Problems solved by technology

At present, there are many research reports on the extraction of Artemisia argyi essential oil with supercritical CO2. Chinese patent CN105412192A reports a preparation method of Artemisia argyi volatile oil. Supercritical CO2 extraction is used to obtain the crude Artemisia argyi volatile oil, and then solvent dewaxing is used. The whole process does not refine the essential oil of Artemisia argyi. Subdivision; Chinese patent CN105395593A reports the preparation method of Artemisia argyi volatile oil, the extraction pressure is 15~20MPa, the extraction temperature is 30~35°C, the extraction time is 1.5~2h, the volatile oil of Artemisia argyi is obtained by separation under reduced pressure, and the extraction residue is used to prepare Alcoholic extract, this method has only obtained the primary product of Artemisia argyi essential oil and alcohol extract, and the product added value promotion is not obvious; Chinese patent CN105535261A has reported a kind of Artemisia argyi health-care essential oil and its preparation method, prepares with supercritical CO2 extraction technology Artemisia argyi extract, using Artemisia argyi extract as raw material, prepares Artemisia argyi essential oil through molecular distillation. This supercritical extraction process does not refine the essential oil of Artemisia argyi, and only obtains the volatile oil of Artemisia argyi by molecular distillation.
In addition, there are few studies on supercritical CO2 extraction of total flavonoids and polysaccharides from Artemisia argyi leaves

Abstract

The invention relates to the technical field of the comprehensive utilization of plant resources and particularly relates to a comprehensive utilization method for effective components of wormwood. The comprehensive utilization method comprises the following steps: (S0) preparing wormwood leaves and wormwood roots: separating the wormwood into the wormwood leaves and the wormwood roots; (S1) preparing wormwood leaf raw materials; (S2) extracting wormwood leaf essential oil; (S3) refining a wormwood leaf essential oil extract: carrying out molecular distillation on the wormwood leaf essential oil extract, so as to obtain wormwood leaf essential oil heavy oil and wormwood leaf wax; (S4) extracting wormwood leaf general flavone and crude polysaccharide; and (S5) concentrating, separating andrefining wormwood leaf crude general flavone and crude polysaccharide extracting solutions, so as to obtain the wormwood leaf general flavones and crude polysaccharide. According to a process route, developed by the invention, for comprehensively utilizing the wormwood, the series products of main active components such as essential oil, general flavone, polysaccharide and wormwood root hydrolat in the wormwood can be furthest obtained, so that that the utilization additional value of the wormwood resource is greatly increased.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of plant resources, in particular to a method for comprehensive utilization of active ingredients of wormwood. Background technique [0002] The comprehensive utilization of wormwood can be divided into two parts: wormwood leaf and wormwood root. As a traditional Chinese herbal medicine, Artemisia argyi is widely used in my country. The main active ingredients of Artemisia argyi that have been studied more are essential oils, flavonoids, and polysaccharides. Artemisia argyi essential oil has the effects of warming the meridian to stop bleeding, dispelling cold and relieving pain, preventing miscarriage, antibacterial, analgesic, sedative, and antipyretic; the flavonoids of Artemisia argyi has the effects of eliminating oxygen free radicals, anti-oxidation, anti-tumor, anti-virus, anti-inflammatory and sterilization, and regulating blood lipids. Artemisia argyi polysaccharide is ...
