Extraction technique of burdock, soja or garlic extract

Abstract

The invention relates to an extracting technique for extractive of burdock, soybean or garlic; the disposed material is added with water and then is placed on a thermostat water bath concussion machine for extracting; the ratio of the material to water is 1: (5 to 20) by weight ratio, the extracting time is 0.5 to 1.5 hours, and the extracting temperature is 50 to 90 DEG C; the mixture liquid is filtered and the filtered liquid can be added with ethanol after being condensed so as to carry out the alcohol precipitation; the calcium deposits can be obtained through anticentripetal so as to obtain the extractive of the burdock, soybean or garlic by cooling and drying. The extracting technique has the advantages of simple and reliable technique, taking water as an extracting agent, and being economical and secure.

Description

technical field [0001] The invention relates to an extraction process of plant extracts, in particular to an optimized extraction process of burdock / soybean / garlic extract, and belongs to the technical field of plant extraction. Background technique [0002] In recent years, plant extracts have been widely used in medicine and agriculture due to their high active ingredients, natural origin, wide range of effects, no residue, and low cost. Studies have found that because the sugars, saponins and other substances in the extracts of burdock, soybean, and garlic have antibacterial and antioxidant effects, they have attracted widespread attention in medicine, animal feed, botanical pesticides, and fertilizers. [0003] Burdock (Arctium lappa L.), also known as Japanese radish, white-skinned ginseng, etc., is a green and pollution-free plant with both medicine and food. After researching the chemical composition of burdock, it is found that burdock is not only rich in protein, a...

Problems solved by technology

It can be seen that the process of extracting the main components in the plant is complicated, which will inevitably increase the extraction cost.

[0007] On the other hand, the temperature, solid-liquid ratio and other parameters involved in the extraction process are designed in a wide range, which affects the extraction efficiency.

The Chinese patent document with the notification number CN1095468C discloses a method for separating and refining soybean isoflavones from soybean meal, the temperature setting range during extraction is 20-60°C, the extraction time is 2-5 hours, and the range of process parameters is too large , resulting in varying extraction efficiencies

In addition, the solvents used in the extraction process are generally organic solvents, which are used in large amounts and are troublesome to recover, and if the recovery is not complete, the use effect of the extract will be affected

For example, in the method for separating and purifying soybean isoflavones disclosed in the U.S. patent document No. US5679806, methanol is used as the extractant and rinse agent. If the recovery of methanol is incomplete, it will not only affect the use of the extract, but also affect harmful to health

Therefore, these extraction processes have certain limitations in promotion and application.
