A novel and rapid method for the spectrofluorometric determination of curcumin in curcumin spices and flavors

High Sensitivity Method for Determination of Trace Curcumin in the Aqueous Phase

“…It has been reported that curcumin has many pharmacological functions, such as antioxygenation, antibiosis and antitumor [1][2][3] . Methods such as high-performance thin-layer chromatographic (HPTLC) [4][5][6][7] , high-performance liquid chromatography (HPLC) [8][9][10][11] , capillary electrophoresis with amperometric detection (CE-AD) 12 , matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOFMS) 13 , spectrofluorimetry 14,15 , liquid phase tandem mass spectrometry (LC-MS/MS) 16,17 , 1 H NMR 17 , resonance light scattering technique (RLS) 18 and spectrophotometry [19][20][21] have been employed to determine curcumin in a variety of matrixes. However, most of these methods have low sensitivity, need a large number of organic solvents or metal ions.…”

Determination of curcumin in biologically active supplements and food spices using a mesofluidic platform with fluorescence detection

“…They are based on thin layer [5,6] and high performance liquid chromatography [7,8], ultra performance liquid chromatography-mass spectrometry [9], UV-VIS spectrometry [10][11][12] and spectrofluorimetry [13][14][15][16][17][18]. These methods are characterized by their high sensitivity, good reproducibility and recovery.…”

Fluorescence enhancement effect for the determination of curcumin with yttrium(III)—curcumin—sodium dodecyl benzene sulfonate system

“…Therefore, the investigation for the determination of CU is important for clinical medicine and pharmacology [1][2][3][4]. Methods such as thinlayer chromatography [5][6][7], high performance liquid chromatography [8][9][10][11], spectrofluorimetry [12][13][14][15] and UV-Vis spectrophotometry [16,17] have been applied to determine CU in a variety of matrices such as curcuma longa, food stuffs and biological materials. CU has extensive absorption around 424 nm and can emit the fluorescence around 495 nm in organic solvent, but they decrease strongly in aqueous solution.…”
