본 발명은 지베렐린 A4+7을 주제로 하는 도포용 생장조정제 및 그 제조방법에 관한 것이다. 보다 구체적으로, 본 발명은 과실의 비대 및 숙기를 촉진시키는 지베렐린 A4+7가 액상 라놀린과 스테아르산 또는 팔미트산으로 이루어진 혼합 담체에 균일하게 분포되어 있는 도포용 생장조정제 및 그 제조방법에 관한 것이다.The present invention relates to a growth regulator for coating based on gibberellin A4 + 7 and a method for producing the same. More specifically, the present invention relates to a growth regulator for coating and a method for producing the same, wherein gibberellin A4 + 7, which promotes fruit hypertrophy and ripening, is uniformly distributed in a mixed carrier consisting of liquid lanolin and stearic acid or palmitic acid. .

고등식물의 생장호르몬인 지베렐린(gibbrellin)은 각종 과일이나 채소 등의 생장촉진, 무종자화, 숙기억제 등에 사용되며, 그 이성체가 무려 100 여종이 넘는 복잡한 물질이며, 고등식물은 지베렐린 A(gibberellic acid, 이하 GA라 한다)1, 3, 5, 6 및 8 등을 다량 함유하고 있다. 이러한 지베렐린은 식물에 국부적으로 도포되면 그 도포된 부위만 비대하게 생장시키는 특성을 갖고 있어서 기형을 만들 수도 있으므로 고른 생장을 위해서는 일정한 양을 균일하게 도포해 주어야 한다.Gibbrellin, a growth hormone of higher plants, is used for promoting growth of various fruits and vegetables, seedlessness and maturation control, and its isomers are more than 100 kinds of complex substances, and higher plants are gibberellic acid (Gibberellic acid, 1, 3, 5, 6, 8, and the like. These gibberellins have the property to grow only on the applied area when they are applied locally to the plant, which may cause malformations, so even amounts must be uniformly applied for even growth.

종래 과실의 비대와 숙기를 촉진시켜 조기에 수확하기 위하여 과실의 과경부위에 도포하는 지베렐린 함유 생장조정제의 제조방법으로 담체인 라놀린과 바세린에 결정형 분말상태의 GA3 단독 또는 GA3와 GA4+7를 혼합하여 교반하는 방법이 사용되고 있다. 그러나, 아직까지 국내에서 제조하는 제품은 없으며 전량 외국에서 수입하여 과수 농가에 보급하고 있는 실정이다.Conventional method for producing gibberellin-containing growth regulators applied to the fruit area of fruit in order to accelerate the ripening and ripening of fruit, and to mix lanolin and petrolatum as carriers, either GA3 alone or GA3 and GA4 + 7 in crystalline powder. The method to use is used. However, there are no products manufactured domestically yet, and all of them are imported from foreign countries and distributed to fruit farms.

이에 본 발명자는 고등식물이 자체적으로 생산하지 못하거나 극미량만 생산하는 GA4와 GA7을 작물에 직접 공급할 수 있는 생장조정제를 제조한다면 집중적인 효과를 얻을 수 있을 것이라는 점에 착안하여 거듭 연구 노력한 결과, 본 발명을 완성하였다.Therefore, the present inventors have focused on the fact that if they produce growth regulators that can supply GA4 and GA7 directly to crops, which are not produced by themselves or produce only a very small amount of higher plants, the present inventors have made intensive studies. The invention has been completed.

따라서 본 발명의 목적은 고등식물이 자체적으로 생산하지 못하거나 극미량만 생산하는 GA4+7만을 주제로 한 도포용 생장조정제의 제조방법을 제공하는 것이다.Accordingly, it is an object of the present invention to provide a method for producing a growth regulator for coating based on only GA4 + 7, which is not produced by itself or produces only trace amounts of higher plants.

또한 본 발명의 목적은 지베렐린을 혼합 담체에 균일하게 분포시킴으로써 GA4+7가 균일하게 분포된 GA4+7만을 주제로 한 도포용 생장조정제의 제조방법을 제공하는 것이다.It is also an object of the present invention to provide a method for producing a growth regulator for coating based on only GA4 + 7 having a uniform distribution of GA4 + 7 by uniformly distributing gibberellin to the mixed carrier.

또한 본 발명의 목적은 스테아르산 또는 팔미트산을 첨가함으로써 고온기에도 도포액이 과실에 흘러내리지 않는 GA4+7을 주제로 하는 도포용 생장조정제의 제조방법을 제공하는 것이다.It is also an object of the present invention to provide a method for producing a growth regulator for coating, based on GA4 + 7, in which the coating liquid does not flow down to fruit even by adding stearic acid or palmitic acid.

