Method for extracting gastrodin by biological enzyme method

Abstract

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.

Description

technical field

[0001] The invention belongs to the technical field of natural product extraction, and in particular relates to a method for extracting gastrodin from Gastrodia elata by using biological enzyme technology. Background technique

[0002] Gastrodia elata (Gastrodiaelata Blame) is a plant of the orchid family. The dry tubers of Gastrodia elata have been used medicinally in my country for more than 2,000 years. , efficacy and clinical application are discussed in great detail. "National Compilation of Chinese Herbal Medicine" summarizes the efficacy of Gastrodia elata as follows: treating high blood pressure, dizziness, headache, crooked mouth and eyes, numbness of limbs, convulsions in children and other diseases. Foreign studies have found that Gastrodia elata has a good preventive and therapeutic effect on senile dementia. In Chinese and Western medicine clinics in my country, Gastrodia elata is mainly used to treat the following diseases: convulsions, convuls...
