Abstract

The invention discloses a preparation method and application of an artabotrys hexapetalus essential oil microcapsule. The preparation method comprises the following steps: dissolving chitosan, sodium alga acid and a stabilizer with water, and stirring evenly to obtain a solution A; adding an emulsifier and artabotrys hexapetalus essential oil to the solution A, and homogenizing to obtain a solution B; stirring the solution B at a constant temperature of 40-50 DEG C, and adjusting the pH value to 5.5-6.5 to obtain a compound gel; cooling the compound gel, and then adjusting the pH value to 7-8; and adding a curing agent, reacting and curing to obtain the artabotrys hexapetalus essential oil microcapsule. The obtained artabotrys hexapetalus essential oil microcapsule is in a powder form, is relatively good in water solubility and stability, high in embedding rate, and slow to release, has significant antibacterial activity, and can be applied to the fields such as daily chemicals and medicines.

Description

technical field [0001] The invention relates to a preparation method and application of hawk claw flower volatile oil microcapsules. Background technique [0002] Accordia stenosa is a plant of the genus Accordiaceae of tomato litchi. There are more than 100 species of this genus in the world, and they are mainly distributed in tropical and subtropical regions. In the folk, the stenotic eagle claw flower has been used as a medicinal plant for a long time. It has the functions of clearing away heat and detoxification, reducing inflammation and relieving pain, and can also be used to treat lymphatic tuberculosis of the head and neck. [0003] Volatile oil is a class of active ingredients in traditional Chinese medicine, widely distributed in the plant kingdom, and has a variety of pharmacological activities and a wide range of uses. It is mainly used as flavor in various foods and daily chemical products, and the functional research on volatile oil has not yet been carried ou...
