LID - 10.3390/foods12122296 [doi] LID - 2296 AB - Coenzyme Q10 (CoQ10) is a vitamin-like compound found naturally in plant- and animal-derived materials. This study aimed to determine the level of CoQ10 in some food by-products (oil press cakes) and waste (fish meat and chicken hearts) to recover this compound for further use as a dietary supplement. The analytical method involved ultrasonic extraction using 2-propanol, followed by high-performance liquid chromatography with diode array detection (HPLC-DAD). The HPLC-DAD method was validated in terms of linearity and measuring range, limits of detection (LOD) and quantification (LOQ), trueness, and precision. As a result, the calibration curve of CoQ10 was linear over the concentration range of 1-200 microg/mL, with an LOD of 22 microg/mL and an LOQ of 0.65 microg/mL. The CoQ10 content varied from not detected in the hempseed press cake and the fish meat to 84.80 microg/g in the pumpkin press cake and 383.25 microg/g in the lyophilized chicken hearts; very good recovery rates and relative standard deviations (RSDs) were obtained for the pumpkin press cake (100.9-116.0% with RSDs between 0.05-0.2%) and the chicken hearts (99.3-106.9% CH with RSDs between 0.5-0.7%), showing the analytical method's trueness and precision and thus its accuracy. In conclusion, a simple and reliable method for determining CoQ10 levels has been developed here.
