Problems solved by technology

[0002] There are many medicines for treating kidney deficiency and low back pain in modern times, but most of them are produced by traditional water extraction and alcohol precipitation process, which takes a long time to extract, consumes a lot of energy during heating and decocting, and the active ingredients cannot be fully extracted. Completely released, causing the waste of medicinal materials, reducing the curative effect and increasing the cost

Abstract

The invention belongs to the technical field of Chinese traditional medicine, and in particular relates to an ultrasonic extraction preparation method of a Chinese traditional medicine preparation for treating lumbago due to the kidney deficiency. The ultrasonic extraction preparation method comprises the following steps of: taking coarse powder of 250g of eucommia ulmoides and 1250g of folium cortex eucommiae, adding water and performing ultrasonic extraction for 30-50 minutes at the extraction temperature of 30-50 DEG C, filtering the extracted liquid, concentrating the filtrate until the relative density of the concentrate is about 1.20-1.30, cooling to room temperature, precipitating by adding 2.8 times of ethanol, filtering, concentrating the filtrate into extract with the relative density of about 1.10-1.15, and adding a proper amount of dextrin and sweetening agent or auxiliary materials to the extract to prepare medicaments. The ultrasonic extraction preparation method provided by the invention adopts the preparation process by an ultrasonic extraction technique, and the active components in the medicines are fully released under the ultrasonic action, thus improving the utilization ratio of the active components, shortening the short extraction time, increasing the yield, improving the product yield and purity, improving the curative effect of the medicament, and maximizing the medicinal value of the medicament.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicines, and in particular relates to a preparation method of an ultrasonically extracted traditional Chinese medicine preparation for treating kidney deficiency and low back pain. Background technique [0002] There are many medicines for treating kidney deficiency and low back pain in modern times, but most of them are produced by traditional water extraction and alcohol precipitation process, which takes a long time to extract, consumes a lot of energy during heating and decocting, and the active ingredients cannot be fully extracted. Release completely, cause the waste of medical material, have reduced curative effect, increased cost. In the current situation where the price of medicinal materials has risen sharply and medicinal materials are in short supply, it is required to use new technological means to extract the active ingredients in medicinal materials as much as possible...
