To evaluate the sulfur-fumigation effects on the chemical constituents of Chuanxiong Rhizoma.Alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Chuanxiong Rhizoma samples were analyzed by FIIR. FTIR spectra were acquired and disposed by software Omnic 8. 0, second derivative IR spectra were analyzed by software OPUS 6. 5 through smoothing and differentiation treatment to FTIR spectra, and the absorption frequencies of alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Chuanxiong Rhizoma samples were assessed by using principal component analysis with software SPSS.There were significant differences between sun-dried and sulfur-fumigated Chuanxiong Rhizoma samples in the region ranging from 2 000 cm-1 to 750 cm-1. Some absorption peaks weakened or disappeared, and some newly emerged after the processing of sulfur-fumigation.The processing of sulfur-fumigation can influence the effective constituents of Chuanxiong Rhizoma. The established method of FTIR combined with second derivative and principal component analysis has been proved to be an effective, intuitional and rapid approach to distinguish sun-dried and sulfur-fumigated Chuanxiong Rhizoma. |
