Method for any one of the 1-3 Claims Which defines the characteristics in that this raw material is crude fat oil that It is obtained from the production of salad oil from rice from the brand of rice. 7. Procedures according to one of the 1-6 claims It characterizes that the alkali used in the hydrolysis process is selected from the sodium hydroxide group. Potassium hydroxide, LioH RnOH Na2CO2 K2CO3 NaHCO3 and mixtures of them 8.Method of claiming 1-7, any one It characterizes that the alkali used in the hydrolysis process is selected from the sodium hydroxide group. Potassium hydroxide and mixtures of these substances. 9. Method for one of the 1-8 Claims It defines the characteristics that the hydrolysis is performed by dissolving the raw material in an alcohol-solvent 1 0. Method according to claim 9, which characterizes that the solvent al This gohol is a constituent of at least a compound selected from a group of compounds represented by the chemical formula. Given below: CH3-OH, C2H5-OH, CH3 (formula) CH-OH, CH3 CH3 CH3CH2CH2-OH, CH3-C-OH, CH3 CH3CH2CH2CH2-OH 1 1. Methods according to the 2-10 claims. Any one Which determines the characteristics in the area where the ferulic acid is dissolved Separated by filtration, the temperature is 90 ํ to 100 ํ. 1 2. Method of claim 1-11, any one The characteristics were determined by the following steps: - Using the waste oil obtained from the production of fatty acids in rice from the rice brand as raw materials. And isopropyl alcohol Into this waste oil. - To heat the mixture while stirring the mixture. Then cool the hot mixture. - pouring hexane into the reaction mixture. In order to organize the dissolved material in the hexane - add dilute sulfuric acid to the persistent aqueous solution after removing the hexane dissolved material to make the aqueous solution. That said, it is acidic and therefore causes ferrulic acid precipitation - filtration of aqueous solution containing the precipitated ferulic acid. To get ferulic acid - dissolving ferulic acid back into hot water. And then cooled to make the contents of the pattern come out Crystallize to pure trans-ferrulic acid 1 3. Method of claim 1-11. The characteristics were determined by the following steps: - Use of waste oil obtained from fatty acid production in rice from rice bran as raw material. - Mixture preparation by adding potassium hydroxide. And Iho propyl alcohol - To heat this mixture while stirring the mixture and then cooling the hot mixture - pouring hexane into the reaction mixture. To remove the dissolved material in the hexane - add dilute sulfuric acid to the remaining aqueous solution after removing the hexane dissolved material to make the aqueous solution. It is acidic and therefore causes ferrulic acid precipitation - filtration of aqueous solutions containing the precipitated ferrulic acid. To obtain crude ferrulic acid; and - dissolve raw ferrulic acid into hot water. And then cooled so that the resulting solution was Crystallize to pure trans-ferulic acid 1 4. Method of claim 1-11. Which is characterized by the following steps. - Use of alkali oil blocks. Obtained from the production of fatty acids in rice from rice bran as raw materials. - Mixture preparation by adding potassium hydroxide. And Iho propyl alcohol Into this alkali lump - heating the mixture while stirring the mixture Then cool the hot mixture. - pouring hexane into the reaction mixture. To eliminate the dissolved material in this hexane - add dilute sulfuric acid to the persistent aqueous solution after removing the hexane dissolved material to make the aqueous solution. It is acidic and therefore causes ferrulic acid precipitation - filtration of aqueous solution containing precipitated ferrulic acid. To obtain raw ferrulic acid and - dissolving raw ferrulic acid into hot water And then cooled so that the resulting solution was Crystallize And therefore pure trans-ferrulic acid 1 5. Method of claim 1-11. The characteristics were determined by the following steps: - Using black oil obtained from fatty acid production in rice from rice bran as raw material. - Mixture preparation by adding potassium hydroxide. And ihopropyl alcohol into black oil - heating this mixture while stirring the mixture and then cooling the hot mixture - pouring hexane into the mixture. reaction To remove the dissolved material in the hexane - add dilute sulfuric acid to the remaining aqueous solution after removing the hexane dissolved material to make the aqueous solution. It is acidic and therefore causes ferrulic acid precipitation - filtration of aqueous solutions containing the precipitated ferrulic acid. To obtain raw ferrulic acid and - dissolving raw ferrulic acid into hot water And then cooled so that the resulting solution was Crystallize And therefore pure trans-ferrulic acid 1 6. Method of claim 1-11. The characteristics were determined by the following steps: - Using raw Y-orichanol with approximately 80% purity as raw material. - Mixture preparation by adding potassium hydroxide. And ihopropyl alcohol into raw y-orichanol - heating this mixture while stirring the mixture and then cooling the hot mixture - pouring hexane Into the reaction mixture To remove the dissolved material in the hexane - add dilute sulfuric acid to the remaining aqueous solution after removing the hexane dissolved material to make the aqueous solution. It is acidic and therefore causes ferrulic acid precipitation - filtration of aqueous solutions containing the precipitated ferrulic acid. To obtain raw ferrulic acid and - dissolving raw ferrulic acid into hot water And then cooled so that the resulting solution was Crystallize And therefore pure trans-ferulic acid
