¹³C CPMAS NMR as an Alternative Method to Verify the Quality of Dietary Supplements Containing Curcumin.

ABSTRACT: Turmeric is a traditional Indian spice that has recently become very popular worldwide because it contains a powerful ingredient called curcumin, which has strong anti-inflammatory properties. Hence, dietary supplements containing extracts rich in curcumin have gained great popularity. The main problems related to curcumin-containing dietary supplements are poor water solubility and the fact that they are often faked by using synthetic curcumin instead of the plant extract. In this article, we propose the use of the ¹³C CPMAS NMR method to control the quality of dietary supplements. The analysis of ¹³C CPMAS NMR spectra supported by GIPAW computations allowed us to identify a polymorphic form present in dietary supplements (which affected the solubility of curcumin) a
