Abstract
It is an object of the present invention to provide a novel means for purifying bisacurone from turmeric at low costs and in a high concentration. A method of producing a bisacurone-containing turmeric extract, comprising a stepwise extraction step of using a plurality of extraction solvents each having different polarity by combining them with one another in a predetermined order.
Claims9
A method of producing a bisacurone-containing turmeric extract, comprising:
- (1) a step of adding and mixing an aqueous solvent into turmeric, extracting a water-soluble component from the turmeric, followed by solid-liquid separation, and then recovering a solution comprising the water-soluble component;
- (2) a step of adding and mixing a hydrophobic organic solvent into the solution obtained in the step (1), and then separating and recovering a hydrophobic organic solvent phase;
- (3) a step of removing the hydrophobic organic solvent from the obtained hydrophobic organic solvent phase to obtain a dried solid matter;
- and
- (4) a step of adding and mixing an aqueous solvent into the obtained dried solid matter, followed by solid-liquid separation, and then recovering a solution.

A method of producing a bisacurone-containing turmeric extract, comprising:
- (1) a step of adding and mixing a mixed solvent of a hydrophilic organic solvent and water into turmeric, extracting a water-soluble component from the turmeric, followed by solid-liquid separation, and then recovering a solution comprising the water-soluble component;
- (2) a step of removing the solvent from the solution obtained in the step (1) to obtain a dried solid matter;
- and
- (3) a step of adding and mixing water into the obtained dried solid matter, followed by solid-liquid separation, and then recovering an aqueous solution.
