Description
本発明は、切花を新鮮な状態に長期間保持しうる切花延命剤に関する。 The present invention relates to a cut flower life prolonging agent that can keep a cut flower in a fresh state for a long period of time.
切花を新鮮な状態に保持する為に、従来から様々な方法が採用されている。例えば家庭では水切り、湯上げ、水折り、根元たたきや茎をバーナーで焼く方法等が知られているが、これらの方法はそれぞれの植物に応じて使い分けなければ、十分な効果が得られない。 Various methods have been employed in the past to keep the cut flowers fresh. For example, there are known methods for draining water, raising water, folding water, burning roots, and burning stems with a burner. However, these methods cannot be fully effective unless they are used in accordance with each plant.
また、10円硬貨や漂白剤を花器の水に添加する方法も取られている。これらはそれぞれの抗菌性を利用したものであり、特許文献1のように抗菌作用を利用した切花延命剤も上市されている。また、特許文献2のように、花の萎れの原因の一つであるエチレンの作用を阻害する化合物を用いたものや、水上げを促進するために界面活性剤を含むようなもの等、種々の化学薬品を含んだ切花延命剤が既に上市されている。これらに用いられている抗菌剤やエチレン阻害剤は重金属を含むものが大半であるが、これらの化学薬品の安全性や環境に対しての影響が十分に検証されているわけではない。また、特許文献3のように天然の抗菌剤を利用したものも存在するが、天然の抗菌剤は一般的にその効果が小さい上に、コストも高いことから実用レベルには達していない。
切花を長期間新鮮な状態に保つ事ができ、安全で薬害がなく、かつ安価で廃棄時の環境影響の小さい切花延命剤を提供する。 To provide a cut flower life-prolonging agent that can keep a cut flower fresh for a long period of time, is safe and free from phytotoxicity, is inexpensive and has a small environmental impact upon disposal.
まず本願の請求項1に記載の発明は、グレープフルーツ種子抽出物とヒノキ科植物の抽出物を含有することを特徴とする。 The invention according to claim 1 of the present application is characterized by containing a grapefruit seed extract and an extract of a cypress plant.
グレープフルーツ種子抽出物はグレープフルーツ種子から水またはエタノールやブチレングリコール等の溶剤により抽出された成分を用いる。さらに、グレープフルーツ種子抽出物は果実を種々の食品へ加工した際に廃棄される種子を用いても得ることができる。また、ヒノキ科植物としては、タイワンヒノキ、ヒバ、ヒノキ等が挙げられ、製材時に発生する端材を原料として用いることもできる。これらを水蒸気蒸留して得られる精油、水溶液、ヒノキチオール結晶の一種以上を用いることができる。 Grapefruit seed extract uses components extracted from grapefruit seeds with water or a solvent such as ethanol or butylene glycol. Furthermore, the grapefruit seed extract can also be obtained by using seeds that are discarded when fruits are processed into various foods. In addition, examples of the cypress plant include Thai cypress, hiba, hinoki and the like, and scraps generated during lumbering can also be used as a raw material. One or more of essential oils, aqueous solutions and hinokitiol crystals obtained by steam distillation of these can be used.
これらは共に抗菌作用を有しており、花器の水の腐敗抑制のために用いられるものである。グレープフルーツ種子抽出物又はヒノキ科植物の抽出物を単独で用いた場合、安定した抗菌性を発現させるためには、大量に配合させる必要があり、コストの面から不利であった。そこで、本発明では両者を組み合わせて用いることで、それぞれがごく少ない使用量で十分な抗菌性が得られることを見出した。 Both of these have antibacterial action and are used to control the decay of water in vases. When a grapefruit seed extract or a cypress plant extract is used alone, it is necessary to add a large amount in order to develop stable antibacterial properties, which is disadvantageous in terms of cost. Thus, the present invention has found that by using both in combination, sufficient antibacterial properties can be obtained with a very small amount of each used.
