ABSTRACT
Objective To establish a UPLC-QQQ-MS/MS (ultra-high performance liquid chromatography triple quadrupole tandem mass Spectrometry) method for simultaneous detemination of 8 terpenoids compounds in Tripterygium wilfordii suspension cells. Methods The separation and analysis were performed on Water HSS T3 C18, with 0. 1% acetic acid solution-acetonitrile as the mobile phase for gradient elution. The column temperature was set at 30 ℃ with flow rate was 0.3 ml/min. The electrospray ionization (ESI) source was applied and operated in alternating positive and negative mode. Multi-reaction monitor (MRM) mode was used to quantify the 8 compounds. Results The limits of detection and limits of quantitation in 8 compounds (triptolide, triptonide, dehydroabietlc acid, triptophenolide, demethylzeylasteral, tripteridine, pristimerin, celastrol) were 0.0096-0.2480 ng and 0.0192-0.4960 ng, respectively. The correlation coefficents (r) of calibration curves were 0.9966-0.9993. The average recovery rates were 95.04%-105.20%, and the relative standard deviation was 2.14%-6.31%. Conclusions The established quantitative method is simple, rapid, sensitive and accuracy. It can be used for simultaneous analysis of 8 terpenoids compounds in Tripterygium wilfordii suspension cells by using UPLC-QQQ-MS/MS, which affords methodology evidence for research and quality control of Triptervgium wilfordii Hook. f. and its plant tissue cultures.
