Example Embodiment

[0027] Example 1

[0028] please combine figure 1 , the present embodiment provides a kind of extraction process of the polysaccharide of pomegranate, comprising the following steps:

[0029] S1, pulverize the green money willow leaves to 15-20 mesh to obtain pulverized materials.

[0030] S2, mix the pulverized material in step S1 with hot water at a temperature of 90°C, and perform ultrasonic extraction. The process parameters of ultrasonic extraction are: 90°C, 70W ultrasonic extraction for 45 minutes. Filter to get the leaching liquid. Repeat the hot water ultrasonic leaching three times, and combine the leaching liquid.

[0031] S3, adjusting the pH of the leaching clear liquid obtained in S2 to 4.2, precipitation, and filtration to obtain the first precipitate (mainly protein filter residue) and an acidic clear liquid. The protein filter residue can be used to make bio-organic fertilizer.

[0032] S4, the acid clear liquid obtained in step S3 is decolorized with GK0...

Abstract

The invention provides a cyclocarya paliurus polysaccharide extraction process, which comprises: crushing cyclocarya paliurus leaves, adding hot water, mixing, carrying out ultrasonic constant temperature hot extraction, and filtering to obtain an extraction clear liquid; adjusting the pH value of the extraction clear liquid to 4-4.5 to obtain an acidic clear liquid; decoloring the acidic clear liquid with activated carbon, adsorbing the decolored solution with resin, and eluting with alkaline warm water to obtain an eluent; concentrating the eluent, adding ethanol, standing, and filtering to obtain a second precipitate and ethanol waste liquid; and carrying out vacuum drying on the second precipitate, and removing ethanol to obtain the cyclocarya paliurus polysaccharide. The cyclocarya paliurus polysaccharide extraction process is high in extraction yield, relatively high in purity, convenient for industrial operation and low in cost.

Description

technical field [0001] The invention relates to the field of application technology of Cyclocarya paliurus, in particular to an extraction process of Cyclocarya paliurus polysaccharide. Background technique [0002] It grows in the deep mountains of the Yunnan-Guizhou Plateau. It is a newly discovered rare and rare tree species. It has powerful medical effects. It is mainly used to make tea and make tea as tea. It can cure arteriosclerosis, diabetes and other cardiovascular and cerebrovascular diseases. It has a good curative effect . Money willow is known as the giant panda in the plant kingdom, and it only exists in China. [0003] Patent document CN112568437A discloses a method for extracting selenium polysaccharide from selenium-enriched Cyclocarya paliurus and the selenium polysaccharide obtained by the extraction method and its application. The technical route disclosed in this patent document is to extract the selenium polysaccharides in selenium-enriched Cyclocarya...
