摘要(Abstract):

[Objective]To identify the chemical components in the volatile oils of FRUCTUS TSAOKO in Yunnan Province.[Methods]Volatile oils were extracted from FRUCTUS TSAOKO by steam distillation method.Volatile oils in FRUCTUS TSAOKO were analyzed and identified by GC-MS method.Relative percentage of each component was determined by normalization method.HP-5MS capillary column(0.25 mm×30 m,0.25μm)was adopted.The temperature of injection port was 250℃;column temperature was 40℃(kept for 2 min)→150℃(kept for 2 min),10℃/min,150→250℃(kept for 5 min),15℃/min.Split ratio was 10∶1;and flow rate was 1.0 mL/min.[Results]A total of 37 chemical components were isolated and identified.Among them,the main components were eucalyptol(14.58%),3,7-dimethyl-2,6-diene aldehyde(6.66%),α,α,4-3-methyl-3-cyclohexene-1-methanol(8.49%),α-pinene(5.65%),β-pinene(4.54%)and so on.[Conclusions]This method had good isolation effects and could be used for the quality evaluation of FRUCTUS TSAOKO.
