Standard calibration curves of six analytes showed satisfactory linearity (r2≥0.99 2) within the determined ranges. The lower limits of quantification were 0.5 ng/mL for paeoniflorin and liquiritin, 2.5 ng/mL for geniposide and saikosaponin b2 and 1.0 ng/mL for atractylenolide Ⅲ and paeonol, respectively. The intra-day and inter-day precision (RSD %) were all below 6.94 %, and the intra-day and inter-day accuracy (RE %) were within ± 6.10 %. The recovery and ME of six analytes were 85.99 %-98.10 % and 95.78%-108.06%, respecti
