RESUMEN
Object To study IR absorption spectra of the extracts from chicken bile possessed excellent anti inflammatory and anticancer activity so as to develop this valuable resource.Methods Bile samples from chickens and various animals were dried in the dark and subjected to IR analysis respectively. Results By comparison, significant difference was found between IR spectra of chicken bile and other animals' bile, but the IR spectra of various chicken bile showed very good consistency. Conclusion The IR spectra of chicken bile is independent of raising places, species, feeding fashion, sampling season and age of sampled chicken. It was suggested that the bile of various chicken contained same chemical composition and this result was confirmed by UV and TLC analysis.
