摘要： In this study, the feasibility of single-walled carbon nanotubes (SWCNTs) as solid-phase extraction (SPE) adsorbent for the determination of bioactive crocin analogues in the traditional Chinese Medicine (TCM) of Gardenia Jasminoides Ellis prior to HPLC analysis was studied. Various experimental factors influencing SPE efficiency and HPLC conditions were studied. By using SWCNTs as the SPE adsorbent, the detection limit of 1.19-2.21 fmol (at S/N of 3) were achieved with the preconcentration efficiency of more than 120-folds, indicating this proposed method was very practical for increasing the sensitivity prior to HPLC analysis, and it may provides useful clue for the efficient extraction for the bioactive compounds in TCMs.
