| titleOfInvention | Contained xenol compounds and its preparation method and application in a kind of tobacco rhizome |
| abstract | The invention discloses contained xenol compounds (I) and its preparation method and application in a kind of tobacco rhizome.Use methyl alcohol supersound extraction after being pulverized by tobacco rhizome, extracting solution merges, and filter, concentrating under reduced pressure becomes medicinal extract; Medicinal extract silica gel column chromatography just divides; Be that the chloroform-acetone solution of 1:0 ~ 1:2 carries out gradient elution with volume proportion; Namely the 7:3 part of elutriant obtains required xenol compounds with high pressure liquid chromatography separation and purification further.The compounds of this invention structure is simple, and synthetic easily realizes, and the activity of compound is good, can be used as the guiding compound of resisting tobacco mosaic virus. |
