| titleOfInvention | A kind of Chalcone Compounds and its preparation method and application |
| abstract | The invention discloses a kind of Chalcone Compounds and its preparation method and application.Described Chalcone Compounds is separated to obtain from renal lobe beggarweed, and its molecular formula is Cn 20 hn 20 on 5 , there is following structure:n the preparation method of described Chalcone Compounds is with renal lobe beggarweed complete stool for raw material, through medicinal extract extraction, silica gel column chromatography, high pressure liquid chromatography separating step, be specially: with methyl alcohol supersound extraction after renal lobe beggarweed complete stool is pulverized, extracting solution merges, and filter, concentrating under reduced pressure becomes medicinal extract; Medicinal extract silica gel dry column-packing carries out silica gel column chromatography; Be that the chloroform-acetone solution of 1:0 ~ 1:2 carries out gradient elution with volume proportion; Namely the 8:2 part of elutriant obtains described Chalcone Compounds with high pressure liquid chromatography separation and purification further.The present invention proves to have good cytoactive to tobacco mosaic virus (TMV) through test.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. |
