Abstract
The essential oils of Plectranthus incanus Link and Clinopodium umbrosum (M. Bieb.) Koch, which were produced from plants collected in N.W. Himalayan region of India, were examined by GC/MS. Fourteen constituents were identified in P. incanus oil of which cis-piperitone oxide (35.70%) and piperitenone oxide (45.01%) were most predominant. Although only nine constituents were identified in C. umbrosum oil, cis-piperitone oxide (63.05%) and piperitenone oxide (17.98%) were found as major constituents.Keywords
