preparation example Construction

[0048] The preparation method of the hydroxypropyl flavonoids of the present invention is to use the waste residue after the production of rose essential oil as a raw material, and to obtain it through extracting extract, organic solvent extraction, MCI decolorization, silica gel column chromatography and high performance liquid chromatography separation steps. ,Specifically:

[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 pressure to fo...

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 hydroxypropyl flavonoid compound in damask rose waste residues, a preparation method and application thereof, and belongs to the technical field of phytochemistry. The hydroxypropyl flavonoid compound is obtained by separating waste residues from production of rose essential oil, the English name of the compound is 8,2'-dimethoxy-7-(3-hydroxypropyl)-flavone, the molecular formula is C20H20O5, and the structural formula is shown in a formula (I) which is shown in the description. The hydroxypropyl flavonoid compound is prepared by the steps of: adopting the waste residues after production of the rose essential oil as materials, carrying out extractum extraction, organic-solvent extraction, MCI decoloring, silica-gel column chromatography and high-performance liquid chromatography separation. The hydroxypropyl flavonoid compound, the preparation method and the application thereof have the advantages that after the hydroxypropyl flavonoid compound is added intoa cigarette filter tip, the coordination with the natural fragrance of the tobacco can be achieved, the effect of promoting body-fluid production is obvious, the sweet aftertaste of the smoke is obvious, the smoking stimulation of cigarettes also can be reduced and the effect of softening the smoke is obvious.

Description

technical field [0001] The invention belongs to the technical field of phytochemistry, and relates to a hydroxypropyl flavonoid compound in rose waste residue and its preparation method and application, in particular to a hydroxypropyl flavonoid compound extracted for the first time from waste residue after rose essential oil production . When the compound is added to the cigarette filter, it has an obvious effect of promoting body fluid, can increase the sweetness of the smoke, reduces the irritation of cigarette smoking and has obvious effects of soft smoke. 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 color, with a satin-like te...
