The present invention relates to a method for simply and reliably regenerating silica gel used as an adsorbent in column chromatography. Column chromatography, which uses silica gel as an adsorbent, is a method for separating and purifying substances. When regenerating silica gel after developing and separating substances using this column chromatography, it is common to wash the silica gel with water or alcohol, and then sinter or heat dry it each time. This method has the disadvantage that the silica gel must be removed from the column. The present inventors investigated a method for easily regenerating a silica gel chromatograph, and found that when a solvent is used for development, washing is performed using a combination of certain solvents at a specific mixing ratio. It has been found that silica gel can be easily and sufficiently regenerated. Examples of substances to be subjected to development separation using silica gel column chromatography in the method of the present invention include isoprenoid-based high molecular weight oxygen-containing hydrocarbons such as vitamin K, solanesol, CoQ 10 and isodecaprenol. In general, in the development separation of this type of substance, the solvent is a solvent (hereinafter referred to as an eluent solvent) that has a greater elution capacity than the adsorption capacity of the substance to be separated on silica gel, or it is combined with the silica gel of the substance to be separated. Two types of solvents (hereinafter referred to as non-eluting solvents) having an elution capacity smaller than the adsorption capacity for It is usually 1 to 30% of the system. In this way, the silica gel used for development separation is contaminated with raw materials, intermediate products, by-products, small amounts of target products, etc. used in the production of isoprenoid-based high molecular weight oxygenated hydrocarbons. . The types of attached compounds vary depending on the type of raw material compound used, the type of isoprenoid-based high molecular weight oxygenated hydrocarbons to be produced, the form of the reaction, etc., but usually hydrocarbons, high-grade Alcohols, sterine, phospholipids, polymers, isoprenoid-based high molecular weight oxygenated hydrocarbons, etc. are attached. The silica gel with such compounds attached thereto is then washed according to the method of the present invention, with the eluent being added at 50-80% by volume based on the total solvent in order to reuse the solvent repeatedly. It is important to adjust the In this case, if the proportion occupied by the eluent solvent is larger than the above range, the subsequent replacement operation with the fixing solvent becomes extremely difficult. Moreover, if it is smaller than the above range, washing will not be carried out sufficiently and regeneration will not be possible. Conditions for washing can be appropriately selected depending on the type of substance to be separated. The combination of solvents used for regeneration according to the method of the present invention varies depending on the adsorption capacity of the specific substance to be separated on silica gel, but in general, eluent solvents include isopropyl ether, diethyl ether, ethyl acetate, acetone, Methanol and the like are selected, and non-eluting solvents also include hexane, cyclohexane, heptane, petroleum ether, benzene, kerosene, petroleum benzene and the like. Next, replacement is performed so that the washed silica gel can be used for the next development and separation. The solvent used for substitution is preferably the above-mentioned non-eluting solvent or the solvent used during development, and by this operation the silica gel is ready for use in a new operation. According to the method of the present invention, silica gel can be regenerated more than ten times without taking out the silica gel and performing any treatment such as heating. As described above, in the present invention, silica gel packed in a column can be easily regenerated with a small amount of solvent, and since the silica gel is sufficiently washed, it can be used more than 10 times. Furthermore, by using the same type of solvent for development as that used for regeneration, it is advantageous because the used solvent can be adjusted and reused. The present invention will be explained by the following examples, but the present invention is not limited thereto. In addition, all the mixing ratios of solvents in the examples are expressed in volume ratios. Example 1 100 g of silica gel is packed into a column along with benzene. 10.0 g of crude vitamin K 1 (purity 85%) is dissolved in 10 ml of benzene and this solution is allowed to flow down from the top of the column and is fixed. Next, purified vitamin K 1 with a purity of 95% is obtained by developing and separating with a mixed solvent of ethyl acetate/benzene (5:95) (recovery rate of 90%).
%). At this time, hydrocarbons such as isoprene, higher alcohols such as phytol and geraniol, and polymers such as phytol and geraniol dimers and triers are attached to the silica gel in the column, along with a small amount of crude vitamin K. Next, in order to reuse this column, without running out of the solvent in the column, it is washed with 500 ml of a mixed solvent of ethyl acetate/benzene (50:50), and then the solvent in the column is replaced with 500 ml of benzene. Next, the test results were shown in Table 1 when fixing, development and separation were carried out in the same manner as described above, and the test results were used repeatedly 20 times.

おりである。[Table] Furthermore, for comparison, the amount of solvent required for washing and substitution was compared when the same silica gel as above was regenerated in the same manner as in the conventional method. Conventional method (1) is the case where the silica gel is washed using the developing solvent as it is, and conventional method (2) is the case where the silica gel is washed with methanol and then replaced with benzene and then with the developing solvent. show. The amount of solvent used in the present invention is expressed as a quantitative ratio when the sum of the solvent used for washing (mixing ratio of ethyl acetate and benzene = 50:50) and the solvent used for substitution (benzene) is 1. Next, the results are shown in Table 3.

At this time, in addition to a small amount of crude phytol, sterine such as stigmasterol, phospholipid such as lecithin, and higher alcohol such as linalool are attached to the silica gel in the column. Next, washing is performed using 600 ml of a mixed solvent of ether/hexane (80:20), and then the solvent in the column is replaced using 900 ml of a mixed solvent of ether/hexane (5:95).
