Abstract

A method based on high-performance liquid chromatography (HPLC) with ultraviolet detection has been developed to quantify coenzyme Q10 (CoQ10) in raw materials and dietary supplements. Single-laboratory validation has been performed on the method to determine linearity, selectivity, accuracy, limits of quantification (LOQ) and repeatability for CoQ10. An excellent linearity (r=0.999) was observed for CoQ10 in the concentration range $15.625{\sim}500\;{\mu}g/ml$ in dietary supplement. Observed recovery of CoQ10 was found to be between 98.33 and 99.38%. LOQ was found to be $250\;{\mu}g/ml$ Repeatability precision for CoQ10 was between 0.15 and 0.21% relative standard deviation (RSD). Further, limited studies showed that some adulterants and degraded material could be satisfactorily separated from CoQ10 and identified.

코엔자임 Q10은 우리나라뿐 아니라 여러나라에서 각광받고 있는 건강기능식품 중 하나로 이에 대한 분석법을 마련하고 이에 대한 분석법 검증을 하고자하였다. 분석기기로는 HPLC를 사용하였으며 분석법 검증을 위하여 직선성, 선택성, LOD, LOQ, 정밀성, 정확성을 확인하였다. 또한 현재 유통 중인 개별인정형 건강기능식품의 코엔자임 Q10 함량을 모니터링 한 결과 모든 제품이 적합함을 알 수 있었다. 따라서 확립된 분석 방법은 신속하고 효과적으로 분석하는데 이용될 수 있을 것이며, 개별인정형제품의 코엔자임 Q10이 공전에 등재시 본 연구결과가 시험법으로 활용할 수 있을 것으로 사료된다.
