In this study, the mature rhizomes of 12 germplasms of Curcuma longa and C. zedoaria from different origins cultivated in Fujian, Quanzhou, were used as experimental materials. The orthogonal design method was used to optimize the extraction of curcumin (CCM), demethoxycurcumin (DMC) and bisdemethoxycurcumin (BDMC), and the content of 3 curcuminoids and 16 mineral elements in different germplasms were compared. The extraction rate peaked with the following extraction process: 100% methanol as solvent, 1:5 (g·mL-1) solid-liquid ratio, and ultrasonic extraction for 2 min. The maximum absorption wavelengths for CCM, DMC and BDMC were 424, 418 and 414 nm, respectively. The linear equations for the 3 curcuminoids were Y=0.170 3X+0.024 3 (CCM), Y=0.173 8X+0.041 (DMC), and Y=0.140 6X+0.051 4 (BDMC). The content of CCM, DMC and BDMC in GY03 was 1.23%, 1.22% and 1.50%, respectively, and that of total curcumin was the highest, 3.95%; The content of total curcumin in GY01 was next, up to 3.82%. GY03 and GY01 can be promoted in cultivated land as excellent breeding material. Among the 16 mineral elements detected in 12 turmerics, the contents of Mg, Mn, Al, Fe, and Zn were relatively abundant.
