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

[0016] Cut off blood flow ultrafine pulverization low temperature extraction process:

[0017] Crush the medicinal material of Duoxueliujing into 400-mesh superfine powder, put it into the extraction tank, add water with 3 times the weight of the medicinal material, adjust the pH value of the solvent to 6.0 with acetic acid, stir, turn on steam heating, control the temperature at 70°C, and extract 1 Hours, close the steam valve to stop heating, open the delivery valve to let the feed liquid flow into the centrifuge, open the centrifuge, and separate the slag and liquid. The centrifugal filtrate is concentrated to a relative density of 1.25 (measured at 80°C) by a high-efficiency concentration unit, and dried in vacuum at low temperature ( The temperature is controlled at 70°C) to obtain a dry extract.

[0018] 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 solub...

Abstract

The invention discloses a superfine grinding 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, preserving heat and extracting; (2), performing residue-liquid separation and concentrating the filtrate; and (3), drying the concentrated filtrate in vacuum at low temperature to obtain an extract. By adopting the extraction technology, the effective components of clinopodium polycephalum are retained without damage, the extract yield is increased by more than 25-35% 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 medicines, in particular to a low-temperature extraction method of blood-cutting ultrafine pulverization. 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, no...
