Abstract

In this study, for the purpose of standardized quality control of a cold medicine, we simultaneous analyzed four main chemical components of a cold medicine: acetaminophen, caffeine, methyl paraben, and propyl paraben. The sample was subjected to quantitative analysis using high performance liquid chromatography (HPLC), after pretreatment of four components. The experiment was carried out by using Isocratic elution at wavelength of 270nm. Acetonitrile and water (H2O) were used as a mobile phase at a flow rate of 1.0mL/min in a commercial C18 reversed-phase column. A volume of 10uL cold medicine were injected into the column with column oven temperature at 35℃. As a result of the experiment, the values of Resolution were 4.983, 1.596, 5.519, and 1.678 respectively-well over Rs >1.5, which indicates that the separation of four components were efficient. In addition, value of symmetry factor of the components was 1.056, 1.069, 1.032, and 1.133 respectively, to show its symmetrical stability. The calibration curve of all four components exhibits good linearity with R2 >0.9995 to 0.9999. Furthermore, the limit of detection(LOD) were between 0.0118 to 1.5973 mg/mL, while the limit of quantification (LOQ) were between 0.0353 to 4.7919 ㎍/mL with the recovery rate of 79.6% ~ 120.5%. The results of this study showed an efficient quality evaluation of a simultaneous analysis method for cold medicine components.

본 연구는 감기약의 품질관리를 위한 기초자료서, HPLC를 이용하여 감기약의 4가지 주요 성분인 아세트아미노펜(Acetaminophen), 카페인(Caffeine), 메틸 파라벤(Methly paraben), 프로필 파라벤(Propyl paraben)을 동시 분석하였다. 시료는 4가지 성분을 전처리한 후, 액체크로마토그래피(HPLC)를 사용하여 정량분석 하였다. 감기약의 분석은 상업용 C18 칼럼과 이동상으로 아세토니트릴(Acetonitrile) 과 증류수(H2O)을 사용하였으며, 아이소그라틱 기법(Isocratic Elution)을 사용하였다. 검출기는 PDA 및 UV detector를 사용하였으며, 유속은 1.0mL/min, 주입부피는 10uL, 칼럼오븐의 온도는 35℃, 파장은 270nm에서 수행하였다. 실험 결과 Resolution의 값이 각각 4.983, 1.596, 5.519, 1.678으로 Rs >1.5 이상으로 나타나 분리능이 우수하고 Symmetry factor 값은 1.056, 1.069, 1.032, 1.133으로 안정적인 대칭을 갖는 것을 알 수 있었다. 모든 표준성분의 검량선 값은 R2 > 0.9995 ~ 0.9999로 나타나 우수한 직선성을 나타내었다. 또한 검출한계(Llimit of detection) 와 정량한계(Limit of quantification)는 각각 0.0118 ~ 1.5973mg/mL 및 0.0353 ~ 4.7919㎍/mL, 회수율은 79.6% ~ 120.5%로 안정적인 값을 얻었다. 본 연구 결과는 실험적으로 입증한 감기약 성분의 동시 분석법에 의한 품질평가가 효율적임을 보여주었다
