This review summarizes stability of curcumin in solutions, spectroscopy characteristics of curcumin (UV, IR, Raman, MS, and NMR), polymorphism forms, method of analysis in both of biological and nonbiological samples, and metabolite studies of curcumin. For analysis of curcumin and its related compounds in complex matrices, application of LC–MS/MS is recommended.
