Example Embodiment

[0020] Example 1.

[0021] Taking the extraction of astragaloside IV as an example, the effect of the field strength of the high-voltage pulsed electric field on the extraction is explained in detail.

[0022] After the astragalus was crushed, it was added to a 50% ethanol solution to prepare a mixed solution with a material-to-liquid ratio of 1:200. Divide this test into 8 groups, and the test numbers are A1, A2, A3, A4, A5, A6, A7, A8. In addition to the above 8 groups of samples, the A1 sample was leached according to the current conventional process, and the other 7 groups of samples were processed by high-voltage pulsed electric field. The processing conditions are as follows:

[0023] A2: Field strength 5kV / cm, 1 pulse; A3: Field strength 20kV / cm, 1 pulse; A4: Field strength 40kV / cm, 1 pulse; A5: Field strength 60kV / cm, 1 pulse; A6: Field strength 80kV / cm, 1 pulse; A7: Field strength 100kV / cm, 1 pulse; A8: Field strength 125kV / cm, 1 pulse.

Abstract

The invention relates to a method for extraction of available composition from biological materials. With biological material such as plant, animal or mushroom as raw material, and the solution such as water or alcoholic solution,citrate solution, weak hydrochloric solution or sodium-hydroxide solution as the solvent, the mixture of said powder raw material and solvent is dealt with high-voltage pulse field in normal temperature to prepare the extract containing available composition of biological material, the field intensity being 5- 125kV/cm and pulse number being 1- 1000. With the method, the extraction time is short, the yield high, the energy consumption small, and also the thermo-sensibility substance in available composition can be effectively protected.

Description

technical field [0001] The invention relates to a method for extracting effective components from biomass materials. Background technique [0002] The biomass material mentioned in the present invention includes plants, animals or fungi. The chemical components contained in biomass materials are complex and diverse, and there are chemical components with significant physiological activities. We call these components effective components. Extraction is the unit operation of separating active ingredients from biomass raw materials, which is directly related to the content of active ingredients in products, and affects internal quality, clinical efficacy, economic benefits and the implementation of GMP. At present, there are many extraction and separation methods, which can be divided into traditional extraction methods and modern extraction methods. [0003] Traditional extraction methods are: solvent extraction, steam distillation, sublimation. These methods can leach vari...
