Abstract

The invention relates to a preparation method for an essential oil sustained-release capsule. According to the preparation method, cyclodextrin is wrapped around essential oil, a solubilizer and a cosolvent are added to enhance the solubility of the essential oil in the cyclodextrin, an inorganic powder material of the essential oil is prepared, and finally the essential oil capsule is obtained. The preparation method has the advantages that a process is simple, the production cost is low, an obtained inclusion compound is good in stability, and the requirements of production and application can be further met; the preparation method is simple and high in operability and can further meet the requirements of production and application; the inclusion compound prepared through the preparationmethod is of a nano structure, is beneficial to sustained release and control of the essential oil, and has good physical and chemical stability; and according to the capsule prepared through the preparation method, the volatility of the essential oil can be reduced, the stability can be improved, in addition, the essential oil can be pulverized, so that the essential oil can be conveniently prepared into various dosage forms, and the application range of the essential oil can be expanded.

Description

technical field

[0001] The invention relates to a preparation method of essential oil sustained-release capsules, in particular to the use of cyclodextrin to wrap essential oil molecules to form solid phase powder and then prepare capsules, which belongs to the field of biomedicine. Background technique

[0002] Essential oil is a natural plant essence, usually extracted from plant roots, stems, leaves, flowers, peels or resins, and is a multifunctional aromatic substance with skin care functions. Due to its general volatility, many components are easily lost and oxidized during production, storage and transportation, resulting in changes in the sensory properties of its fragrance components and skin care functions. At the same time, low water solubility also makes it difficult to produce stable, dispersed dosage forms difficulty. Bring inconvenience to its storage and use.

[0003] The inclusion of essential oil is an effective means to solve the above problems. Generall...
