Forty six and 43 compounds were identified for M. lasiocarpa and S. macrocarpa, respectively, representing 91.40% and 90.86% of their respective essential oils. Germacrene D （20.71%）,β-elemene （12.40%）, spathulenol （11.60%） and β-selinene （9.67%） were identified as the major compound of M. lasiocarpa. β-sesquiphellandrene （19.68%）, hexyl isobutyrate （12.65%） and octanal （9.53%） were found to be the major compounds ofS. macrocarpa. Essential oil composition ofM. lasiocarpa has been determined for the first time and the results have been discussed in view of chemotaxonomy, natural products and potential usefulness of these plants.展开更多
