Method for changing viscosity of Magnolia extractive

Abstract

The invention relates to a method for changing viscosity of a Magnolia extractive, which comprises the following steps: reflowing and extracting a Magnolia medicinal material by 50 to 80 percent ethanol with amount of 5 to 10 times of that of the Magnolia medicinal material; combining filtrate to obtain an extractum-shaped extractive; or reflowing and extracting the Magnolia medicinal material by water with amount of 8 to 12 times of that of the Magnolia medicinal material, condensing and performing alcohol precipitation of the obtained product to remove sediment and obtain a liquid extractive; adding the liquid extractive to a sorbent, and decompressing and condensing to obtain an extractum; or adding a sorbent in the extractum-shaped extractive, fully and evenly mixing the mixture and performing vacuum drying on the mixture to prepare the Magnolia extractive. In the method of the invention, a medicinal auxiliary material is adopted as the sorbent which is used as a carrier of an active ingredient, and adsorbs the active ingredients and viscous substances of the Magnolia extractive inside auxiliary material particles so as to change the physical property of large external viscosity and ensure the smooth implementation of a preparation molding process.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine preparations, and relates to a method for extracting magnolia bark Chinese medicinal material, more specifically, a method capable of changing the self-viscosity of the magnolia bark extract and the application of the obtained magnolia bark extract in the preparation process. technical background [0002] The research on solid preparations of traditional Chinese medicine has been committed to the research and development of solid preparations of traditional Chinese medicine and the research of key technologies for industrialization. Magnolia officinalis Rehd. et Wils. is a unique and precious traditional Chinese medicinal material in my country, mainly distributed in western Hubei, southwestern Sichuan, southern Shaanxi and southern Gansu; Magnolia officinalis Rehd. etWils) or Magnolia officinalis Rehd.et Wils.Var.biloba Rehd.et wils dry bark, root bark (called root bark), or b...

AI Technical Summary

Problems solved by technology

The viscosity of Chinese medicine extracts is too high, which is not conducive to the concentration, drying and crushing of Chinese medicine extracts, which seriously restricts the subsequent preparation process

During the production process, due to some special properties of traditional Chinese medicine, it is inconvenient or even difficult to produce this variety.

For example, in the extraction of magnolia officinalis, as the amount of solvent in the liquid extract decreases during the concentration process, the viscosity increases accordingly, which causes great difficulty in the production of subsequent preparation processes.
