Embodiment 1

[0066] 1) Put 100kg of Banlangen decoction pieces into the extraction tank, then add 800L of drinking water to soak for 1 hour, adjust the pH of the solution to 6.0 with sodium carbonate and acetic acid, then heat to 70°C, then add 400mL of medium-temperature α-amylase (ie 800000U) , stirring at the above temperature for 1 hour;

[0067] 2) Raise the operating temperature of step 1) to 100°C, decoct for 1 hour, and filter the medicinal liquid with a diatomaceous earth filter to obtain medicinal juice;

[0068] 3) Add 600L of drinking water to the medicinal dregs obtained in step 2), heat to 100°C, decoct for 1 hour, and filter the medicinal liquid with a diatomaceous earth filter to obtain medicinal juice;

[0069] 4) Combine the concoction obtained in step 2) and step 3) and put it into a double-effect concentration tank, adjust its pH to 4.0 with sodium carbonate and acetic acid, heat to 60°C, add 200mL of glucoamylase (ie 20000000U) , stirring at the above temperature for ...

Abstract

The invention relates to a method for extracting radix isatidis extract by the adoption of a biological enzyme method. Amylase and glucoamylase are used for improving a traditional technology, the amylase is used for hydrolyzing rich starch and part of polysaccharide in radix isatidis cell tissue, and the glucoamylase is used for hydrolyzing maltose and dextrin generated by the hydrolyzed amylase to finally obtain glucose. The problem that in the process of alcohol precipitation, gelatinization is prone to occurring, so that dissolving performance is not qualified is effectively avoided, the step of alcohol precipitation in the traditional technology is omitted, compared with the traditional technology, cost is greatly reduced, the relative density of the obtained radix isatidis extract is increased substantially, and the extracting rate of the extract is increased twice or more.

Description

technical field [0001] The invention relates to a method for extracting traditional Chinese medicine, in particular to a method for extracting Radix Radix Radix Radix Extract by using a biological enzyme method. Background technique [0002] Banlangen, also known as indigo root, blue indigo root, and indigo root, is a traditional Chinese medicine in my country. It was first recorded in "Shen Nong's Herbal Classic". It has the functions of clearing away heat, detoxifying, cooling blood, and relieving throat. Mumps, sore throat, rotten throat Dansha, big head plague, erysipelas, carbuncle and other diseases. [0003] Over the years, people have conducted a lot of research and discussion on the extraction methods of active ingredients in Chinese medicinal materials, and have explored many extraction methods of traditional Chinese medicines, among which the commonly used method is water extraction and alcohol precipitation. The method is simple to operate, that is, by adding eth...
