Abstract

PURPOSE:To enhance safety, stability and the long acting property of effect, by using the saponin-containing extracted component, which is obtained by applying extraction treatment to the underground part of Ruscus aculeatus L. using an extraction solvent such as water, a hydrophilic org. solvent or water-containing hydrophilic org. solvent, as an effective component. CONSTITUTION:The underground part of Ruscus aculeatus L. is immersed in an about 5-20 time amount of water or a hydrophilic org. solvent such as methanol, ethanol or acetone or a mixture of both of them and pref. heated to about 40-80 deg.C. Saponin extracted by this method is used as an effective component of a deodorant. If necessary, purifying treatment such as the removal of a precipitate, decoloring treatment by activated carbon, treatment by a synthetic polymer adsorbent or the like is applied to the extract and the extraction solvent is distilled off and dried to obtain a saponin-containing extract having deodorizing function.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a natural product deodorizer that is effective against various bad odors.

[Conventional technology]

Conventionally, typical deodorizing agents include those that have a deodorizing effect by adsorbing malodorous components, such as activated carbon and cyclodextrin, and those that utilize the masking effect of aromatic components. In recent years, various plants (
For example, it has been reported that extracts from plants of the Camellia family such as camellia and tea have a deodorizing effect, but their active ingredients are tannin compounds, which react with iron ions to develop color or react with proteins to precipitate. Due to its high reactivity, the deodorizing effect tends to decrease and its uses are limited.

[Problem that the invention seeks to solve]

An object of the present invention is to provide a deodorizing agent made of natural products that is safe enough to be ingested, can be used freely, is stable, and has excellent long-lasting effects.

[Means for solving problems]

The present invention, which has succeeded in achieving the above object, uses water, a hydrophilic organic solvent, or a water-containing hydrophilic organic solvent as an extraction solvent to extract Ruscus acnes, a plant belonging to the Liliaceae family.
The purpose of the present invention is to provide a deodorizing agent containing as an active ingredient a saponin-containing extract obtained by extracting the underground part of P. xtus L.).

Butcher's Broom
) or K++!e-Holly is an evergreen shrub that grows mainly in the Mediterranean and North America, and the extract from its underground part has diuretic and anti-inflammatory properties. It is known. This extract contains several types of saponins, including ruscogenin as an aglycone, and it has also been reported that this extract has anti-inflammatory effects. However, there is no report that a saponin-containing extract of Nagiikada has a deodorizing effect.

The underground part of the nagi-kada is washed with about 5 to 20 times the amount of water, a hydrophilic organic solvent (e.g. methanol, ethanol, acetone, etc.)
, or a mixture thereof, preferably from about 40 to
When heated to 80°C, saponin, which is an active ingredient of the deodorizer of the present invention, is extracted. Remove precipitate if necessary,
After performing purification treatments such as activated carbon decolorization treatment and synthetic polymer adsorbent treatment, the extraction solvent is distilled off and dried to obtain a saponin-containing extract that has a deodorizing effect.

This extract can be formulated in any way, but the simplest method is to form the saponin-containing extract into a powder, or into tablets or granules, for use as a deodorizing agent.

Alternatively, it can be dissolved in ethanol or the like to form a liquid or aerosol deodorizer. Depending on the form of the deodorizer, the extract may be used for formulation as is. For example, a polymer excipient such as dextrin or CMC may be mixed with the extract and then dried.

〔Effect of the invention〕

The deodorizing agent of the present invention obtained as described above is effective against a wide variety of odorous substances such as hydrogen sulfide, mercaptans, methyl sulfide, ammonia, and amine compounds, and has a wide range of uses. For example, it can be enclosed in the packaging of food and drinks or medicines, placed in storage containers to prevent changing clothes, toilets, sewage sites, garbage disposal sites, garbage collection sites, fish processing plants, livestock farms, chemical factories, etc. It can be used to suppress bad odors by spraying or installing them in places where bad odors occur.

Furthermore, since the active ingredients of the deodorizer of the present invention are safe enough to be used as internal medicines as described above, they can also be directly mixed into various foods and toothpastes.

For example, it can be mixed with chewing gum, candy, etc., and used to produce confectionery that has a breath odor removing effect. In this case, the appropriate amount of the saponin-containing extract is about 0.001 to 10%.

〔Example〕

The present invention will be explained below with reference to Examples. Incidentally, the sensory evaluation of odor in each case was carried out by five expert experts according to the following evaluation criteria.

I can't detect the odor l There's a slight odor 2 I can tell what the odor is 3 There's an odor that can be easily detected 4 There's a strong odor The mixture was extracted under reflux for 2 hours at 80°C. The resulting extract was filtered and concentrated under reduced pressure to remove ethanol. When the obtained concentrate was freeze-dried, 400 g of saponin-containing extract was obtained (this is referred to as deodorizing agent A).

Next, 100 g of the above saponin-containing extract was dissolved in 11 water and passed through a column packed with 11 synthetic adsorption resin Amberlite XAD7 at SVI/Hr. After that, water 1
The column was washed with lice, and then 85% methanol 31 was passed through it to obtain a desorption solution. This was concentrated to dryness under reduced pressure to obtain 25 g of purified saponin fraction (this will be referred to as deodorizing agent B).

0 of the deodorizing agent A and deodorizing agent B obtained as described above.
．． A 1% solution (solvent = 50% ethanol) was prepared and the 1+al thereof was placed in a 20ml sample bottle along with 25ppa methyl mercaptan sodium aqueous solution 11, capped and shaken several times.

After mixing, a sensory evaluation of the deodorizing effect was performed. As a control, a similar mixture of 1 ml of 50% ethanol and 25 ppm sodium methyl mercaptan aqueous solution 11 was used, and its sensory evaluation was rated as 5. The test results were as follows.

Example 2 <5g of garlic was sliced, dried, kneaded well in a mortar with a small amount of water, added 200ml of water, mixed well, and filtered through gauze to obtain 180+*l of extract. . A deodorization test was conducted on 1ml of this extract, which has a strong garlic odor.
This was carried out in the same manner as in Example 1. The results were as follows.

Example 3 Chewing gum was produced with or without the addition of deodorizer A according to Example 1 with the following formulation.

Amount added of deodorizer A Amount without deodorizer added Gum base 20% 20% sugar
55 55 starch syrup 25

After smoking, the participants chewed 5 g of the chewing gum for 3 minutes, removed the crumbs, and immediately compared the tobacco odor of their exhaled breath.

The results were as follows.

Example 4 Candy was produced with or without the addition of deodorizer B according to Example 1, using the following formulation.

Amount added of deodorizer B Amount without deodorizer added Sugar 55% 55% starch syrup
