別々の工程で行わざるを得なかった。[Problems to be Solved by the Invention] By the way, some water-soluble components contained in seaweed have been recognized to have properties such as antibacterial activity, and it would be desirable to extract these water-soluble components, however, In the above-mentioned extraction method, only the oil-soluble components can be extracted, and the extraction of the oil-soluble components and the water-soluble components must be performed in separate steps.
【０００５】そこで、本発明は、このような事情を考慮

There is a particular thing.

The organic solvent in the container is removed under reduced pressure, the dissolved organic solvent is coagulated and adhered to the inner surface of the container, the residual liquid in the container is extracted and separated, and the adhered content in the container is extracted with an organic solvent. It was designed to do so.

It is eluted. Then, when the organic solvent is removed from the aqueous solution, the components eluted into the organic solvent do not dissolve in water, so they become insoluble, aggregate, and adhere to the inner surface of the container. Therefore, since the residual liquid after removing the organic solvent, that is, water, contains water-soluble components, the water-soluble components can be extracted by withdrawing this liquid. In addition, if anything adheres to the container,
Since this is an oil-soluble component eluted in an organic solvent, the oil-soluble component can be extracted by dissolving it in an organic solvent. Therefore, oil-soluble components and water-soluble components can be extracted at once.

【実施例】以下、本発明の一実施例を添付図面に基づい

【０００９】図１は本発明に係る方法を説明するための
説明図である。FIG. 1 is an explanatory diagram for explaining the method according to the present invention.
【００１０】先ず、紅藻や褐藻等の海藻を ５■以下に
細かく切り、細化の海藻１を作る。尚、その海藻は、十
分乾燥したものでも生乾きのものでもよい。[0010] First, seaweed such as red algae or brown algae is cut into pieces of 5 cm or less to prepare fine seaweed 1. Note that the seaweed may be sufficiently dried or half-dried.
【００１１】その細化された海藻１を、水溶性を有する
有機溶媒（メタノール、エタノール、酢酸エチル等）の
水溶液例えば８０％メタノール水２と共に、容器内に入
れて、水溶液に海藻を所定時間（例えば約１２時間）浸
漬させる。このとき、海藻を浸漬させながら液を撹拌す
るようにしてもよい。The shredded seaweed 1 is placed in a container together with an aqueous solution of a water-soluble organic solvent (methanol, ethanol, ethyl acetate, etc.), for example 80% methanol water 2, and the seaweed is soaked in the aqueous solution for a predetermined period of time ( For example, about 12 hours). At this time, the liquid may be stirred while the seaweed is immersed.
【００１２】浸漬後、その液をろ過３し、液中の海藻残
渣４を取り除く。その海藻残渣４は、海藻残渣４中に有
用成分が残っているならば、上述の８０％メタノール水
等の水溶液に再度浸漬させて有用成分の溶出に用いても
よい。After soaking, the liquid is filtered 3 to remove seaweed residue 4 from the liquid. If useful components remain in the seaweed residue 4, the seaweed residue 4 may be immersed again in an aqueous solution such as the above-mentioned 80% methanol water to elute the useful components.
【００１３】一方、ろ液５を容器に入れ、この容器内の

利用される。On the other hand, the filtrate 5 is placed in a container, and the gas inside the container is sucked out using an aspirator or the like to reduce the pressure inside the container. Then, when an organic solvent with a low boiling point, 80% methanol water, is used, methanol is vaporized and gradually removed 6 from the aqueous solution. This methanol 7 is coagulated and collected and then reused as an organic solvent for the aqueous solution in which the above-mentioned seaweed is immersed.
【００１４】上述のように、有機溶媒が除去されること

長８し、これが最終的に容器内面に付着する。このとき
、容器を液を中心にゆっくり回転させると、容器内面に
平均化して不溶成分が付着する。As mentioned above, by removing the organic solvent, the proportion of water in the aqueous solution increases, so the components that were eluted in the organic solvent (components that are not soluble in water) become insoluble and form nuclei, and then The insoluble components gradually aggregate and grow on this core, and this eventually adheres to the inner surface of the container. At this time, when the container is slowly rotated around the liquid, the insoluble components are averaged and adhered to the inner surface of the container.
【００１５】そして、有機溶媒の除去が終わると、容器

１０する。[0015] When the organic solvent is removed, most of the remaining liquid in the container becomes water, and this water is extracted and separated into 9 parts. After water separation, a small amount of an organic solvent such as ether, acetone, dichloroethane, etc., ie, an amount sufficient to dissolve the components adhered to the container, is added to the container to extract the adhered components in the container (10).
【００１６】さて、細化の海藻１を８０％メタノール水

の抽出１０を行えることになる。Now, when the thinned seaweed 1 is immersed in 80% methanol water 2 for about 12 hours overnight, the relatively low molecular weight oil-soluble components in the seaweed are eluted by organic solvents such as methanol, and the water-soluble The components are eluted by water. When the liquid is filtered 3 and methanol is removed 6 from the filtrate 5, the components eluted with methanol, that is, the oil-soluble components, coagulate 8 and adhere to the inner surface of the container. As a result, since the residual liquid in the container, that is, water, contains water-soluble components, the water-soluble components can be extracted by extracting and separating the water. Further, since insoluble matter is attached to the container from which the water has been removed, extraction 10 of the oil-soluble components can be performed by adding a small amount of ether to this container to dissolve the attached matter.

収を行える。[0017] Therefore, relatively low molecular weight oil-soluble components and water-soluble components of seaweed can be extracted at once. In addition, by removing the seaweed residue 4 and the organic solvent from the liquid in which the seaweed was soaked, the oil-soluble components and water-soluble components appear in different forms (solid and liquid), so two or more different types of solvents can be used. Since these can be separated without using them at the same time, the useful components of seaweed can be extracted in a simple process. Furthermore, since the organic solvent (methanol) is removed from a solution (filtrate 5) such as methanol water containing some components of seaweed, the organic solvent can be recovered without a separate organic solvent recovery step.
