Abstract
Provided are a novel amorphous curcumin compound powdery composition that is inexpensive, is improved in bioabsorbability and bioavailability of curcumin, and has long-term stability, and a method for producing the powdery composition. The present invention relates to a powdery composition containing an amorphous curcumin compound and a hydrophilic modified starch and having a Raman spectrum including one or more peaks at wavenumbers of 1630, 1599, 1428, and 1243 (expressed in ±2 cm−1) and a method for producing the powdery composition.
Claims7
A powdery composition comprising an amorphous curcumin compound and a hydrophilic modified starch, wherein the powdery composition has a Raman spectrum including peaks at wavenumbers of 1630, 1599, 1428, and 1243 (express in ±2 cm−1) in accordance with FIG. 1 and an X-ray powder diffraction (XRPD) pattern in accordance with FIG. 2, wherein a weight ratio of the amorphous curcumin compound to the hydrophilic modified starch is 1:2 to 2:1.
