The ower and leaf oil of Hypericum triquetrifolium Turra (Guttiferae, Hypericoideae) from Calabria (Italy) were studied by GC and GC–MS. The major components identied in each oil were n ‐nonane (8%, 15%), β ‐pinene (8%, 4%), α ‐pinene (13%, 10%), myrcene (16%, 5%), β ‐caryophyllene (5%, 11%), germacrene‐D (10%, 13%), sabinene (13%, 3%) and caryophyllene oxide (5%, 12%) in the leaf and ower oils, respectively. The aerial parts of the same plant were also analysed by SPME. The SPME analysis showed higher yields of undecane (14%, 10%) and β ‐caryophyllene (14%, 10%) in comparison with the corresponding hydrodistillation oils, in addition to α ‐pinene, β ‐pinene, sabinene and myrcene, amounting to (9%, 6%), (7%, 4%), (1%, 9%), (1%, 10%) for the leaves and owers, respectively.
