Abstract:

Asarum is a kind of commonly used traditional Chinese medicine, and volatile oil is the main material basis for its efficacy. In traditional studies, the volatile oil is extracted by steam distillation and analyzed by GC-MS. Although the extraction method is easy to operate and has low cost, it is time-consuming, large sample consumption, high extraction temperature and easy thermal decomposition of active components. Moreover, xylene is often added in this method to promote the stratification of volatile oil, which brings great interference to the subsequent GC-MS analysis and component identification of volatile oil. Therefore, Solid Phase Microextration (SPME) technology that integrates extraction, purification, enrichment, and sampling functions was used to analyze the volatile oil of Asarum for the first time. The HS-SPME/GC-MS method was established to analyze Asarum heterotropoides, and the volatile components were identified by the NIST spectral library search and retention index. A total of 68 components are identified from the volatile oil of Asarum heterotropoides from 6 origins. The relative content of methyl eugenol is the highest among the volatile components with peak area percentages ranging from 17.20% to 33.80%. The application of HS-SPME/GC-MS method to the study of the volatile components in Asarum heterotropoides can reflect the overall differences, and the method is simple and rapid, providing new ideas for the quality evaluation of Asarum heterotropoides.

Key words: Asarum heterotropoides, volatile components, HS-SPME/GC-MS
