Objective The UHPLC-Q-Exactive-Orbitrap-MS was developed for the identification of chemical constituents in Xinmai'an. and an UHPLC-QTRAP-MS/MS method was also established for rapid and simultaneous determination of the content of 15 components in Xinmai'an. Methods ACQUITY UHPLC HSS T3 chromatography column (100 mm × 2.1 mm, 1.8 μm) was used with 0.1% formic acid (A)-acetonitrile (B) as the mobile phase in gradient elution．The data were collected by heated electrospray ion source (HESI) under positive and negative mode. Besides, Waters ACQUITY UPLC CSH C₁₈chromatography column (100 mm × 2.1 mm, 1.7 μm) was used with 0.1% formic acid water (A)-acetonitrile (B) as mobile phase for gradient elution. Multiple reaction monitoring (MRM) in positive and negative ion mode.by using electrospray ion source (ESI) was performed for quantitative analysis of 15 compounds in Xinmai'an. Results Based on the accurate mass measurements, mass fragmentation patterns combined with comparison of reference or literature reports, a total of 109 major compounds including 31 triterpenoids (mainly triterpene saponins), 25 flavonoids, 15 phenylpropanoids, 13 steroids, 9 monoterpenes, 7 quinones, and 9 other compounds were tentatively identified and speculated. Besides, under the optimized MS/MS condition, the linearity ranges of ginsenoside Re, ginsenoside Rg₁, ginsenoside Rb₁, ginsenoside Rb₂, ginsenoside Rc, ginsenoside Rd, danshensu, salvianolic acid B, tanshinone I, cryptotanshinone, tanshinone II_A, calycosin glucoside, astragaloside IV, paeoniflorin, albiflorin, ophiopogonin D, and ruscogenin were with good linearity (r ≥ 0.995 8). The average recovery rate of 15 compounds in the samples were in the range of 91.8%—106.5%, and the RSD range was from 1.9% to 4.5%. The RSD values of precision, stability and repeatability test were all less than 4.6%. Conclusion The results of this study clarified the chemical substance basis of Xinmai'an, and the method of UHPLC-QTRAP-MS/MS had good repeatability, high specificity, stability and controllability, which could be used for quality control of Xinmai'an.
