preparation example Construction

[0049] The preparation method of the flavonoids of the present invention takes the waste residue after the production of rose essential oil as a raw material, and is prepared through the steps of extract extraction, organic solvent extraction, MCI decolorization, silica gel column chromatography and high performance liquid chromatography separation steps, specifically :

[0050] A. Extraction extraction: The waste residue powder after the production of rose essential oil is ultrasonically extracted with a solvent for 2 to 5 times. The quality of the extraction solvent used each time is 2 to 6 times the quality of the waste residue powder. Each extraction time is 30 to 60 minutes. The extracts are combined and filtered, the filtrate is concentrated under reduced pressure until a precipitate just separates out, and the mixture is allowed to stand for 20-60 minutes to remove the precipitate, and then the obtained filtrate is concentrated under reduced pressure to extract a;

Embodiment 1

[0062] The waste residue sample from the production of rose essential oil comes from Yuxi, Yunnan, and the species is Damascus rose.

[0063] A. Extraction extraction: The waste residue powder after the production of rose essential oil is ultrasonically extracted twice with a solvent. The quality of the extraction solvent used each time is twice the quality of the waste residue powder. Each extraction time is 30 minutes. The extracts are combined and filtered. The filtrate was concentrated under reduced pressure until the precipitate just precipitated, and it was allowed to stand for 20 minutes to remove the precipitate, and then the obtained filtrate was concentrated under reduced pressure to extract a;

[0064] B. Organic solvent extraction: add water of 1 times the weight of extract a to extract a, and then extract 3 times with an organic solvent, each time the volume of organic solvent used is the same as the volume of water, and the organic solvent extraction phases are combine...

[0070] The waste residue sample from the production of rose essential oil comes from Yuxi, Yunnan, and the species is Damascus rose.

[0071] A. Extraction extraction: The waste residue powder after the production of rose essential oil is ultrasonically extracted 5 times with a solvent. The quality of the extraction solvent used each time is 6 times the quality of the waste residue powder. Each extraction time is 60 minutes. The extracts are combined and filtered. The filtrate was concentrated under reduced pressure until the precipitate just precipitated, and it was allowed to stand for 60 minutes to filter out the precipitate, and then the obtained filtrate was concentrated under reduced pressure to extract a;

[0072] B. Organic solvent extraction: add water twice the weight of extract a to extract a, and then extract 5 times with an organic solvent, each time the volume of organic solvent used is the same as the volume of water, and the organic solvent extraction phases are comb...

Abstract

The invention relates to a flavonoid compound in damask rose waste residue as well as a preparation method and application thereof and belongs to the technical field of phytochemistry. The flavonoid compound is obtained by separating waste residue generated after producing damask rose essential oil through a distillation method; the compound is named as 5-hydroxy-2',7-dimethoxy-6-methyl-flavone; the molecular formula of the compound is C18H16O5; the structural formula of the compound is expressed as a formula (I) which is shown in the description. The preparation method of the flavonoid compound in the damask rose waste residue comprises the following steps: taking the waste residue generated after producing the damask rose essential oil as a raw material, carrying out extract extraction, carrying out organic solvent extraction, carrying out MCI decoloration, carrying out silica-gel column chromatography and carrying out high-performance liquid chromatography separation to prepare the flavonoid compound. When the compound is added into a cigarette filter, the compound is capable of coordinating with intrinsic fragrance of the tobacco, improving the sweet taste of the smoke and relieving throat irritation after smoking, has an obvious throat-clearing effect, and is also capable of improving the smoking quality of the cigarettes.

Description

Technical field [0001] The invention belongs to the technical field of phytochemistry, and relates to a flavonoid compound in rose waste residue and a preparation method and application thereof, in particular to a flavonoid compound obtained by first extraction from waste residue after the production of rose essential oil. The compound is added to the cigarette filter, can coordinate with the original tobacco fragrance, relieve throat irritation after smoking, has obvious throat clearing and throat clearing effects, and can improve the smoking quality of cigarettes. Background technique [0002] Damascus rose (scientific name Rosa Damascena , Commonly known as Damask rose), also known as Turk rose, Rosaceae Rosa, is a classical garden rose, bushy shrub, 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 are slightly lighter, with a satin-like texture; the pure ...
