Embodiment 1
[0014] The application of Paulownia flower extract in cigarettes is specifically:
[0015] Put the fresh paulownia flowers into a constant temperature vacuum oven at 60°C and fully dry them, then cool them naturally in the oven, and take them out. Weigh 100g, pulverize it with a grinder, add it to a 1000 mL round bottom flask, add 375 mL 95% ethanol and 375 mL petroleum ether, heat and reflux in a water bath for 6 h, stop heating, filter while hot, and filter the residue with 95% The mixed solvent of ethanol and petroleum ether (volume ratio 1:1) was washed three times. After the filtrate was cooled, the solvent was evaporated under reduced pressure to obtain a light red viscous liquid, namely natural Paulownia flower extract.
Embodiment 2
[0017] The application of Paulownia flower extract in cigarettes is specifically:
[0018] Put the fresh paulownia flowers into a constant temperature vacuum oven at 60°C and fully dry them, then cool them naturally in the oven, and take them out. Weigh 100g, grind it into a 1000mL round-bottomed flask, add 750mL of petroleum ether, heat and reflux in a water bath for 4 hours, stop heating, filter while hot, wash the residue with petroleum ether three times, and decompress the filtrate after cooling The solvent is evaporated to obtain a light red viscous liquid, which is the natural Paulownia flower extract.
Embodiment 3
[0020] Put the fresh paulownia flowers into a constant temperature vacuum oven at 60°C and fully dry them, then cool them naturally in the oven, and take them out. Weigh 100g, crush it by grinding, add it to a 1000mL round bottom flask, add 750mL 95% ethanol, heat and reflux in a water bath for 7h, stop heating, filter while hot, wash the residue three times with 95% ethanol, and cool the filtrate , and evaporate the solvent under reduced pressure to obtain a light red viscous liquid, that is, the natural Paulownia flower extract.
[0021] Composition analysis of the tobacco spices (extract) prepared in the above examples: Agilent 7890A-5975C GC / MS (Agilent Technologies Co., Ltd., USA) and 400 nuclear magnetic resonance spectrometer (Varian Corporation, USA) were used to analyze and find that The main ingredients are: glucoside, quercetin, kaempferol, high eriodiction, 4,5,7-trihydroxy-3-methoxyflavone, 5-hydroxy-3,4,7-trimethoxy Flavonone, luteolin, acetin, benzaldehyde, van...
