- Abstract
The essential oils were extracted from the fresh and dried roots of Codonopsis cordifolioidea by steam distillation approaches, and sixty-three compounds were identified by GC-MS analysis. The main principles are linolic acid (21.9%), retene (11.4%), pentadecane (7.4%), methyl-9,12,15-octadecatrienoate (6.8%), and heneicosylcyclopentane (3.8%). The total oxygenated aromatic hydrocarbons reach to 8.8%. Some components such as 9,12,15-octadecatrienoic acid methyl ester in the essential oils of dried roots vary greatly compared to fresh materials. According to the different relative contents, the possible diagnostic molecular markers for the characteristic odor were pointed out. The antimicrobial activity of the both essential oils was evaluated against eight microbial strains using agar dilution method. The results showed that only Staphylococcus aureus, Salmonella typhimurium, and Shigella flexneri were sensitive to the essential oils.
