Method for producing microparticles from pressurized and heated starting material solution
The present invention addresses the problem of providing a method for efficiently producing uniform microparticles of curcumin and/or -oryzanol at a higher yield. The target microparticles are produced by dissolving a starting material in a solvent to give a starting material solution and then subjecting the starting material solution to crystallization by a poor solvent method to thereby deposit the starting material. To prepare the starting material solution, curcumin and/or -oryzanol are used as the starting material(s) and ethanol is used as the solvent. The starting material(s) and the solvent are stirred in a pressurized state at a temperature of 78.3-130 C. inclusive to give the starting material solution. Then, the starting material solution thus obtained is subjected to crystallization by the poor solvent method and thus the target microparticles are produced.

FE/CU-MEDIATED KETONE SYNTHESIS
Provided herein are methods for preparing ketone-containing organic molecules. The methods are based on novel iron/copper-mediated (Fe/Cu-mediated) coupling reactions. The Fe/Cu-mediated coupling reaction can be used in the preparation of complex molecules, such as halichondrins and analogs thereof. In particular, the Fe/Cu-mediated ketolization reactions described herein are useful in the preparation of intermediates en route to halichondrins.

Process for preparation of bioavailable white curcumin—a unique blend of hydrogenated curcuminoids
The present invention discloses a process for preparation of white curcumin from purified curcuminoids. The curcuminoids are obtained by solvent extraction and crystallization of dried turmeric powder. The autoclave is charged with ethyl acetate and the 95% purity curcuminoids mixture is added to and stirred for uniformity at room temperature. 5% (w/w) of 10% palladium carbon is added to the reaction mixture and allowed for hydrogenation in the presence of hydrogen gas at 2 lbps pressure and stirred continuously for 15 hours. Once the reaction is completed, the reaction mixture is filtered and washed with ethyl acetate. The ethyl acetate is distilled off and crude mass is stirred with water to obtain a solid precipitate. Finally, the solid obtained is filtered and dried to pale brown crystals of white curcumin. White curcumin is encapsulated with beta-cyclodextrin, which exhibited increased bioavailability. White curcumin also exhibited anti-oxidant and chemopreventive activities.
