[IR absorption spectral characteristics of chicken bile].

It has been proved by medicinal practice that the extraction from chicken bile has excellent antiphlogistic and anti-tumour effects. Chicken bile and the biles of various animals were dried and after IR spectral analyses, different IR spectra can be obtained with the resulting powders. In comparison with IR spectra, the IR spectrum from chicken bile is significantly different with that of other animals; whereas there are very good consistency among the chicken biles from different origin samples. The analyses of chicken bile show the chemical composition of chicken bile is different from that of other animals and the biles of different chicken have essentially same chemical composition.