また、グレープフルーツ種子抽出物は花器の水に300ppmを超えて含まれた場合、いけられた切花を腐食し、茎部が変色を起こす場合があり、十分な延命効果を示さない。同様に、ヒノキ科植物においても、花器の水にヒノキチオールとして存在する量が30ppm超えて含まれた場合、切花を腐食し、茎部が変色を起こす場合があり、十分な延命効果を示さない。 In addition, when the grapefruit seed extract is contained in the vase water in excess of 300 ppm, it may corrode the cut flowers and discolor the stem, and does not show a sufficient life-prolonging effect. Similarly, in the cypress family, when the amount of hinokitiol present in the water of the vase exceeds 30 ppm, the cut flowers may be corroded and the stem may be discolored, and the life-spanning effect is not sufficiently exhibited.
すなわち、グレープフルーツ種子抽出物が10ppmから300ppmの範囲で含有され、かつ、ヒノキ科植物抽出物が含まれるヒノキチオール濃度として2ppmから30ppmの範囲で含まれることが望ましい。この範囲を下回ると切花のいけ水として、十分な抗菌性を有さず、切花が短期間のうちに鮮度を失ってしまう。 That is, it is desirable that the grapefruit seed extract is contained in the range of 10 ppm to 300 ppm, and the hinokitiol concentration containing the cypress family plant extract is contained in the range of 2 ppm to 30 ppm. Below this range, it will not have sufficient antibacterial properties as cut water for cut flowers, and the cut flowers will lose their freshness within a short period of time.
本願の請求項2に記載の発明は、請求項1に記載の切花延命剤において、植物栄養素を含有する事を特徴とする。 The invention according to claim 2 of the present application is characterized in that the cut flower life-prolonging agent according to claim 1 contains a plant nutrient.
切花は花器にいけられた時点では生命を維持しており、光合成及び呼吸等の生命維持の活動を行っている。そのため、切花に対して適切な栄養素の補給が必要である。必要な栄養素として、各種のミネラル、アミノ酸、フミン質、糖類が挙げられる。これらが含まれることにより、切花に活力を与え、長期間鮮度を維持させることができる。 Cut flowers maintain their lives when they are put into vases, and carry out life-supporting activities such as photosynthesis and respiration. Therefore, it is necessary to supply nutrients appropriate for cut flowers. Necessary nutrients include various minerals, amino acids, humic substances, and sugars. By containing these, vitality can be given to cut flowers, and freshness can be maintained for a long time.
本願の請求項3に記載の発明は、請求項2に記載の切花延命剤において、植物栄養素が完熟堆肥抽出物であることを特徴とする。 The invention according to claim 3 of the present application is characterized in that, in the cut flower life-prolonging agent according to claim 2, the plant nutrient is a fully matured compost extract.
完熟堆肥抽出物には、適切なバランスの各種ミネラルやアミノ酸やフミン質が含まれている。花器の水に本溶液が含まれることにより、切花に活力を与え、長期間鮮度を維持させることができる。 The fully ripe compost extract contains an appropriate balance of various minerals, amino acids and humic substances. By containing this solution in the vase water, vitality can be given to cut flowers and the freshness can be maintained for a long time.
本願の請求項4に記載の発明は、請求項1から3に記載の切花延命剤において、有機酸を含有することを特徴とする。 The invention according to claim 4 of the present application is characterized in that the cut flower life-prolonging agent according to claims 1 to 3 contains an organic acid.
有機酸の殺菌作用により、花器の水の腐敗を抑制すると共に、切花のエネルギー代謝を促進させ、切花に活力を与え、長期間鮮度を維持させることができる。用いられる有機酸としては、TCAサイクル等のエネルギー代謝経路で生成される有機酸であるクエン酸、イソクエン酸、オキサロコハク酸、α-ケトグルタル酸、コハク酸、フマル酸、リンゴ酸、オキサロ酢酸、酢酸、ピルビン酸のうち一種以上を用いる事が望ましい。 The bactericidal action of the organic acid suppresses the decay of water in the vase, promotes energy metabolism of cut flowers, gives vitality to cut flowers, and can maintain freshness for a long period of time. Examples of organic acids used include citric acid, isocitric acid, oxalosuccinic acid, α-ketoglutaric acid, succinic acid, fumaric acid, malic acid, oxaloacetic acid, and acetic acid, which are organic acids generated in energy metabolic pathways such as the TCA cycle. It is desirable to use one or more of pyruvic acid.
