摘　　要：目的:建立对我国独创的太空桔梗的非晶态有机物成分快速分析方法。方法:对第4代太空组、地面组和对照品桔梗从整体上进行测定和对比分析。结果:3组桔梗样品吸收峰的峰位和强度有一定程度的差异,表明太空桔梗中非晶态有机物成分及含量有所改变。太空组比地面组桔梗的活性成分(如皂苷,甾体,多糖类等)含量明显增多,特别是桔梗酸,脂肪油、脂肪酸及挥发油等含量高于对照品,同时木质素、氨基酸的含量也有所增加。结论:太空桔梗中多种活性成分的含量明显增加。该方法适于从整体上分析太空药材的非晶态有机物成分的变化。Objective：To establish a method for analyzing amorphous organic compound components of space Platycodon grandiflorum rapidly. Method： FTIR was applied for measuring and comparing P. grandiflorum of comparison group.the ground group and the 4th generation of space group. Result： Several active components （platycodin.polysaccharide etc. ） contents of space group are in- creased obviously. Conclusion：The major components and the structures remained inextenso ,and the effictive component contents are enhanced in the space P. grandiflorum. FTIR is a fast method to analyze the changes of amorphous organic compound components of the space traditional Chinese medicines.
