Embodiment 1

[0027] The pretreatment method of the medicinal materials of Gegen Qinlian prescription is as follows:

[0028] (1) Weigh the four medicinal materials of kudzu root, scutellaria baicalensis, berberine rhizome and licorice respectively according to the weight ratio of 8:3:3:2, and chop them into 3cm-5cm;

[0029] (2) Spray and humidify the medicinal material chopped in step 1 until the water content of the medicinal material is 12%;

[0030] (3) Send the medicinal material after humidification in step 2 into a twin-screw extruder for extrusion and puffing, the puffing temperature is 55° C., and stand for 40 minutes.

[0031] (4) Send the expanded medicinal material into an airtight container, fumigate with saturated steam for 15 minutes, and then enter the active ingredient extraction process.

Embodiment 2～6

[0033] In Examples 2 to 6, the water content of the medicinal material after spraying and humidification, expansion temperature, standing time and steam fumigation are adjusted, and other operations are carried out with reference to Example 1.

[0034] The processing parameters of each embodiment are specifically as follows:

Abstract

The invention relates to apretreatment method for medical materials of a Gegen Qinlian (Chinese character) composition. The method comprises a shredding procedure, a spraying humidification procedure, an extruding and puffing procedure and a suffocating procedure. According to the principle, plant fibers of medicinal materials are destroyed through the extruding and puffing procedure, so that the effective parts of the medicinal materials can contact with an extract liquid in a subsequent extraction technology in relatively large area; partial organic matters in the medicinal materials are activated through the suffocating procedure or reach a free state; and when the medicinal materials are extracted, the effective components are relatively easily separated from the medicinal materials and enter the extract liquid. Compared with a traditional method, the effective components of the medicinal materials pretreated by the method provided by the invention can obtain higher extraction ratio under the same extraction technology and condition.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicines, and in particular relates to a pretreatment method for medicinal materials of Gegen Qinlian prescription. Background technique [0002] Gegen Qinlian Decoction is a famous Chinese medicine prescription in my country. It is made by decocting Pueraria 24g, Huangfen 9g, Coptidis 9g, and Licorice 6g.
