摘 要:采用傅里叶变换红外光谱的各种测定方法测定了植物中药材白术,通过白术木质部及外表皮部的水平衰减全反射傅里叶变换红外光谱(HATR-FTIR)吸收比较,表明了外表皮含有更多的白术内酯及其衍生物等物质。新鲜的白术木质部比干燥白术木质部含有更多的化学物质,这可能是样品干燥后挥发油减少之故。对白术木质部及其伪品的木质部的HATR-FTIR进行二阶导数转换,进行峰位一致率检验,结果差异极显著。The present paper used many kinds of mensuration of FTIR spectroscopy to determine traditional Chinese drugs-Rhizoma Atractylodis Macrocephalae. Comparing the horizontal attenuated total reflection-Fourier transform infrared spectra(HA- TR-FTIR) of xylem and outer layer parts of cuticle indicates that there are more butenolide and its derivatives in outer layer parts of cuticl~ Much more chemical materials could be found in fresh sample than in drying sample, possibly due to the decreased amount of naphtha in the drying sample. The HATR-FTIR of xylem of Rhizoma Atractylodis Macrocephalae and its confusable varieties were transformed into second derivative FTIR to make sure whether the peak location is consistent. As a result, the difference is significant.
