Shajin is a Chinese “medicine” which has been used as an expectorant and tonic. Two steam distilled oils were obtained from the dried roots of Korean shajin (
Condonopsis lanceolata) and Chinese shajin (
Adenophora stricta). These oils had a medical and a green note, and were investigated by chromatographic and spectroscopic methods, respectively. A total of 70 compounds were identified from the neutral oils of Korean and Chinese shajin. The characteristic main constituents of Korean shajin were 2-acetylpyrrole, squalene, menthol and 5-methylfurfural, while those of Chinese shajin were paeonol, furfural, 2-acetylpyrrole and furfuryl alcohol. In addition, the acidic and phenolic fractions from Korean and Chinese shajin contained 16 and 3 compounds, and the main compounds were palmitic, linoleic acid and phenol, cresol, guaicol. Paeonol was isolated as the main compound from the phenolic fraction of Chinese shajin.
