Description
Technical field
The invention belongs to technical field of phytochemistry, be related to a kind of isopentyl flavone compound in rose waste residue and its
Preparation method and application, and in particular to extract obtained isopentyl flavonoids in the waste residue after a kind of Rosa Damascana from production first
Compound.The compound is added in cigarette filter, can relax stimulation of the flue gas to throat, and energy exciting salivary secretion, oral cavity
There is the sweet effect of aftertaste, improved mouth chamber pleasant impression, and miscellaneous gas can also be covered, lift the suction quality of cigarette.
Background technology
Damask Rose（Scientific nameRosa Damascena, common first names Damask rose）, also known as Tujue rose, rose
Section's Rosa, belong to classic garden rose, bush plant, originate in Syria, started in 14th century widely to plant in France, greatly
Ma Shige roses are the main rose varieties of Bulgaria's plantation, open hose-in-hose, petal edge color is slightly shallow, has as silks and satins
Texture；Purely, the careful fragrance of a flower makes its hat pressure beautiful and fragrant flowers, turns into the top grade in rose for oil, thus is widely cultivated to extract
Rosa Damascana.Rosa Damascana is the essential oil of most expensive in the world, is referred to as " after essential oil ".Except being widely used in food and cosmetic
Outside product, Rosa Damascana is also widely used in perfuming cigarette；There is cigarette after addition Rosa Damascana tobacco to add answering for Rose Essentielle
Blending type feature, jealous abundant sweetness, smoke is pure and fresh light refreshing, and unique enjoyment of graceful fragrance can be brought to consumer.
Rosa Damascana is usually using the fresh rose flower plucked in the morning as raw material, passes through distillation or the method for supercritical extract
Prepare, the yield of Rosa Damascana is extremely low, and the flower of about five tons of weights can only extract two pounds of attar of rose.It is useless after essential oil generation
A large amount of chemical compositions with value of exploiting and utilizing are also rich in slag, such as：Quercitrin, amaroid, tannin, fat oil, organic acid
（Gallic acid）, haematochrome, uranidin, beta carotene etc..Rose waste residue after production essential oil is comprehensively utilized, to comprehensive
Conjunction utilizes resource, and the added value for improving rose processing has important practical significance.
Research shows, outside the routine chemical componentses such as isolating protein, amino acid, sugar, phosphorus, calcium, potassium, after producing Rosa Damascana
Also contain a large amount of secondary metabolites in waste residue, type of compounds include flavones, cumarin, tannin, furans, flavones, Phenylpropanoid Glycosides,
Terpene, alkaloid etc..These compounds have multiple biological activities, in antibacterial, anti-inflammatory, anti-mutation, decompression, clearing heat and detoxicating, town
Quiet, diuresis, anti-oxidant, anticancer, anti-cancer, suppression lipase etc. many aspects have remarkable result.
Flavone compound refers to two phenyl ring with phenolic hydroxyl group（A- and B- rings）Mutually interconnected by central thricarbon atom
A series of compounds formed are tied, its basic parent nucleus is 2- phenyl chromones.Phenol hydroxyl is often connected with flavone compound structure
The functional groups such as base, methoxyl group, methyl, isopentene group.In addition, it is also often combined into glycosides with sugar.The effect of flavones be it is many,
It is a kind of very strong antioxidant, and the ability for preventing oxidation is more than ten times of vitamin E, and this antioxidation can prevent
Degeneration, the aging of cell, can also prevent the generation of cancer.Flavones can improve blood circulation, reduce cholesterol, improve heart and brain blood
Pipe disease.In addition, flavone compound also has prominent improvement sense of taste effect, the Gustatory Representation of some flavone compounds is very
Especially, there is a kind of natural sweet taste after entrance.Flavones contained by olive is exactly that it can be returned the main reason for sweet, and flavones content
It is higher, return it is sweet more obvious, smell is more mellow.A kind of present invention isolated flavonoids from production Rosa Damascana waste residue
Compound, the compound are added in cigarette filter, can relax stimulation of the flue gas to throat, and energy exciting salivary secretion, oral cavity
There is the sweet effect of aftertaste, improved oral cavity pleasant impression, and miscellaneous gas can also be covered, lift the suction quality of cigarette.
