This study was conducted in order to identify and compare essential oil compounds in different aerial parts of Artemisia sieberi. Plants sampled at random in full flowering stage in a CR （completely randomized） design with three replications. Analysis on leaves/stems revealed 55 identified compounds, representing 97.66% of the oil with a-pinene being the main component （34.33%）; other significant components in the leaves/stems include： α-amorphene, β-pinene, δ-cadinene, α-cadinene, methyl cyclopentan. For flowers/fruits （F/F） 29 compounds were identified, representing 96.96% of the oil with the main component being α-amorphene （15.86%） and α-pinene （12.34%） being the second main component. A number of other significant components found in fiowers/fruits were α-campholene aldehyde, isopinocarveol, β-caryophylene, calarene, δ-cadinene. Several compounds （some with significant compositions） were found in this variety ofA. sieberi which are not reported in the previous literature.展开更多
