A novel preparation method for Fupu cold granules and the resulting product

Abstract

This invention relates to a novel preparation method for Fupu Cold Granules made from the traditional Chinese medicinal herbs hibiscus leaves, magnolia bark, tangerine peel, and burdock seeds. The method optimizes the existing water extraction and alcohol precipitation process. During water extraction, this invention employs a series-connected dynamic external circulation system between tanks (the liquid flows out from the bottom of the tank and into the top of the adjacent tank, with a circulation velocity of 3-5 m / s). 3 This invention boasts low manufacturing costs, high throughput, solvent savings, and high extraction efficiency. During alcohol precipitation, a staged precipitation method is employed (first adding 85% recovered ethanol, then adding 95% ethanol, with controlled flow rate) to minimize the loss of active ingredients due to encapsulation. The preparation technology of this invention is reasonable and feasible, significantly improving the transfer rate of active ingredients and production efficiency while reducing production costs, demonstrating good commercial value and application prospects.
