| titleOfInvention | Process for preparing high purity pheophytin, Chlorin e6, and Chlorin e6 and PVP complex from natural products containing chlorophyll |
| abstract | According to an embodiment of the present invention, in the method for producing pheophytin, green plants or microalgae containing chlorophyll are dissolved in an extraction solvent composed of any one of methanol, ethanol, acetone or their respective aqueous solutions. Adding acid and stirring to extract the pheophytin extract; Filtering the mixture by adding hexane and water to a pheophytin extract; Adding carbon black to the filtered solution, stirring and storing the mixture for a predetermined time; Separating the hexane layer from the result of performing the storage step to obtain pheophytin (pheophytin); Disclosed is a method for producing pheophytin comprising a (pheophytin). |
