Abstract
The chemical composition of the essential oils obtained from the aerial parts of Stachys candida and S. chrysantha were analysed with GC and GC/MS. Forty-two constituents were identified from the
two oils and α-cadinol, manoyl oxide, caryophyllene oxide, epi-α-muurolol and (E)-caryophyllene were found to be the major components. Furthermore, the oils were
tested against six Gram (±) bacteria and it was found that one of them exhibited significant
antibacterial activity.
