Abstract:

        We analyzed volatile components in fresh and dried leaves of Artemisia argyi Levl. et Vant. with headspace solid phase microextraction ( SPME) and GC-MS. We also investigated the impacts of different SPME fibers and extraction temperature on the extracts. Results demonstrate that 65 μm PDMS /DVB fibre and temperature of 60 ℃ exhibit good extraction effect．We employed peak area normalization method to determine the volatile components. Fifty-eight compounds are identified in the fresh and dried leaves of Artemisia argyi, which include alkanes，alkenes and alcohols，and whose area exceeds 90% of the total peak area. Results also show that fresh and dried leaves of Artemisia argyi not only contain identical volatile compounds such as Camphene, 1-Octen-3-ol, alpha Phellandrene, Benzene, 1-methyl-2 (1-methylethyl) Eucalyptol and Caryophyllene, but also contain their own unique volatile compounds. This shows that their volatile  components  change after dryness.
