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.