상기 목적을 달성하기 위하여, 본 발명에 따른 GA4+7을 주제로 하는 도포용 생장조정제는 GA4+7을 유효성분으로 하고, 상기 GA4+7이 액상 라놀린과 스테아르산 또는 팔미트산으로 이루어진 혼합 담체에 균일하게 분포된 것을 특징으로 한다.In order to achieve the above object, the growth regulator for coating based on GA4 + 7 according to the present invention is GA4 + 7 as an active ingredient, and the mixed carrier composed of liquid lanolin and stearic acid or palmitic acid is used for GA4 + 7. It is characterized in that it is distributed uniformly.

이하, 본 발명을 구체적으로 설명한다.Hereinafter, the present invention will be described in detail.

본 발명에 따른 도포용 생장조정제의 유효성분인 GA4+7은 고등식물이 자체적으로 생산하지 못하거나 생산한다 하더라도 극미량만을 생산하는 지베렐린으로, 이러한 점을 감안하여 과실 비대 및 숙기 촉진의 효과를 집중적으로 높이기 위하여 기존의 제품과는 차별화시켜 본 발명에서는 GA4+7만을 단독으로 유효성분으로 함유한 것이다.GA4 + 7, the active ingredient of the growth regulator for coating according to the present invention, is a gibberellin that produces only a very small amount even if the higher plant does not produce or produces itself. Differentiated from the existing product to increase in the present invention is to contain only GA4 + 7 as an active ingredient.

본 발명에서 사용하는 담체는 원제인 GA4+7를 균일하게 분포시키는 역할을한다. 지베렐린을 담체에 보다 균일하게 분포되도록 하기 위하여 라놀린에 열을 가하여 액상 라놀린으로 만들어 사용하는 것이 바람직하다.The carrier used in the present invention serves to evenly distribute the original agent GA4 + 7. In order to distribute gibberellin more uniformly to the carrier, it is preferable to make the liquid lanolin by applying heat to lanolin.

구체적인 일례에서, 담체 라놀린에 스테아르산 또는 팔미트산을 혼합한 혼합담체를 사용한다. 융점이 높은 스테아르산(m.p. 70.1 ℃)이나 팔미트산(m.p. 63 ℃)을 첨가함으로써 융점이 낮은 라놀린 담체(m.p. 38 ~ 42 ℃)가 여름철이나 고온기에 흘러내리는 부작용을 방지할 수 있다. 또한, 열대 지방이나 과실 도포 부위에 링을 사용하는 경우에는 스테아르산이나 팔미트산의 함량을 다소 높임으로써 흘러내림 방지효과를 높일 수 있다. 또한, 부수적으로 스테아르산이나 팔미트산은 라놀린에 비해 1/10로 가격이 저렴하므로 제품의 원가 절감효과도 있다.In a specific example, a mixed carrier in which stearic acid or palmitic acid is mixed with a carrier lanolin is used. By adding stearic acid (m.p. 70.1 ° C) or palmitic acid (m.p. 63 ° C) with a high melting point, lanolin carriers (m.p. 38 to 42 ° C) having a low melting point can be prevented from spilling in summer or at high temperatures. In addition, when the ring is used in the tropics or fruit application site, the content of stearic acid or palmitic acid can be slightly increased to increase the anti-dripping effect. Incidentally, stearic acid and palmitic acid are one-tenth less expensive than lanolin, resulting in cost savings.

혼합 담체를 이루는 액상 라놀린과 스테아르산 또는 팔미트산의 혼합 비율은 7 : 3 내지 9 : 1이 적합하다. 스테아르산이나 팔미트산의 양이 이보다 적은 경우에는 본 발명에서 의도하는 흘러내림 방지효과가 잘 나타나지 않고, 이보다 많은 경우에는 너무 굳어서 과경에의 도포 자체가 곤란하다.The mixing ratio of liquid lanolin and stearic acid or palmitic acid constituting the mixed carrier is preferably 7: 3 to 9: 1. If the amount of stearic acid or palmitic acid is less than this, the anti-dripping effect intended in the present invention does not appear well, and if it is more than this, it is too hard to be applied to the excessive diameter.

본 발명에 따른 도포용 생장조정제의 유효성분인 GA4+7은 전체 도포용 생장조정제에 대하여, 0.3 ~ 5 중량%, 바람직하게는 0.3 ~ 2.5 중량%의 양으로 함유되는 것이 바람직하다. 지베렐린의 양이 상기 범위를 넘는 경우에는 과실이 지나치게 비대해져서 열과가 발생할 수 있다.GA4 + 7, which is an active ingredient of the growth regulator for application according to the present invention, is preferably contained in an amount of 0.3 to 5% by weight, preferably 0.3 to 2.5% by weight, based on the total application of the growth regulator. If the amount of gibberellin exceeds the above range, the fruit may become excessively large and fever may occur.

