Abstract

The invention belongs to the technical field of traditional Chinese medicines and particularly relates to a preparation technology and application of folium artemisiae argyi essential oil. The invention provides the preparation technology of the folium artemisiae argyi essential oil. The preparation technology comprises the following steps: crushing folium artemisiae argyi; carrying out enzyme extraction, filtering and water vapor distillation; carrying out ultrasonic extraction on folium artemisiae argyi residues, and filtering; combining, drying and concentrating. The preparation technologyof the folium artemisiae argyi essential oil, disclosed by the invention, has the advantages that the extraction rate of volatile oil can be improved, loss of the volatile oil is reduced, and the safety of the volatile oil is improved. Meanwhile, the folium artemisiae argyi essential oil prepared by the preparation technology disclosed by the invention has a better inhibiting effect on duck serumand DHBV DNA in liver.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine, and in particular relates to a preparation process and application of mugwort essential oil. Background technique [0002] Artemisia argyi is the dried leaf of Artemisia argyi. It is a commonly used Chinese herbal medicine. It has the functions of dispelling cold and relieving pain, warming the meridian to stop bleeding, regulating menstruation and preventing miscarriage, dehumidifying and relieving itching, and dredging the meridian and activating collaterals.
