The present document is directed to co-crystals of resveratrol and/or curcumin with piperazine and their use in medicine and/or as food and feed supplements.

A method of extracting nutrients from a plant includes the steps of: pulverizing a water soluble nutrient-based plant part of a first plant material of the plant so as to form a first pulverized plant part; pulverizing a lipid soluble nutrient-based plant part of a second plant material of the plant so as to form a second pulverized plant part; subjecting the first pulverized plant part to a distillation so as to obtain a distillate and a first residue that contains a water soluble nutrient; and immersing the second pulverized plant part in the distillate to form a first mixture followed by distillation of the first mixture, so as to obtain a second residue that contains a lipid soluble nutrient.

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.
