preparation example Construction

[0048] The preparation method of the flavonoid compound of the present invention is to use the waste residue after producing rose essential oil as a raw material, and it is obtained through the extraction of extract, organic solvent extraction, MCI decolorization, silica gel column chromatography and high performance liquid chromatography separation steps, specifically as follows: :

[0049] A. Extraction of extract: the waste residue powder after the production of rose essential oil is ultrasonically extracted 2 to 5 times with a solvent, and the quality of the extraction solvent used each time is 2 to 6 times the quality of the waste residue powder, and the extraction time is 30 to 60 minutes each time. The extracts are combined and filtered, the filtrate is concentrated under reduced pressure until just precipitates are precipitated, left to stand for 20 to 60 minutes, and the precipitates are filtered off, and then the obtained filtrate is concentrated under reduced pressur...

Embodiment 1

[0061] The sample of waste residue after the production of rose essential oil comes from Yuxi, Yunnan, and the variety is Damask rose.

[0062] A, medicinal extract extraction: the waste residue powder after producing rose essential oil is extracted 2 times with solvent ultrasonic, the quality of extraction solvent used at every turn is 2 times of waste residue powder quality, each extraction time is 30 minutes, merge extract and filter, The filtrate was concentrated under reduced pressure until just precipitates were precipitated, left to stand for 20 minutes, and the precipitates were filtered off, and then the obtained filtrate was concentrated under reduced pressure to obtain extract a;

[0063] B, organic solvent extraction: in medicinal extract a, add the water that weight is 1 times of medicinal extract a weight, then extract 3 times with organic solvent, the volume of organic solvent used at every turn is identical with water volume, merge organic solvent extraction pha...

Abstract

The invention relates to a flavonoid compound capable of improving cigarette suction throat comfortableness, as well as a preparation method and application thereof, and belongs to the technical field of plant chemistry. The flavonoid compound is separated from waste residue of production of rose essential oil with a distillation method, the compound is named as 5,7-dihydroxy-2'-methoxy-6-methyl-flavone, the English name is 5,7-dihydroxy-2'-methoxy-6-methyl-flavone, the molecular formula is C17H14O5, and the structural formula is as shown in a formula (I) (the formula I is as shown in the description). According to the preparation method, the flavonoid compound is prepared from the waste residue of production of the rose essential oil through the steps of extractum extraction, organic solvent extraction, MCI decoloring, column chromatography on silica gel and high-performance liquid chromatographic separation. The compound is added into a cigarette filter, can coordinate with the tobacco and improve the sweet moistening feeling of the smoke, has remarkable effects of reducing irritation and drying feeling of the throat, and can obviously improve the suction quality of the cigarette.

Description

technical field [0001] The invention belongs to the technical field of phytochemistry, and relates to a flavonoid compound capable of improving cigarette smoking throat comfort and its preparation method and application, in particular to a flavonoid compound extracted for the first time from the waste residue after producing rose essential oil . When the compound is added to the cigarette filter, it can be coordinated with the original aroma of tobacco, has a significant effect on reducing irritation and throat dryness, and can obviously improve the smoking quality of the cigarette. Background technique [0002] Damask rose (scientific name Rosa Damascena , commonly known as Damask rose), also known as Turkic rose, Rosaceae Rosa, a classical garden rose, a cluster of shrubs, native to Syria, and widely planted in France since the 14th century. Damask rose is the main rose variety grown in Bulgaria , double-petaled flowers, the edge of the petals is slightly lighter in colo...
