摘　　要：利用傅里叶变换红地光谱仪测试了草豆蔻、红豆蔻、云南草蔻、长柄山姜的红外光谱图，分析比较其图谱的差异，再结合原始红外光谱，根据各种化学键和官能团振动所引起的吸收峰形状和强度对山姜属植物所含的化学成分以及药理活性进行分析，由此进一步探讨山姜属植物的功效。结果表明，4种姜科植物的红外图谱峰形、峰位大体相似，化学物质大体相同，均有挥发油、强心苷、β-谷甾醇、二苯基庚烷、黄酮、鞣质、多糖、氨基酸等；但1600-1400、1300～l000cm^-1。范围的峰形、峰强差异明显，利用此波段的二阶导数进行相关性分析，得出云南草蔻与草豆蔻的相关系数最大、关系最近。By using the FTIR spectrometer on four species of Alpinia tested, A. galanga（ L. ） WiUd, A. blepharocalyx K. 5chum, A. kat- sumadae Hayata and A. kwangsiensls T. 1. Wu ＆ Senjen, analyses and compares the differenees of infrared spectrum, combined with the origi- nal infrared spectroscopy, according to the absorption peak shape and intensity caused by various chemical bonds and functional groups of vi- bration, to make analysis once chemical constituents of Alpinia and plants containing pharmacological activity. Four species of Alpinia IR peak shape, peak position similar, chemical substances are substantially the same, volatile oil, cardiac glycosides, β-sitosterol, diarylhep- tanoids, flavonoids, tannins, polysaccharide, amino acid, etc. But the 1 600 - 1 400, 1 300 - 1 000 cm^-1 peak shape, peak intensity differ- ence is obvious. Correlation analysis was performed by using second derivative infrared spectra in this range, the results of correlation coeffi-cient is obtained with the biggest is A. blepharocalyx K. Schum and A. katsumadae Hayata, closest.
