To develop and validate an efficient method for extraction and analysis of artemisinin from the plant samples of Artemisia annua *** rapid resolution liquid chromatography triple quadrupole mass spectrometry(RRLC-QQQ).Following ultrasound-assisted extraction(USE),RRLC-QQQ was utilized to separate and determine artemisinin from the plant sample of Artemisia annua L..The LC separation,QQQ-MS detection and multiple reaction monitoring(MRM) mode were optimized,and the method validation concluding selectivity,calibration,accuracy and precision,and recovery were also *** separation was performed with an isocratic elutes of 20%of methanol/water(10 mmol/L ammonium acetate,pH 4.0) on a C *** triple quadrupole MS detection was carried out under MRM mode of precursor ion[M+H]→fragment ions m/z 265.1 and m/z *** and LOQ of artemisinin were 0.20 and 0.75 ng/mL,*** intra- and inter-day precision did not exceed 3.71%,and the deviation of the intra- and inter-day mean values did not exceed±7.50. The average recoveries for artemisinin ranged from 92.45 to 103.8%with RSD from 2.47 to 2.79%.
