Abstract:Objective To study the diterpenoids from ethyl acetate extract of Euphorbiae Semen.Methods The medicinal was extracted by ethanol reflux, and the components in ethyl acetate extract were analyzed by ultra performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS) with reference samples. Sephadex LH-20 chromatography and silica gel column chromatography were employed for separation. Furthermore, the structure of compound 12 was confirmed by nuclear magnetic resonance (NMR).Results Twelve diterpenoids were identified from ethyl acetate extract of Euphorbiae Semen as euphorbia factor (EF) L25 (1), EFL1 (2), EFL13 (3), EFL7b (4), EFL12/EFL12 isomer (5), EFL18 (6), EFL17 (7), EFL3 (8), EFL7a (9), EFL23 (10), EFL11 (11), and EFL2 (12), respectively.Conclusion Combination of UPLC-MS/MS and traditional purification is a powerful means for investigating the chemical ingredients of ethyl acetate extract of Euphorbiae Semen.
Keywords:Euphorbiae Semen  UPLC-MS/MS  isolation  diterpenoids
