The invention discloses a method for improving the content of an effective ingredient epigoitrin in a radix isatidis extract via a biological catalysis method. Compared with the traditional water extraction and alcohol precipitation method, according to the method disclosed by the invention, the content of the effective ingredient epigoitrin in the radix isatidis extract at least doubled by adopting a three-enzyme method, i.e., cellulase, protease and amylase; and in addition, the extract yield is substantially improved.

The invention provides a method for extracting gastrodin by an enzyme method. The method is characterized by comprising the following steps: dissolving rhizoma gastrodiae powder in acetic acid-sodium acetate buffer solution and mixing the two substances evenly; adding complex enzyme into the solution for stirring evenly and enzymolysis; adding alcohol into the mixture to for sufficiently stirring, filtering and deslagging; concentrating extracting solution into extract by a rotary steaming method; and drying the extract to obtain the gastrodin extract. The method has the advantages that as high efficiency and specificity of biological enzyme and mild acting condition, compared with an ultrasonic extracting process, the extracting condition is more convenient, and the equipment is more simplified, so that energy consumption is reduced, and the cost is saved; compared with a hot alcohol refluence extracting process, the extracting condition is simple, the temperature of an extracting system is reduced, so energy consumption of heating is reduced, the pollution to the environment is reduced, a micromolecular drug effect ingredient with thermal volatilization can be remained, and the drug effect of the obtained gastrodin is more complete; and compared with the prior art, the extracting rate is improved by 0.05 to 0.13 percent.

The present invention relates to health product, and is especially one kind of wind dispelling spray for remitting pain and its preparation process. The wind dispelling spray is prepared with eight kinds of Chinese medicinal materials, clematis root, ephedra, safflower, achyranthes root, borneol, etc. It is suitable for remitting pain caused by insect bite, cervical spondylosis, scapulohumeral periarthritis, protrusion of lumbar intervertebral disc, osteoarthritis, etc. It is prepared into high pressure spray form for being sprayed directly to the affected part conveniently, and has no toxic side effect.

The invention relates to a method for extracting radix isatidis extract by the adoption of a biological enzyme method. Amylase and glucoamylase are used for improving a traditional technology, the amylase is used for hydrolyzing rich starch and part of polysaccharide in radix isatidis cell tissue, and the glucoamylase is used for hydrolyzing maltose and dextrin generated by the hydrolyzed amylase to finally obtain glucose. The problem that in the process of alcohol precipitation, gelatinization is prone to occurring, so that dissolving performance is not qualified is effectively avoided, the step of alcohol precipitation in the traditional technology is omitted, compared with the traditional technology, cost is greatly reduced, the relative density of the obtained radix isatidis extract is increased substantially, and the extracting rate of the extract is increased twice or more.

The invention discloses a method for extracting salidroside, comprising the following steps: obtaining rhodiola pulverized material and performing enzymatic hydrolysis to obtain an enzymatic hydrolysis solution; adding the enzymatic hydrolysis solution to an extraction tank in batches to obtain a crude rhodiola rosea Extract, wherein, the treatment method of each batch of enzymatic hydrolysis solution is: adding water and stirring at 35-45 ° C; adding water to the system and heating up to 55-65 ° C; adding water to the system and heating to 75 ° C Stir at ~85°C; add water to the system and stir; drop the temperature of the system to 55-65°C to obtain a filter residue and a primary extraction solution; rinse the filter residue with water and filter the system to obtain a secondary extraction solution, which is combined to form a rhizoma Step 5: Purify the crude extract of Rhodiola to obtain salidroside. The invention can effectively improve the transfer rate of salidroside by pulverizing Rhodiola and then perform enzymolysis first, and then place the enzymolyzed solution at different temperatures for batch extraction, thereby improving the extraction rate of salidroside. .

The invention discloses a preparation method of a herba andrographis and radix helicteris anti-inflammatory tablet, and belongs to the technical field of traditional Chinese medicine preparations. Theherba andrographis and radix helicteris anti-inflammatory tablet is prepared from herba andrographis dry extract containing herba andrographis total lactone and radix helicteris dry extract. The herba andrographis and radix helicteris anti-inflammatory tablet has the beneficial effects that radix puerariae starch is mainly adopted as an auxiliary material, a bonding function can be achieved, andthe pharmaceutical effect of herba andrographis and radix helicteris medicine can be increased; by adding a dry powder mixture of herba andrographis and radix helicteris into pre-prepared starch pureein the end, the dissolution speed after a tablet is taken can be quickened; by adding corn starch in herba andrographis and radix helicteris starch puree in the end, the gelatinization degree of thecorn starch can be reduced, and the disintegration speed after the tablet is taken can be increased; as a whole, an absorption effect of the medicine in the body of a patient can be effectively increased; the adopted herba andrographis dry extract is ultrasonically extracted under an appropriate temperature by adopting ethanol in appropriate ratio and appropriate concentration after baking under the appropriate temperature and is then subjected to impurity removing and concentration, the extraction rate of andrographolide can be effectively increased, the purity can also be increased, and thequality and the production efficiency of a product are greatly increased.

The invention relates to the field of traditional Chinese medicine modernization, in particular to a preparation method and a detection method of a standard decoction of psoraleae. The preparation method of the psoralen standard decoction of the present invention comprises the following steps: taking the psoralen medicinal material, decocting it with water, and filtering to obtain a filtrate; concentrating and drying the filtrate, and then freeze-drying, and the freeze-drying is divided into three stages: a. Pre-freezing: pre-freezing temperature is -50°C to -45°C; b. Primary drying: drying temperature is -30°C to 0°C; c. Secondary drying: drying temperature is 5 to 25°C to obtain psoralen Standard decoction, the paste rate of the standard decoction of psoralen is high, after 6 months of accelerated stability test, the content is relatively stable, the water content is relatively stable, moisture absorption is resistant, and no impurity components are produced; The method for the total content and total transfer rate of lipin and isopsoralen has good specificity, good repeatability and good stability. The characteristic map method of the present invention adopts the super high phase liquid phase, the method is simple, the detection time can be greatly shortened, and the production efficiency can be improved.
