BACKGROUND OF THE INVENTION Royal jelly, a honeybee product, is a substance called royal milk that causes the differentiation of queen bees.
It is drawing attention as a medicinal and health food. The nourishing tonic effect of raw royal jelly has been recognized in Europe and other countries since ancient Greece and Egypt,
Recently, a wide range of clinical cases of menopausal disorders, skin damage, nervous system, digestive system, etc. have been reported regarding its physiological activity. Generally, the quality of royal jelly is significantly deteriorated and it is extremely difficult to store it. For example, alteration is likely to occur due to oxidation of lipid contained in royal jelly, reaction between sugar and amino acid (aminocarbonyl reaction), enzymatic reaction, and the deterioration of freshness is extremely rapid. When commercializing such raw royal jelly, crude raw royal jelly collected by beekeepers and harvesters is first filtered through a vibrating filter device of about 60 mesh, etc. Remove objects (eg, pebbles, carcasses of bee larvae, etc.). The purified raw royal jelly filtered in this way is commercialized by freezing at extremely low temperature, and sold at a temperature of around -20 ° C. by the way,
Characteristically, this purified raw royal jelly contains about 2% of 10-hydroxy-δ-2-decenoic acid,
It is said that such substances serve as physiologically active substances to promote human health. As described above, 10-hydroxy-δ-in the royal jelly is generally used as a standard for stabilizing the quality of raw royal jelly in which the quality is deteriorated and the freshness is significantly reduced.
The content of 2-decenoic acid is utilized. Therefore, in the quality inspection of the raw royal jelly, 10-hydroxy-δ-2-decenoic acid contained in the raw royal jelly is quantitatively measured.
% Or more of 10-hydroxy-δ-2-decenoic acid is required. It is known that 10-hydroxy-δ-2-decenoic acid is chemically synthesized by various methods. Examples of such a synthesis method include Fray et al., Tetrahedron Letter.

As described above, 10-hydroxy-δ-2-decenoic acid is produced by various synthetic methods or by extraction and purification from raw royal jelly, but these synthetic methods are extremely complicated. Further, in the extraction and purification from raw royal jelly, the content of desired decenoic acid in the raw royal jelly used as a raw material is low, so a large amount of raw royal jelly is required, resulting in extremely high production cost.

By the way, as described above, in the foreign matter removing operation carried out in commercializing raw royal jelly, an extremely viscous liquid substance containing the above-mentioned solid substance remains on the filter. Liquids have hitherto been disposed of as unnecessary impurities having no purpose. However, it was found that in this residue, a portion of 10-hydroxy-δ-2-decenoic acid contained in the crude raw royal jelly before the foreign matter removal treatment operation was transferred in a concentrated state. . The inventors have paid attention to such a fact, and use such a residue as a raw material and subjecting this residue to an extraction treatment with a water-soluble organic solvent to remove almost all of 10-hydroxy-δ-2-decenoic acid contained in the residue. They have found that they can be recovered as those having a relatively high purity, and have reached the present invention. Therefore, the present invention, in the method for producing 10-hydroxy-δ-2-decenoic acid from raw royal jelly, as a raw material, the residue discharged from the foreign substance removal operation performed in commercializing raw royal jelly is used, and the residue The present invention relates to a process for producing 10-hydroxy-δ-2-decenoic acid, which is characterized in that is extracted with a water-soluble organic solvent. Further, before extraction with a water-soluble organic solvent, if the residue is washed with water in advance to remove the water-soluble components present in the residue, 10-hydroxy-δ-2 after extraction with a water-soluble organic solvent
-The purification process of decenoic acid can be smoothly carried out.

[Function] The "residue discharged from the foreign royal jelly foreign matter removing operation performed in commercializing the raw royal jelly" is the following residue. That is, when commercializing the raw royal jelly, a foreign matter removing operation is first performed. In this operation, fresh royal jelly is filtered through a vibrating filter of about 60 mesh and the like, which is a viscous liquid residue remaining on the filter.
Such viscous liquid residue, together with solid matter such as pebbles and carcasses of bee larvae, together with 10-hydroxy-δ-2-decenoic acid and 10
-Hydroxydecanoic acid in amounts of about 20 to about 30% and about 6 to about 9%, respectively. Such a liquid residue is subjected to an extraction operation with a water-soluble organic solvent, and the contained 10-hydroxy-δ-2-decenoic acid is extracted with a recovery rate of almost 100%. As the water-soluble organic solvent used for extracting this residue, lower alcohols can be used, and among them, methanol and ethanol are preferable. In the extraction operation, a water-soluble organic solvent is added to the above-mentioned viscous liquid residue to separate the extract solutions by a centrifugal separation method, and such an operation is repeated several times, the extract solutions are combined and the solvent is distilled off.
Then, the obtained evaporation residue is dissolved in ether, and a crystallization operation in ether is repeated according to a conventional method to obtain crystals having a desired purity, followed by drying. During extraction with a water-soluble organic solvent, 10-hydroxydecanoic acid is also extracted into the residue of the raw material at the same time as the desired 10-hydroxy-δ-2-decenoic acid. This 10-hydroxydecanoic acid is 10-
Physical properties are very similar to hydroxy-δ-2-decenoic acid,
It is very difficult to separate and remove 10-hydroxydecanoic acid. However, according to the invention, 10-hydroxy-δ-2-decenoic acid can be isolated as crystals by crystallizing the extraction residue using ether. This is because the difference in the crystallization rate of both components in the ether solution was used. Thus, according to the present invention, the final 10-
Hydroxy-δ-2-decenoic acid is obtained.

EXAMPLES Some preferred specific examples of the production method according to the present invention will be illustrated below, but the present invention is not limited thereto. Example 1 The raw royal jelly residue stored frozen was thawed at room temperature, and then uniformly mixed with a homogenizer. 50.10 g of the obtained viscous liquid was subjected to extraction with methyl alcohol (100 ml each, 3 times). The three extracts were combined and the methyl alcohol was distilled off under reduced pressure. Ether was added to the residue to dissolve it, and the obtained ether solution was dehydrated with anhydrous sodium sulfate and then left standing at 25 ° C. in the dark for 24 hours for crystallization. The precipitated crystals were collected, dissolved again in ether and crystallized under the same conditions as described above, and then the crystallization operation was repeated several times. The melting point of the final product obtained was 63.5-65 ° C, and it was confirmed by NMR to be 10-hydroxy-δ-2-decenoic acid. The purity of the crystals obtained after each crystallization operation and the amount of coexisting decanoic acid were measured by gas chromatography.
