Abstract

The invention discloses a method for preparing melaleuca alternifolia volatile oil microcapsules and application thereof. The method comprises the following steps: dissolving beta-cyclodextrin and Arabic gum in water to form a wall material solution; stirring and adding an emulsifier monoglyceride and melaleuca alternifolia volatile oil in the solution, and homogenizing to obtain emulsified liquid; homogenizing the obtained emulsified liquid at high pressure and then spray-drying to obtain the melaleuca alternifolia volatile oil microcapsules. The method is simple and easy to operate, and the prepared microcapsules are high in stability, good in solubility and good in embedding rate. Pharmacodynamic evaluation proves that the microcapsules have significant effects of diminishing inflammation and alleviating pain and a wide application prospect.

Description

technical field [0001] The invention specifically relates to a preparation method and application of Melaleuca alternifolia volatile oil microcapsules. Background technique [0002] Melaleuca alternifolia is a plant of the genus Melaleuca myrtle. Its fresh branches and leaves can extract essential oil and become tea tree oil. It is the main product of Melaleuca alternifolia, which can inhibit bacteria and relieve itching. And it is effective in the treatment of skin burns. Domestic research on tea tree oil is becoming more and more active, and the quality standard of tea tree oil in my country has been initially established. Tea tree oil has good broad-spectrum antibacterial and health-care effects, and has a pleasant aroma of nutmeg. It is recognized as an excellent natural fragrance, antibacterial agent, and preservative. It is mainly used in daily chemical, pharmaceutical, and food industries. However, domestic studies on other pharmacological effects of Melaleuca alter...
