Abstract

The invention provides a volatile oil clathrate and a preparation method thereof. The volatile oil clathrate is prepared from a volatile oil extracted from fructus aurantii and rhizoma cyperi (roasted) in the mass ratio of 10: 10. The preparation method provides a volatile oil beta-cyclodextrin clathration method and related parameters thereof; due to the use of the method, the extraction ratio of the volatile oil is high; the method is used for the clathration of a volatile oil in Qi-stagnation stomachache treating granules and form-changing preparations thereof, and is capable of remarkably increasing the utilization rate of the volatile oil, preventing the volatile oil from volatilizing or deteriorating due to oxidization in the production and storage processes of drugs, and as a result, the stability of the drugs are improved and then the curative effects of the drugs are improved. The invention also provides a preparation method of the Qi-stagnation stomachache treating granule and form-changing preparations thereof.

Description
