Problems solved by technology

[0003] In recent years, scholars at home and abroad have done a lot of research on the extraction and separation, purification, structural analysis and drug efficacy of tremella polysaccharides. Among them, the extraction of tremella polysaccharides generally adopts hot water extraction, but the polysaccharide extraction rate of this method is very low

Embodiment 1

[0016] Embodiment 1, white fungus extract and functional test thereof

[0017] The production process flow chart of Tremella extract provided by the invention is as figure 1 As shown, the specific process is as follows:

[0018] At room temperature, mix white fungus: deionized water at a weight ratio of 1:18; soak for 25 minutes, the white fungus will be fully unfolded; wear sterile gloves, remove the root (completely), cut (or shred by hand) until each piece is thoroughly Spread it out and put it into another container; add deionized water (1kg of white fungus plus 100kg of water) according to 100 times the initial weight of white fungus, add NaOH at room temperature to adjust the pH value to 8.5, and measure the pH value of the system every hour after the reaction , keep it stable; constant temperature 90°C, react for 4 hours; about 50°C (not hot), 200-mesh gauze suction filtration until clear and transparent (1-2 times of suction filtration), filter paper once; rotary evap...

Abstract

The invention discloses a tremella extract and a preparation method thereof. The invention provides the method for preparing the tremella extract that after deionized water is used for soaking tremella, a pH value is regulated ranged from 8.5 to 9.0, constant temperature reaction is carried out under the temperature ranged from 85 DEG to 95 DEG, and the tremella extract is obtained after filtering and concentration. In the method, weight ratio of water and the tremella is 1-100:1; the time of the constant temperature reaction is ranged from 3 h to 5 h; the filtering is carried out by using suction filter method in a filtering step; in a suction filter step, suction filter temperature is ranged from 45 DEG to 50 DEG, gauze of 200 mesh to 300 mesh is firstly used to carry out suction filter to cause suction filter liquid to be clear and transparent, and then filter papers are used to carry out the filtering again. The method for preparing the tremella extract does not need organic reagents, and has simple extraction and separation method. The extraction rate reaches up to 81 percent, the product purity can achieve 85 percent, and the product quality has great improvement.

Description

technical field [0001] The invention relates to a tremella extract and a preparation method thereof. Background technique [0002] Hyaluronic acid is a great moisturizer. Many organisms contain polysaccharides similar to hyaluronic acid, such as white fungus. Tremella is a kind of edible fungus and medicinal fungus with high economic value and preciousness in my country. Tremella polysaccharide is the main active ingredient of Tremella (about 60% to 70% of the dry weight of Tremella), which is divided into exopolysaccharide and cell wall polysaccharide. As a natural extract, tremella polysaccharide has moisturizing and anti-oxidant activities, and is an excellent cosmetic additive; in addition, it is also rich in natural colloids, which have a good emollient effect for long-term use. [0003] In recent years, scholars at home and abroad have done a lot of research on the extraction and separation, purification, structural analysis and drug efficacy of tremella polysacchar...