본 발명의 제조방법에서 사용하는 용매는 GA4+7을 용해시키는 역할을 한다. GA4+7는 고체상태로는 담체인 라놀린과 잘 혼합되지 않고 나아가 라놀린에 균일하게 분포되지 않기 때문에 용매에 용해시켜 사용할 필요가 있다. 아세톤은 GA4+7을가장 잘 용해시키고 휘발성(b.p. 56.5 ℃)이 강하여 쉽게 날려보낼 수 있어 적합하다.The solvent used in the production method of the present invention serves to dissolve GA4 + 7. GA4 + 7 needs to be dissolved and used in a solvent because it does not mix well with lanolin as a carrier in a solid state and is not evenly distributed in lanolin. Acetone is suitable because it dissolves GA4 + 7 best and has high volatility (b.p. 56.5 ° C) and can be easily blown away.

이하, 실시예를 들어 본 발명을 더욱 상세히 설명할 것이나, 다음의 실시예는 단지 본 발명의 이해를 돕기 위해 제시되는 예시적 구체예에 불과할 뿐, 본 발명의 보호범위를 이들 실시예로 한정하려는 의도는 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the following Examples are merely exemplary embodiments presented to aid the understanding of the present invention, and are intended to limit the protection scope of the present invention to these Examples. It is not intended.

실시예 1Example 1

먼저 순도 90%의 GA4+7 0.39 g을 용매인 아세톤 2 ml에 용해시킨 다음, 담체로서 라놀린 89.61 g과 스테아르산 10 g의 혼합물을 가온자켓이 있는 혼합탱크에 주입하여 45 ℃로 가온시켰다. 담체인 라놀린이 액상으로 되었을 때 교반을 행하면서 상기 GA4+7 용액을 주입하여 라놀린 담체와 혼합시켰다. 55 ℃에서 감압교반을 행하여 아세톤을 날려보낸 후, 상온으로 온도를 낮추었다. 다음으로, 왁스상태가 될 때까지 계속 교반하여 본 발명에 따른 도포용 생장조정제를 제조하였다.First, 0.39 g of GA4 + 7 having a purity of 90% was dissolved in 2 ml of acetone as a solvent. Then, a mixture of 89.61 g of lanolin and 10 g of stearic acid as a carrier was injected into a mixing tank with a warm jacket and warmed to 45 ° C. When the carrier lanolin became a liquid phase, the GA4 + 7 solution was injected while stirring, and mixed with the lanolin carrier. After stirring under reduced pressure at 55 ° C. to blow off acetone, the temperature was lowered to room temperature. Subsequently, stirring was continued until a wax state was prepared, thereby preparing a growth regulator for coating according to the present invention.

실시예 2Example 2

GA4+7 2.2 g, 라놀린과 스테아르산(stearic acid)를 9 : 1의 비율(w/w)로 혼합하여 제조한 혼합담체 97.8 g 및 아세톤 10 ml를 사용하는 것을 제외하고, 실시예 1과 동일한 방법으로 본 발명에 따른 도포용 생장조정제를 제조하였다.2.2 g of GA4 + 7, 97.8 g of mixed carrier prepared by mixing lanolin and stearic acid at a ratio of 1 to 1 (w / w) and 10 ml of acetone, were used in the same manner as in Example 1. The growth regulator for application according to the present invention was prepared by the method.

실시예 3Example 3

스테아르산 대신 팔미트산(palmitic acid)를 사용하는 것을 제외하고, 실시예 2와 동일한 방법으로 본 발명에 따른 도포용 생장조정제를 제조하였다.Except for using palmitic acid (palmitic acid) instead of stearic acid, the coating growth regulator according to the present invention was prepared in the same manner as in Example 2.

액체 크로마토그래피(HPLC)로 분석한 결과, 본 발명에 따른 도포용 생장조정제의 전 부분에 걸쳐 유효성분인 GA4+7가 균일하게 분포함을 확인할 수 있었다.As a result of analysis by liquid chromatography (HPLC), it was confirmed that the active ingredient GA4 + 7 was uniformly distributed over the whole part of the growth regulator for coating according to the present invention.

본 발명에 따라 종래 GA3과 GA4+7을 혼합사용한 것과 달리, 고등식물이 자체적으로 생산하지 못하거나 극미량만 생산하는 GA4+7만을 단독으로 혼합담체에 균일하게 분포시켜 제조함으로써 보다 집중적으로 과실의 비대 및 숙기 촉진에 기여할 수 있고 여름철 고온기에도 도포액이 과실에 흘러내리지 않는 약제의 제조가 가능하다.Unlike the conventional mixture of GA3 and GA4 + 7, according to the present invention, only higher concentrations of fruit can be produced by uniformly distributing GA4 + 7, which is not produced on its own or produces only a very small amount, in a mixed carrier. And it is possible to contribute to the promotion of maturation, it is possible to manufacture a drug in which the coating liquid does not flow into the fruit even in the summer high temperature.
