Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant fragrance and a plant containing the same, and has been developed especially for the purpose of increasing freshness and aromaticity of fresh flowers and pots.

[0002]

2. Description of the Related Art Fresh flowers and pots are popular all over the world for appreciation. However, in recent years, fresh flowers have been desired not only for appreciation but also for those having high aromaticity due to a mental stability effect and the like. On the other hand, flower varieties have been improved around the world, and a wide variety of flowers can be enjoyed at home and at work. However, at present, the fragrance and freshness fade with time. Because the fragrance component of the flower diverges before flowering,
By the time it reaches the consumer, it naturally becomes weak or faint. In order to compensate for this drawback, Japanese Patent Application Laid-Open No. 10-60472 discloses a plant aroma enhancer containing a fragrance glycoside having an alcohol residue or a phenol residue.
In the issue.

[0003] On the other hand, in order to overcome the shortcomings of volatility and to make water soluble, a method of glycosylating fragrance substances has also been adopted. One of the inventors of the present invention has previously described techniques for chemically and enzymatically converting phenethyl alcohol, which is one of the flavor components of roses, including menthol glycosides, into glucosides by, for example, JP-B-51-105 and This is proposed in Kaihei 10-52297.

[0004]

Perfumery substances of aromatic alcohols such as phenethyl alcohol are highly useful substances with many uses. However, in a normal state with high volatility, the characteristic fragrance disappears in a short time,
Not persistent. In addition, the hydrophilicity may be low,
It was difficult to apply to other fields.

[0005] Therefore, in order to overcome this drawback, generally, a method of converting a fragrance substance into a glycoside has been adopted. Japanese Patent Application Laid-Open No. H10-60472 is one of them, and the glycoside itself does not express an aroma component, but is decomposed by various methods to take advantage of a feature of gradually expressing a fragrance component. One of the inventors has previously proposed two synthetic methods of phenethyl alcohol, a chemical method and an enzymatic method, and found that among them, the aromatic nature of rose was maintained (Japanese Patent Application Laid-Open No. 10-52297).

[0006] However, it is not easy to convert aroma components into glycosides, there are problems of cost and time, the process until commercialization is long, and purified phenethyl alcohol glycosides are hardly soluble in water. I understood that.

[0007] It has been known that when this glycoside is absorbed by a plant, it is decomposed by the action of an enzyme in the body and the fragrance component is emitted. In fact, the present inventors tried to absorb the glycoside into fresh flowers and try to maintain the aroma. However, as shown in Example 8, the glycoside was dissolved in ethanol to dissolve the glycoside. In the ethanol solution, the plants died.

[0008]

The gist of the solution of the present invention is a plant fragrance containing aromatic alcohols, polysaccharides, enzymes and aromatic alcohol glycosides.

Here, aromatic alcohols of 0.1% to 20%
%, Preferably 1% to 10%, polysaccharide 0.1% to 30%, preferably 1% to 20%, enzyme 0.01% to 10%, preferably 0.1 to 10%
2% and the range of 0.001% to 2%, preferably 0.01 to 1%, of the aromatic alcohol glycoside. When the aromatic alcohol is less than 0.1%, the reaction yield of the glycoside is low, and the aroma at the initial stage is small. If it is more than 20%, the yield is low due to the heterogeneous reaction, and the aroma is too strong. With respect to polysaccharides and enzymes, the reaction yield of glycosides is low if it is less than the prescribed value, and if it is more than the prescribed value, dysfunction of fresh flowers is caused.

The most preferred glycoside composition is, for example, about 5% of aromatic alcohol, 10% of polysaccharide, and about 1% of enzyme. Therefore, the reaction solution for converting an aromatic alcohol glycoside into itself satisfies the above-mentioned component range, and since it is an aqueous solution, it has good absorbability to plants.

The aromatic alcohols referred to in the present invention include aliphatic alcohols, aromatic alcohols, chain terpene alcohols, cyclic terpene alcohols, and sesquiterpene alcohols. And aromatic alcohols such as phenethyl alcohol, chain terpene alcohols such as geraniol, cyclic terpene alcohols such as menthol, and sesquiterpene alcohols such as α-Casinole.

The purified phenethyl alcohol glycoside is not very soluble in water. However, this glycoside production reaction is in an aqueous solution, and if this reaction solution is aqueous, it is easily absorbed by plants and does not die. Moreover, since the present reaction solution contains unreacted sugars, fragrance substances, and enzymes, including the reacted glycosides, various advantages have been produced. When used in this state,
At an early stage, the aroma not absorbed by the plant appears,
Several days later, the glycosylated fragrance substance is gradually decomposed by the action of enzymes in the plant, and a fragrance is developed. In addition, sugar is actually used to improve flower life. From the above, it is possible to enhance and maintain the aromaticity of fresh flowers,
Further, freshness can be maintained.

A plant in which the above-mentioned plant fragrance is contained in the tissue of the plant also has the feature of the present invention.
When this plant is a cut flower, it can be obtained by bringing the stem into contact with a water retention material impregnated with a reaction solution for aromatic alcohol glycosylation.

When the plant is a potted plant, since the root is in contact with the soil impregnated with the reaction solution for aromatic alcohol glycosylation, the plant emits an aroma by absorption from the root, And activated. The reaction solution may be impregnated into the flowerpot itself.

