scheme also does not solve the problem of poor crushing effect in the crushing process of the whole plant soapwort
