Embodiment 1

[0011] Take an appropriate amount of barley seeds, wash them with water, add 3 times of water to grind, and filter through a 100-mesh sieve. Collect the filtrate. The filter residue was refined with 1 times water and filtered with a 200-mesh sieve. After the filtrates were combined, ethanol was added while stirring until the ethanol content reached 70%. After standing for 12 h, the precipitate was collected. An appropriate amount of 80% ethanol was added to the precipitate, stirred and allowed to stand for 12 h, and the precipitate was collected. The precipitate was washed 3 times with an appropriate amount of absolute ethanol, and dried to obtain the barley polysaccharide.

[0012] The color of the obtained barley polysaccharide is light grayish brown, and the total sugar content is 65%.

[0013] Determination method of total sugar content: Precisely take an appropriate amount of anhydrous glucose reference substance, weigh it accurately, add water to make a solution cont...

Abstract

The invention relates to a preparation method of polysaccharide by taking a vaccaria segetalis seed as a raw material. The vaccaria segetalis polysaccharide is prepared by taking the vaccaria segetalis seed as the raw material, adding water to grind into slurry, filtering slag from the slurry and carrying out alcohol precipitation. The method has the characteristics of simple technology, low equipment requirement, easiness in operation, low energy consumption and low cost.

Description

technical field [0001] The invention relates to a method for preparing barley polysaccharides using barley seeds as raw materials, and belongs to the field of plant active ingredient extraction and processing. Background technique [0002] Oatmeal ( Vaccaria hispanica ) is a plant of the family Caryophyllaceae, and its seeds are mainly used as medicine. The traditional Chinese medicine name of barley seed is Wangbuliuxing, also known as Jingonghua, Jianjinhua, Jinscissors, Calendula Yintai, Mailanzi, etc. It is mostly used in traditional clinical practice for "three links", that is, opening the meridian, Tongru, Tonglin. Barley polysaccharide is one of the important active ingredients in barley, which has a good therapeutic effect on lower urinary tract symptoms. In the existing research and patent documents, the preparation method of the polysaccharides of barley cabbage all adopts the traditional water extraction and alcohol precipitation process. Using this process re...
