摘要(Abstract):

目的建立一种芫荽茎叶中芳樟醇、癸醛、正癸醇和十一醛的GC含量测定方法。方法以挥发油提取器蒸馏制备供试液;HP-5MSI毛细管色谱柱(30 m×0.25 mm,0.25μm),以氮气为载气,FID检测器,采用程序升温,内标法测定(柠檬烯为内标物)含量。结果芳樟醇、癸醛、正癸醇和十一醛进样质量浓度分别在31.5~315.0 mg.L-1(r=0.999 6)、269.0~2 690.0 mg.L-1(r=0.999 7)、95.3~953.0 mg.L-1(r=0.999 6)、58.1~581.0 mg.L-1(r=0.999 7)内呈良好线性关系,平均回收率分别为102.0(RSD=1.5%)、102.0(RSD=0.6%)、101.9(RSD=1.1%)、102.6(RSD=0.9%)。结论所建立的方法可用于芫荽茎叶中4种挥发性成分含量测定。
Objective To establish a method for determining the contents of linalool,decanal,n-decanol,undecanal in Coriandrum sativum L.leaf.Methods The sample solution was distilled in vaporizing oil extraction apparatus.With HP-5MSI capillary column(30 m×0.25 mm,0.25 μm),nitrogen as the carrier gas,FID as the detector,the programmed temperature-GC and internal standard(Limonene was used for the internal standard)method were employed to determine the components.Results The results showed that the linear ranges of linalool,decanal,n-decanol and undecanal were 31.50-315.0 mg · L-1(r=0.999 6),269.0-2 690.0 mg · L-1(r=0.999 2),95.3-953.0 mg · L-1(r=0.999 8),58.1-581.0 mg · L-1(r=0.999 7).The average recovery of the method were 102.0%(RSD=1.5%),102.0%(RSD=0.6%),101.9%(RSD=1.1%),102.6%(RSD=0.9%).The average recovery of the method were 102.0(RSD=1.5%),102.0(RSD=0.6%),101.9(RSD=1.1%),102.6(RSD=0.9%).Conclusions The results show that this method is steady,accurate and practical which could be used for the determination of linalool,decanal,n-decanol and undecanal in Coriandrum sativum L.leaf.
