Abstract
The invention discloses a new dibenzocyclooctenes lignans compound, and a preparation method and application thereof. The compound has a structure of a novel general formula (I) and is structurally formed by that after schisandra wilsoniana vine caulis samples are crushed, 70 percent methanol is extracted by ultrasound for three times, extracting solution is merged and concentrated into extractum, the extractum carries out silica gel column chromatography for primary separation, then, efficient liquid semi-preparative chromatography is adopted for further separation, and the required compoundis obtained. The compound carries out antioxidant activity and free radical scavenging activity screening, and experimental results show that the compound shows higher antioxidation and free radical scavenging activity. Meanwhile, the invention provides the application of the compound to cigarette production. The structural formula (I) is shown as the accompanying drawing.
Description
technical field The invention relates to the technical field of cigarette additives, more specifically, the invention relates to a biphenyl cyclooctene lignan compound. At the same time, the invention also relates to the preparation method of the compound and its application in cigarette production. Background technique Lignans are a class of natural compounds formed by the polymerization of two molecules of phenylpropanoid derivatives (ie, C6-C3 monomers). Most of them are in a free state, and a few are combined with sugars to form glycosides and exist in the xylem and resin of plants. , hence the name. It usually refers to its dimers, and a few can see trimers and tetramers. The monomers that make up lignans include cinnamic acid, cinnamon alcohol, propylene benzene, and allyl benzene. Biphenyl cyclooctene-type lignans are unique compounds of Schisandra genus plants. The structure of this type of lignans not only has a biphenyl structure, but also has an eight-membered ...
