✦ Synopsis

The constituents of the essential oil of Stachys glutinosa L. were investigated for the ®rst time. In a ®rst part, we studied a collective oil following a methodology which combined chromatographic techniques (CC, GC) with spectroscopic techniques (MS, 13 C-NMR). Sixty-four constituents (91% of the total composition) were identi®ed. The major compounds were terpinen-4-ol (13.1%), a-pinene (10.1%), a-terpineol (8.4%), b-phellandrene (6.8%) and g-terpinene (6.1%). In a second part, we investigated 53 oil samples obtained from individual plants collected widely in Corsica, by GC±RI and GC±MS. The essential oils of S. glutinosa displayed a wide infraspeci®c chemical variability.
