Problems solved by technology

These methods can leach various active ingredients, but there are following disadvantages: 1) separation, purification difficulty, complex process
2) Heat-sensitive components are easily damaged, and the loss of volatile components is serious
3) The extraction time is long, and the active ingredients are easy to deteriorate
The traditional extraction method is difficult to meet the needs, and the modern extraction technology has the disadvantages of high energy consumption, long extraction time, and high cost.

Embodiment 1

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

[0022] After astragalus is crushed, it is added into 50% ethanol solution to form a mixed solution with a ratio of solid to liquid of 1:200. Divide this test into 8 groups, and the test labels are A1, A2, A3, A4, A5, A6, A7, A8. The above 8 groups of samples except No. A1 sample were leached according to the current conventional process, and the other 7 groups of samples were respectively treated by high-voltage pulse electric field. The treatment 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...
