| titleOfInvention | Flavonoid compound capable of improving cigarette smoking throat comfort and preparation method and application thereof |
| abstract | The invention relates to a flavonoid compound capable of improving the comfort of cigarette suction throat and a preparation method and application thereof, belonging to the technical field of phytochemistry. The flavonoid compound is separated from waste residue after the rose essential oil is produced by a distillation method, and the compound is named as: 5,7-dihydroxy-2' -methoxy-6-methyl-flavone, english name: 5,7-dihydroxy-2' -methoxy-6-methyl-flavanone with molecular formula C 17 H 14 O 5 The structural formula is shown as formula (I): formula (I). The preparation method takes waste residue after the production of the rose essential oil as a raw material and comprises the steps of extract extraction, organic solvent extraction, MCI decoloration, silica gel column chromatography and high performance liquid chromatography separation. The compound added into a cigarette filter can coordinate with the fragrance of tobacco, increase the sweet feeling of smoke, have obvious effect on reducing the stimulation and the dry feeling of the throat, and can obviously improve the smoking quality of the cigarette. |
