Essential oil variability of satureja cuneifolia ten. growing wild in southern puglia (Italy) / Luca Tommasi in The journal of essential oil research, Vol. 20 n°4 (Juillet/Août 2008)

Qualitative and quantitative analyses of steam-distilled oil were performed by GC and GC/MS. Cluster analysis made it possible to identify four different chemotypes: linalool, borneol, α-pinene, and borneol/α-pinene. Principal Component Analysis (PCA) highlighted the relations existing between the compounds that constitute the essential oils. Moreover, spatial autocorrelation, evaluated in the space described by the principal components, was used to analyse the relationships between chemical polymorphism and certain large-scale environmental conditions proper to sampling sites. Specifically, the arrangement of values in relation to Yearly Rainfall (YR) was found not to be random: the findings showed that increased water availability in the soil causes an arise in the presence of the borneol chemotype. In contrast, reduced water availability is directly correlated with the presence of the linalool and α-pinene chemotypes.

Koch from different European countries were determined using capillary GC and GC/MS methods. The oils were obtained in yields of 0.11–1.80% from dried cut roots and 0.09% from leaves. A total of 48 components were identified, representing over 87% of the total yield of oil. Ten compounds not earlier reported: trans-p-mentha-2,8-dien-1-ol, iso-thujyl alcohol, p-mentha-1,5-dien-8-ol, bicyclo[3.2.0]heptan-3-ol, 2-methylene-6,6-dimethyl, trans-carveol, perillaldehyde, sabinyl acetate, perillyl alcohol, methyl ester of methylpentadecate acid, and methyl hexadecadienate acid. The principal components in the oils of L. officinale roots were β-phellandrene (0.1–48.9%), pentylcyclohexadiene (0–12.3%), trans-sabinyl acetate (0–12.1%), α-terpinyl acetate (0–26.1%), (Z)-3-butylidene phthalide (0.1–31.2%), and (Z)-ligustilide (0.2–70.9%). Phthalide isomers were predominant (73.2–82.6%) in the oils from Estonia, France, and Belgium. The roots oil of L. officinale from Scotland was rich in β-phellandrene (48.9%) and phenylacetaldehyde (17.2%). Maximum content of trans-sabinyl and α-terpinyl acetates (total 38.2%) was found in the oil from Holland. Estonian L. officinale root oil contained in high quantities (E)-ligustilide (52.4–70.9%) and pentylcyclohexadiene (12.3%). The L. officinale leaf oil cultivated in Estonia contained in high amounts α-terpinyl acetate (55.8%) and β-phellandrene (11.3%). The content of (Z)-ligustilide (17.0%) in the leaf oil was smaller compared with the root oil.

The roots oil of L. officinale from Scotland was rich in β-phellandrene (48.9%) and phenylacetaldehyde (17.2%). Maximum content of trans-sabinyl and α-terpinyl acetates (total 38.2%) was found in the oil from Holland. Estonian L. officinale root oil contained in high quantities (E)-ligustilide (52.4–70.9%) and pentylcyclohexadiene (12.3%). The L. officinale leaf oil cultivated in Estonia contained in high amounts α-terpinyl acetate (55.8%) and β-phellandrene (11.3%). The content of (Z)-ligustilide (17.0%) in the leaf oil was smaller compared with the root oil. ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2008.9700022

Analyses of the oils by GC-FID and GC/MS revealed that the major constituents of these oils were linalool (23.1%) and linalyl acetate (23.1%) in lavender, citronellal (23.8%) and geranial (11.6%) in lemon-balm, α-pinene (29.2%) in juniper berry, neral (36.2%) and geranial (41.9%) in lemon verbena, 1,8-cineole (24.4%) and camphor (17.1%) in rosemary, α-pinene (31.1%) and δ-3-carene (18.6%) in cypress oil. The antimicrobial activity of the essential oils was evaluated on survival and growth of some microorganisms potentially dangerous to the safety of foods (Escherichia coli, Staphylococcus aureus, Listeria innocua). The antimicrobial tests were carried out both in solid and in liquid media. E. coli was the most sensitive organism among the tested ones to the inhibition effect of the oils.
