A process for extracting beta-glucosan from oats includes such steps as mixing oats bran with water, stirring at 50-60 deg.C, regulating pH=8-10, adding proteinase, hydrodyzing the protein in oats bran, adding alpha-amylase, treating at 80 deg.C, filtering to obtain clear liquid, ultrafiltering, and freeze-drying.

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.

An active largehead atractylodes saccharide complex is produced through water soaking largehead atractylodes rhizome, organic solvent precipitating, water dissolving the precipitate, dialyzing or membrane separating the supernatant liquid, concentration and drying to obtain coarse product, column chromatographic separation of the coarse product to obtain fine largehead atractylodes saccharide compound. The process is simple and high in yield and is suitable for industrial production. The largehead atractylodes saccharide complex contains polysaccharide in 40-60 wt%, alduronic acid in 15-45 wt% and protein in 10-25 wt% and the polysaccharide includes glucose, galactose, mannose, arabinose and rhamnose. The largehead atractylodes saccharide complex has obvious blood sugar reducing effect and no toxic side effect.

A process for extracting oligomeric saccharide SnS-2 from scrophularia root includes soaking in water, precipitating in organic solvent, dissolving precipitate in water, dialyzing supernatant, membrane separation, concentrating and drying. Its advantages are sure medical action for suppressing cancer and improving immunity, high yield and no toxic by-effect.

The invention relates to an externally used traditional Chinese medicine composition with an emergency skin repair effect. The externally used traditional Chinese medicine composition consists of raw materials including, by weight, from 20 to 30 parts of sophora japonica, from 15 to 20 parts of selfheal, from 10 to 15 parts of purslane, from 10 to 15 parts of radix ophiopogonis, from 10 to 15 parts of radix stemonae, from 10 to 15 parts of giant knotweed rhizome, from 10 to 15 parts of argyi and from 10 to 15 parts of clove. An extraction separation method for a traditional Chinese medicine extract is simple and convenient, purity of obtained products is high, and the quality of the products is greatly improved. The traditional Chinese medicine composition has effects of resisting ultraviolet rays, suppressing and eliminating inflammatory factors caused by ultraviolet irradiation, excellently moisturizing the skin of a user after sun, and the like. Accordingly, the extract can be used as a natural sunscreen raw material applied to sunscreen cosmetics.
