Flavanone compound and application thereof

Abstract

The invention relates to a flavanone compound and application thereof, belonging to the technical field of tobacco chemistry. The flavanone compound is obtained by the following steps: smashing a tobacco rootstalk sample to 30 meshes, then carrying out ultrasound extraction three times with 95% ethanol, and mixing extracting solutions; filtering, and concentrating the mixed extracting solution atreduced pressure to form extract; dissolving the extract with analytically pure methanol and then carrying out primary separation with silica gel column chromatography; further separating with high performance liquid semi-preparative chromatography so as to obtain the compound. The flavanone compound is named as 5-hydroxyl-6-methyl-3',7-dimethoxyl-8-aldehydel-flavanone. The flavanone compound hasthe advantages of low preparation cost and good tobacco mosaic virus resisting activity, and can be used for preparing tobacco mosaic virus resisting active preparations; and according to the invention, a beneficial new way is provided for comprehensive utilization of tobacco resources.

Description

Technical field: The invention relates to a dihydroflavonoid compound and an application thereof, belonging to the technical field of tobacco chemistry. Background technique: Tobacco is one of the most chemical substances among the various plants known to mankind. After decades of research, more than 3,000 individual chemical substances have been identified from tobacco, and many components have not yet been identified. come out. In addition to being used for smoking cigarettes, tobacco can also extract a variety of valuable chemical components from it, and discover leading compounds that are valuable for development. In particular, the roots and stems of tobacco are generally treated as waste from the tobacco leaf production process. Therefore, in addition to being consumed as cigarettes, it is of great significance to strengthen the comprehensive utilization of tobacco and its waste. Flavonoids generally refer to a series of compounds in which two benzene rings (A- and...
