Problems solved by technology

Water extraction production, its production process and production equipment are simple, but there are disadvantages such as large water treatment capacity, difficult conventional separation, low product purity, and large energy consumption
The organic solvent method mainly uses 70-95% alcohol-water solvent to extract the raw materials. This process has the advantages of high extraction efficiency, good product quality, and suitable for industrial production. However, the process is complicated, the investment is large, and the product needs to be further purified. refined

Embodiment 1

[0050] Select the whole fruit of acacia with a water content of ≤8%. After cleaning and removing impurities, the impurity rate is ≤0.5%, and does not contain iron impurities; the whole fruit is mechanically crushed with a rod mill, and the seeds are separated, and the seed separation and extraction rate is ≥95% The acacia pericarp after the seeds are separated is pulverized and sieved by a hammer mill to obtain pericarp particles with a particle size of 2 to 3 mm. Use No. 6 extraction solvent oil (Jinling Petrochemical Co., Ltd.) to extract and separate the fat-soluble components in the pericarp. The weight ratio of the extractant to the pericarp is 3.5:1, and the extraction time is 5 hours. The defatted pericarp is extracted with absolute ethanol to separate saponin, the weight ratio of absolute ethanol and defatted pericarp is 4:1, the extraction temperature is 60° C., and the extraction time is 5 hours. The extract was concentrated until the weight ratio of saponin to ethan...

Embodiment 2

[0052] The acacia pericarp after the seeds are separated is pulverized and sieved by a hammer mill to obtain pericarp particles with a particle size of 0.5-2 mm. Use No. 6 extraction solvent oil (Jinling Petrochemical Co., Ltd.) to extract and separate the fat-soluble components in the pericarp. The weight ratio of the extractant to the pericarp is 7:1, and the extraction time is 6 hours. The defatted pericarp is extracted with absolute ethanol to separate saponin, the weight ratio of absolute ethanol and defatted pericarp is 8:1, the extraction temperature is 60° C., and the extraction time is 8 hours. The extract was concentrated until the weight ratio of saponin to ethanol was 1:1, and then crystallized at 15°C. The saponin crystals are filtered through a vacuum filter, washed twice with acetone and dried in a box dryer to obtain the saponin product. The calculated product yield, saponin purity and saponin extraction rate were measured respectively, and the results are sho...

Embodiment 3

[0054] The acacia pericarp after the seeds are separated is pulverized and sieved by a hammer mill to obtain pericarp particles with a particle size of 5-6mm. The fat-soluble components in the pericarp were extracted and separated with petroleum ether, the weight ratio of the extractant to the pericarp was 4:1, and the extraction time was 3 hours. The defatted pericarp is extracted with absolute ethanol to separate saponin, the weight ratio of absolute ethanol and defatted pericarp is 5:1, the extraction temperature is 60° C., and the extraction time is 4 hours. The extract was concentrated until the weight ratio of saponin to ethanol was 1:1, and then crystallized at 15°C. The saponin crystals are filtered through a vacuum filter, washed twice with acetone and dried in a box dryer to obtain the saponin product. The calculated product yield, saponin purity and saponin extraction rate were measured respectively, and the results are shown in Table 1.

Abstract

A process for preparing the gleditschiasaponin used for agricultural chemical, detergent and shampoo features that the absolute alcohol is used for its extraction and separation.

Description

technical field [0001] The invention belongs to the field of forest product chemical industry and applied chemistry, and relates to a preparation process of saponin and its application in pesticides, detergents and shampoos. Background technique [0002] Gleditisia sinensis Saponin, also known as Gleditisia sinensis Saponin, is a pentacyclic triterpenoid saponin composed of basic units such as ligands, sugar bodies and organic acids. The saponin molecule is composed of hydrophilic sugar body and hydrophobic coordination group, so it has various surface active properties such as emulsification, dispersion, wetting, decontamination, and foaming, and is a natural non-ionic Surfactant. In addition, saponin also has obvious anti-inflammatory, anti-penetration ability and anti-inflammatory, expectorant, analgesic, bactericidal, insecticidal and other effects. Therefore, saponin can be used to manufacture various types of emulsifiers, detergents, insecticides or fungicides, etc.,...
