The chemical composition of essential oils isolated by hydrodistillation of leaves of Coreopsis barteri Oliv. & Hiern and Coreopsis grandiflora Hogg ex Sweet were analysed by capillary GC and GC‐MS. Limonene (55.4%) and α‐phellandrene (12.9%) were found to be the major constituents of C. barteri oil whereas germacrene‐D (42.1%) and myrcene (11.7%) predominate in the volatile extract of C. grandiflora ; besides these two terpene hydrocarbons, the latter oil contains minor but significant amounts of two rather unusual compounds: 1‐phenyl‐1,3,5‐heptatriyne (5.2%) and precocene I (0.9%).
