| Abstract
|
| [Objective] To analyze and compare the volatile compounds of Alismatis Rhizoma (AR) under different extraction methods,and to provide a basis for investigating the pharmacological activities of AR volatiles and for refining the evaluation of the medicinal quality of AR.[Methods] The volatiles of AR were extracted by steam distillation combined with headspace injection,and the volatile chemical constituents were qualitatively analyzed by GC-MS in two extraction regimes,respectively.[Results] The 56 chemical components were identified in the volatiles of AR by steam distillation,accounting for 36.89% of the total volatile components,mainly sesquiterpene alkenes,ketones and aldehydes,mainly guaiacolene (5.98%),γ-gurjunene (3.04%),α-amorphene (2.94%),etc. A total of 71 chemical components,accounting for 84.5% of the total volatile compounds,were identified in the volatiles of AR by headspace injection,mainly hexanal (38.39%),2-pentylfuran (6.91%),and α-amorphene (3.36%),among which aldehydes,heterocycles,and terpenes were predominant.[Conclusion] The species and relative contents of the volatile compounds of AR obtained by the two extraction methods differed,and a more comprehensive GC-MS information of the volatile compounds of AR can be established by combining the two methods. |
