Problems solved by technology
[0002] At present, the traditional preparation process of Astragalus Oral Liquid mainly adopts the method of water extraction and alcohol precipitation. The Astragalus Oral Liquid prepared by this method has many disadvantages: (1) the alcohol precipitation method removes the essential macro and trace elements in the crude drug; (2) The concentration control of the alcohol precipitation method is difficult; (3) The oral liquid processed by the alcohol precipitation is prone to precipitation during the storage period; (4) The alcohol consumption is large, the energy consumption is large, and the money is spent

The invention relates to a preparation method for traditional Chinese medicine oral liquid, in particular to a preparation method for radix astragali oral liquid. The preparation method for the radix astragali oral liquid includes the following steps that 1, polysorbate 80, medicinal alcohol, phospholipid, ethanol, chloroform, lecithin, petroleum ether, diethyl ether, dimethyl sulfoxide, absolute ethyl alcohol, concentrated hydrochloric acid and radix astragali decoction pieces are taken for use; 2, the radix astragali decoction pieces are dried to a constant weight, 1 kg of radix astragali decoction pieces are weighed to be soaked in distilled water overnight, then ultrasonic extraction is performed three times, filtration is performed through gauze, dregs are discarded, water extraction liquor is taken for concentration, the concentration of concentrated liquor is adjusted to 70% through the medicinal alcohol, filtration is performed again after refrigerating and standing, and dregs are discarded, wherein each time of ultrasonic extraction lasts for 30 min, and the temperature needs to be controlled to be 50 DEG C. According to the preparation method for the radix astragali oral liquid, the process is simple, the alcohol content is small after processing, and sediments are not generated after the produced oral liquid is placed for a long time.
