Isoflavones such as rotinone are used as insecticides, and chalcones are used as sweeteners. Methods for separating these flavonoids from other components in plant extracts include a method that utilizes partition between liquid phases, a method that uses fractional precipitation, and a method that uses an adsorbent. is being implemented. In particular, the method using an adsorbent is a good method for obtaining highly pure flavonoids.
Resins such as polyamide and polystyrene, normal phase type silica gel, and reverse phase type silica gel are used. However, the above-mentioned adsorbents are expensive, require associated equipment, and involve many steps. On the other hand, activated carbon is an inexpensive adsorbent that strongly adsorbs flavonoids. However, there is no known good method for selectively desorbing and recovering flavonoids, and this method is used to remove unnecessary flavonoids such as naringin and hesveridin, which are the cause of the bitter taste of citrus juice. It's just that.

イドの製法である。(Means for Solving the Problems) The method for producing flavonoids of the present invention is characterized by treating a plant extract containing flavonoids with activated carbon, and desorbing the adsorbed flavonoids with an alkaline solution.

タノール等が用いられる。The plant extract containing flavonoids may be a crude extract extracted with water, an organic solvent, or a mixed solvent thereof, or a partially purified fraction thereof. Water or any organic solvent can be used for adsorption onto activated carbon, but in order to achieve sufficient adsorption of flavonoids, it is preferable to carry out the adsorption in a mixed solvent of water and alcohol. At this time, low polar insoluble matter is removed by filtration. In addition, since the adsorption power differs depending on the polarity of the target flavonoid, the amount of water
Consider the composition of alcohol. As the alcohol, ethanol, methanol, propanol, isopropanol, butanol, etc. are used.

~100% ethanol is used. As the activated carbon, those made from coconut shell 2 coal, wood, pitch, petroleum carbon, etc. can be used, and powder is preferable, but granular forms may also be used.
添加する活性炭の量は抽出物中の予想される総フラボン
含量に依存するが、通常総フラボン量の2倍〜10倍で

30m1n撹はんした後、オリバーフィルター等でろ過
しさらに使用した水lアルコール混合溶媒で洗浄する。The amount of activated carbon added depends on the expected total flavone content in the extract, but is usually between 2 and 10 times the total flavone content. The solution containing activated carbon is heated at room temperature or under cooling for 10~
After stirring for 30ml, the mixture is filtered using an Oliver filter and washed with the used water/alcohol mixed solvent.
この工程で糖類やサポニン等を除去することができる。Sugars, saponins, etc. can be removed in this step.

囲で使用でき、脱着させるフラボノイドの極性に対応し
てこれにアルコールを加えた脱着液を調製する。Alkali such as caustic soda, ammonia, and alkylamines can be used for desorption of flavonoids, but a dilute ammonia aqueous solution is most suitable in consideration of removal of the alkali after desorption. The concentration of alkali can be used in the range of 0.1% to 5%, and a desorption solution is prepared by adding alcohol to this in accordance with the polarity of the flavonoid to be desorbed.
例えば、フラボン配糖体の場合には0.5〜5%アンモ
ニアを含む20〜50%エタノール水溶液、フラボンモ
ノマーやビスフラボンの場合にはさらにアルコール濃度
の高い水溶液を用いることができる。For example, in the case of flavone glycosides, a 20-50% ethanol aqueous solution containing 0.5-5% ammonia can be used, and in the case of flavone monomers and bisflavones, an aqueous solution with an even higher alcohol concentration can be used.
また、これら比率の異なる脱着液を組み合わせることに
よりフラボノイド混合物を分離することも可能である。It is also possible to separate flavonoid mixtures by combining desorption liquids with different ratios.
使用後の活性炭は水洗いしてアルカリを除去したのち再
生することができる。Activated carbon after use can be recycled after being washed with water to remove alkali.

Wash the activated carbon with the same solvent. Next, the activated carbon is washed with a 40% aqueous ethanol solution containing 1% ammonia to desorb flavonoids, and the resulting filtrate is concentrated to obtain crude rutin. By recrystallizing this from 20% ethanol, 2.4 g of rutin is obtained.

Subsequently, it is immediately washed with a 40% aqueous ethanol solution containing 2% ammonia, and the purified liquid is concentrated to obtain a crude flavonoid fraction. Flavonoids, which were 6% in the 60% ethanol extract, are concentrated to 33% in the crude flavonoid fraction.
