Abstract:
AIM To establish a GC method for the simultaneous determination of β-eudesmol,atractylon,atractylodin,atractylolide Ⅰ,atractylaxanthin Ⅱ and (4E,6E,12E)-tetradecene-8,10-diyne-1,3-diacetate in Atractylodes rhizome,and cluster analysis of A.rhizome according to the content level.METHODS The analysis of A.rhizome solution was performed on an HP-5 capillary column (30 m × 0.32 mm,0.25 μm) with FID as the detector,the initial temperature 100 ℃,with 10 ℃/min to 135 ℃;with 1 ℃/min to 150 ℃;with 50 ℃/min to 200 ℃ (keeping 6 minutes),and with 50 ℃/min to 250 ℃ (keeping 8 minutes).The FID detector temperature was 300 ℃ and the injector temperature was 250 ℃,with the flow rate carrier gas 1.4 L/min;The tail gas was N2 (99.999％),with the ratio of carrier gas Air ∶ H2 ∶ N2 =400 ∶ 30 ∶ 25;The sample volume was 1 μL,and the split ratio was 20 ∶ 1.The results were analyzed by cluster analysis with SPSS 21.0 statistical software.RESULTS Six constituents showed good linear relationships within their own ranges (r ＞ 0.999 6),whose average recoveries were 99.46％-100.95％ with the RSDs of 0.09-0.41.A.rhizome was divided into three categories.CONCLUSION This accurate,stable and reproducible method can be used for the quality control of A.rhizome.
