Problems solved by technology

However, for blood-cut varieties, none of the above methods has much effect
The traditional blood flow extraction generally uses water extraction or alcohol extraction, which has problems such as low ointment yield and destruction of active ingredients.

Embodiment Construction

[0018] Low temperature extraction process of blood flow acid-base method:

[0019] Crush the medicinal material of Duanxueliujing, put it into an extraction tank, add 3 times the weight of water, adjust the pH value to 6.0-6.5 with acetic acid, control the heating temperature at 70°C, and keep warm for 1 hour;

[0020] (2), carry out the separation of slag liquid to obtain filtrate, filtrate;

[0021] (3) Add 3 times the weight of the dregs to water extraction, adjust the pH value to 8.0-8.5 with sodium bicarbonate; control the heating temperature at 70°C, and keep the extraction for 1 hour;

[0022] (4), carry out slag-liquid separation to obtain filtrate;

[0023] (5) Combine the filtrates and dry them in vacuum at low temperature to obtain a dry extract.

[0024] The density of the broken blood flow powder and the soluble substance contained in the solvent of the present invention maintains a very high gradient, so that the soluble substance is continuously dissolved at a...

Abstract

The invention discloses an acid-base low-temperature extraction method for clinopodium polycephalum. The method comprises the following steps: (1), grinding crude medicinal material of clinopodium polycephalum into superfine powder with 350-500 meshes, adding with water being 3 to 5 times of superfine powder in amount, adjusting the PH value to range from 5.0-6.5 by using acetic acid, heating and extracting under heat preservation; (2), performing residue-liquid separation to obtain filtrate; (3), adding the medicinal residue with water being 2 to 3 times of the medicinal residue in amount, adjusting the pH value to range from 8.0-8.5 by using sodium bicarbonate, hearing and extracting under heat preservation; (4), performing residue-liquid separation to obtain filtrate; and (5), merging the filtrates, and drying the mixture in vacuum at low temperature to obtain dry extract. By adopting the extraction technology, the effective components of clinopodium polycephalum are retained without being damaged, the extract yield is increased by more than 35% in comparison with that of a conventional method, and the energy consumption is lowered.

Description

technical field [0001] The invention relates to an extraction process of active ingredients of traditional Chinese medicine, in particular to a low-temperature extraction method of blood flow acid-base method. Background technique [0002] Extraction of traditional Chinese medicine is one of the most critical links in the production of Chinese patent medicine, and various new technologies at home and abroad are constantly emerging. Biological enzymatic hydrolysis technology, ultrasonic-assisted extraction technology, microwave-assisted extraction technology, supercritical fluid extraction technology, ultra-high pressure extraction technology, semi-bionic extraction technology, etc. have come one after another. The application of these modern extraction and separation technologies can overcome the bottleneck problem of traditional extraction and separation technologies to a certain extent, and greatly improve the extraction and separation technologies. However, none of the a...