[0015] The plant body is a bad incense flower (fila flower),
It is particularly effective if it does not originally have a fragrance and has a large surface area of the foliage, as long as the stem or root is in contact with a water retention material or soil impregnated with a reaction solution for converting an aromatic alcohol glycoside. Is very simple.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to examples, but the present invention is not limited to these examples as long as it is included in the technical idea described so far.

Example 1, Production of various glycosides Maltose and 0.2M caC in 0.2M phosphate buffer solution (pH 6)
combined with l _2, DMSO, added geraniol, linalool, citronellol, a ionol respectively, 50 ° C., 6hr
Stirred. Various glycosides were confirmed on the TLC plate.

Example 2, Aroma from fresh flowers by transportation (Hotty Culture) (Kasaoka City), the solution of Example 1 was impregnated with a moisturizing agent (oasis), and a cut flower set in which cut flowers were inserted. Prepared. This was mailed to Hikari Chemical Laboratory (Okayama City). A blank test was also performed. When the cut flower set mailed the next day was unpacked and subjected to a scent test, all seven panelists confirmed a stronger scent than the blank test.

Example 3, Persistence test of fragrance The cut flower set of Example 2 was allowed to stand, and the fragrance was checked every morning from the next day. Similarly, when seven panelists were asked for judgment, the cut flowers in the blank test could not confirm the scent in 2-3 days. However, a scent could be confirmed from cut flowers impregnated with the solution of Example 1 for one week or more.

Example 4 Influence of Heat The cut flower set of Example 2 was prepared. From the next day, only the cut flowers were taken out and floated in warm water at 40 ° C. for 3 hours every day. As a result of the scent test, all the seven panelists confirmed a stronger scent than the blank test. Furthermore, the cut flowers impregnated with the solution of Example 1 could have a strong scent up to 3 days, and scents could be confirmed for 6 days. However, the fragrance could not be confirmed from the second day on the cut flowers in the blank test.

Example 5 Potted Plant The solution of Example 1 was impregnated into a flowerpot and the test was performed the next day. As a result of the judgment test, all seven panelists confirmed a stronger scent than in the blank test. Also, the fragrance lasted for more than one week.

Example 6: Sustainability of Glycoside and Phenethyl Alcohol Phenethyl alcohol and phenethyl alcohol glycoside are each dissolved in water (both are not completely dissolved), soaked in a water retention agent (oasis), and cut flowers. Was inserted respectively. When the fragrance was determined, the cut flowers impregnated with phenethyl alcohol emitted a considerably strong fragrance for two days from the first day, and thereafter the fragrance could be confirmed until the fourth day. The other cut flower did not show a strong scent, but it did show a scent for more than one week. This is because phenethyl alcohol volatilizes before it is absorbed by the plant and emits a scent at a stretch, whereas glycosides are absorbed by the plant and gradually decomposed by enzymes in the body.

Example 7: Persistence of reaction solution for synthesis of phenethyl alcohol glycoside 5% of unreacted phenethyl alcohol, 10% of maltose,
A reaction solution containing 0.1% of phenethyl alcohol glycoside was impregnated with about 1% of a water retention agent (oasis), and cut roses were inserted as in Example 6. When the scent was determined, a strong scent was released for two days from the first day, and the scent was confirmed for one week or more thereafter. This is considered to be the result of the fact that the glucoside is absorbed by the plant body and gradually decomposed by enzymes in the body while the phenethyl alcohol in the reaction solution is slowly absorbed by the plant and emits a fragrance.

Example 8 The isolated phenethyl alcohol glycoside was dissolved in ethanol, and cut flowers were inserted into the solution. A few days later, the cut flowers wither,
The fragrance peculiar to phenethyl alcohol emerged from the dead cut flowers

[0025]

The plant fragrance of the present invention contains at least aromatic alcohols, polysaccharides, enzymes and aromatic alcohol glycosides, so that the aromaticity of fresh flowers can be enhanced and maintained, and the freshness of fresh flowers can be improved. Retention is significantly improved.

Although the purified phenethyl alcohol glycoside is not very soluble in water and has a low effect, the above-mentioned mixture is effective for maintaining the aromatic freshness for plants due to their synergistic effect.
Furthermore, if it is a reaction solution for the synthesis of glycosides of alcohols,
Because it is an aqueous solution, it is easily absorbed by plants. This reaction solution contains reacted glycosides, unreacted sugars, fragrance substances and enzymes in an appropriate blending ratio, so that purification is not necessary and various advantages are produced, and economical It is a manufacturing method.

A plant in which the above-mentioned plant fragrance is contained in the tissue of the plant also has the feature of the present invention. In the case of cut flowers, the stem is impregnated with a reaction solution for forming an aromatic alcohol glycoside. Since the plant is brought into contact with the moisture retaining material to produce a plant with high aroma and freshness, a product with high marketability can be obtained. It is useful even if the plant is a potted plant, or a fragrant flower (filaflower), for example, haze grass, and can be widely applied regardless of the type and form of the plant. Furthermore, since a plant obtained by cultivating a flower in a medium containing a plant aromatic agent has the same properties as potted plants and cut flowers, there is also an effect that it can be applied to seeds or seedlings.