本願の請求項5に記載の発明は、請求項4に記載の切花延命剤において、有機酸が木酢液又は竹酢液のいずれか一方もしくは両方に由来するものであることを特徴とする。 The invention according to claim 5 of the present application is characterized in that, in the cut flower life-prolonging agent according to claim 4, the organic acid is derived from one or both of wood vinegar and bamboo vinegar.
木酢液及び竹酢液には酢酸をはじめ複数の有機酸が含まれている。そのため既知の有機酸を用いた場合と同様、殺菌及びエネルギー代謝の促進により、切花に活力を与え、長期間鮮度を維持させることができる。 Wood vinegar and bamboo vinegar contain multiple organic acids including acetic acid. Therefore, as in the case of using known organic acids, vitality is given to cut flowers by sterilization and promotion of energy metabolism, and freshness can be maintained for a long time.
本願の請求項6に記載の発明は、請求項1から5に記載の切花延命剤において、保湿剤を含有することを特徴とする。 The invention described in claim 6 of the present application is characterized in that the cut flower life-prolonging agent described in claims 1 to 5 contains a moisturizing agent.
保湿剤は切花の乾燥防止のために用いられる。一般的に切花は通常の状態では、その水分が徐々に減少していき、観賞に耐えられないほど乾燥する。保湿剤を用いることで、その乾燥速度を極力抑え、切花に長期間潤いを与え、鮮度を保つことができる。用いられる保湿剤としては、グリセリン、プロピレングリコール、ブチレングリコール等が挙げられ、濃度は花器の水に0.1重量%以上の濃度で含まれるように調製されることが望ましい。なお、安全性および環境への影響を考慮した場合、より望ましくは植物性あるいは動物性由来の保湿剤が望ましい。 A moisturizing agent is used to prevent dryness of cut flowers. In general, in a normal state, a cut flower gradually loses its moisture and dries so much that it cannot withstand viewing. By using a humectant, the drying speed can be suppressed as much as possible, the cut flowers can be moisturized for a long time, and the freshness can be maintained. Examples of the humectant used include glycerin, propylene glycol, butylene glycol and the like, and it is desirable that the concentration is adjusted to be contained at a concentration of 0.1% by weight or more in the water of the vase. In consideration of safety and environmental influences, a humectant derived from plants or animals is more desirable.
また、保湿剤を用いることで、花器の水の切花への浸透性が向上し、切花の鮮度を良好に保つことができる。一般的には花器の水の浸透性向上には界面活性剤が用いられるが、界面活性剤の中には、環境負荷の高いものやその安全性が懸念されるものが存在する。保湿剤を用いることで、これらの使用の抑制することができ、環境影響の低減や、安全性の向上に繋がるという特徴を有する。 Moreover, by using a humectant, the permeability of the vase to the cut flowers of water can be improved, and the freshness of the cut flowers can be kept good. In general, surfactants are used to improve the water permeability of flower vases, but some surfactants have high environmental impact and are concerned about their safety. By using a moisturizing agent, it is possible to suppress the use thereof, and there is a feature that leads to a reduction in environmental impact and an improvement in safety.
本発明による切花延命剤は、切花を新鮮な状態に長期間保持することができ、優れた延命作用を示すとともに、薬害を起こさず、人体に対しても安全でかつ廃棄の際の環境負荷を著しく低減させることができる。さらに、それぞれの抗菌剤がごく低濃度で作用するため、非常に安価に製造可能である。また、従来はそのまま廃棄される生物資源を原料の一部としているため、生物資源の有効活用にもつながるものである。 The cut flower life prolonging agent according to the present invention can keep the cut flowers in a fresh state for a long period of time, exhibits an excellent life prolonging action, does not cause phytotoxicity, is safe for the human body, and has an environmental burden when discarded It can be significantly reduced. Further, since each antibacterial agent acts at a very low concentration, it can be manufactured at a very low cost. In addition, biological resources that have been discarded as they are are part of the raw materials, which leads to effective utilization of biological resources.
次に、実施例に基づいて本発明をさらに詳細に説明するが、本発明はこれらによって制限されるものではない。 EXAMPLES Next, although this invention is demonstrated further in detail based on an Example, this invention is not restrict | limited by these.
