Objective To establish a method for the content determination of six caffeoylquinic acids components in Carum carvi L. through quantitative analysis of multi-components with single marker (QAMS). To verify the feasibility and applicability of the method in its quality control. Methods Take 0.5 g of C. carvi powder (through the third sieve), accurately add 20 mL of 70% methanol, and conduct ultrasonic treatment (250 W, frequency 53 kHz) for 30 min to prepare the test solution. Phenomenex GeminiR C 18 column (250 mm × 4.6 mm, 5 μm) was used, acetonitrile-0.1% formic acid aqueous solution was used as mobile phase, gradient elution, flow rate was 1.0 mL·min^-1, column temperature was 30 ℃, and detection wavelength was 330 nm. Conduct methodological studies on specificity, test article extraction conditions, detection wavelength selection, chromatographic conditions, linear relationship, precision, repeatability, stability, and sample addition recovery. With isochlorogenic acid A as the internal reference component, relative correction factors of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B and isochlorogenic acid C was established. Three different chromatographs and three chromatographic columns were used to investigate the relative correction factor and relative retention time durability. The external standard method and QAMS were used to simultaneously determine the mass fractions of six components in C. carvi samples, and the differences between the two determination results were compared. Results The specificity, extraction conditions, detection wavelength selection, chromatographic conditions, linear relationship, precision, repeatability, stability, and sample recovery of the established HPLC detection methods for the six components meet the requirements. The relative positive factors of isochlorogenic acid A and neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B and isochlorogenic acid C were 1.362, 1.257, 1.335, 1.470, and 1.134, respectively. Three different chromatographs and three chromatographic columns had no significant impact on the relative correction factor and relative retention time. There was no significant difference between the calculated values of six components in three batches of samples by the QAMS and the measured values of the external standard method. Conclusion The method established in the study is simple and stable, and can be used for the synchronous quality control of six components (isochlorogenic acid A, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B and isochlorogenic acid C) in C. carvi.
