Résumé :	The compositions of the essential oil from Baphicacanthis Rhizome, dried roots of Isatis tinctoria (Cruciferae), have been investigated by capillary GC and GC/MS. The important odor-active compounds were also detected in the oil using GC-O and AEDA. As a result, the oil was revealed to contain 70 components, representing 97.4% of the total oil. The oil was composed of many nitrogen-containing components, such as 4-pentenonitrile (67.4%), benzenepropanenitrile (3.6%), 5-methyl hexanenitrile (3.5%) and 4-isothiocynato-1-butene (2.9%). AEDA and GC-O showed that 5-methyl hexanenitrile, skatole, benzenepropanenitrile, (E)-2-hexenal and menthol were the most aroma characteristic compounds of the oil.
