example 1

[0008] Example 1: Take 200 grams of 40-mesh red ginseng powder, the content of ginsenoside is 6.58%, the ratio of ginseng and water is 1:3, soak it for 3 hours, send it to the extraction tank, and extract it for the first time at 60°C for 40 minutes, and separate the materials Water content of 50-60% enters microwave radiation, microwave 2450MHz, material thickness 2.5 cm, after 3 minutes of radiation, it is sent to the extraction tank again, and the extraction is activated for the second time at 60°C for 30 minutes, after separation, the combined filtrate is concentrated and dried to obtain a dry paste 70 grams, the measured ginseng total soap content is 16.54%, and the extraction rate of the calculated active ingredients is 87.99%.

example 2

[0009] Example 2: Get 200 grams of clove leaf material (20 mesh), the measured content of protocatechuic acid is 1.8%, soak it with 20 times of water for 2 hours, send it to the extraction tank at 60 ° C, and extract it for 20 minutes, filter it, and then irradiate it with microwaves 3 minutes, the material thickness is 2.5 cm, microwave 2450MHz, sent to the extraction tank again, 60 ° C, 15 times of water to filter for 20 minutes, combined, filtered and dried to obtain 70 grams of dry paste and 125 grams of residue. After testing, the dry paste The content of protocatechuic acid is 4.61%, the content of residual protocatechuic acid is 0.18%, and the extraction rate of active ingredients is 89.64%. , containing 3.06% protocatechuic acid, the residue contains 0.58% protocatechuic acid, and the extraction rate is 67.70%), and the active ingredients are greatly improved.

Abstract

A low-temperature dynamic extraction method of plant active ingredients is completed by selecting materials, cleaning, drying, smashing, infiltrating, dynamic extracting, separating and concentrating. The method is characterized in that: a plant is smashed into powder and sent to an extraction tank for separating after the infiltration, solid-liquid mixture after the separation is re-sent to the extraction tank for extracting for a second time after the microwave radiation. The extraction of the plant active ingredients of the method is more thorough and has high efficiency and significant effect.

Description

technical field [0001] The invention relates to a method for extracting plant raw material components of Chinese patent medicines, health care products, food, etc., especially a method for extracting effective plant components by low-temperature actuation. Background technique [0002] At present, the method of extracting the total active ingredients of plants with water as a solvent is the decoction method. The extraction must be carried out by boiling, and the time is relatively long. The quality standards of most Chinese patent medicines stipulate that "the first time is 3 hours for water decoction, and the second time is 2 hours." , the third time for 1 hour". There are also only the first two times. This method consumes a lot of energy, and the production efficiency is low, especially the high temperature for a long time, so that the total active ingredients of the plant are lost more, and the quality of the target product is reduced. The technology that can extract t...
