(Labiatae) were analyzed using GC and GC/MS. Thirteen components were identified in the oil of leaf with germacrene D (58%), α-pinene (10.4%) and bicyclogermacrene (4.4%) as main constituents. Ten compounds were identified in the oil of flowers with germacrene D (48%), α-pinene (19.7%) and β-selinene (10.1%) as main components. Ten compounds were characterized in the oil of stem with germacrene D (57%), α-pinene (8.6%) and 2-pentadecanone (6.5%) as main constituents. In the oil of root, germacrene D (35%), α-pinene (12.6%) and spathulenol (6.6%) were found as main constituents. All oils consist of monoterpenes, sesquiterpenes and aliphatic compounds.

The highest oleoresin per harvest occurred at January 2004 in the dry Amazonian season. The major volatiles of the oleoresin, α-copaene and δ-cadinene, changes from 36.4% to 51.2% and 13.7% to 17.3%, respectively. No appreciable changes were observed on the percentage of the volatile compounds during the seasonal observation, but the percentage of essential oils in the oleoresins also changes considerably (1.3% −21.3%). The amount of oleoresin harvested ranged from 0–100mL. In conclusion, for the specimen of C. martii studied, during the seasonal observation, oleoresin per harvested and the percentage of the essential oil changes considerably during seasonal observation, but the chemical composition were not affected. According our knowledge this is the first reported of the volatiles and seasonal observation from C. martii.

Gray) and its in vitro antimicrobial activity against thirteen strains of Paenibacillus larvae, causal agent of American foulbrood (AFB), was determined. This disease affects honey bees (Apis mellifera L.) colonies worldwide causing great economical loses. The antimicrobial activity of the essential oil was evaluated using the broth microdilution method. Seven compounds representing 93.1% of the total of this oil were identified in the headspace of the oil using SPME-GC/MS analysis. The main components were thymol (29.2%), p-cymene (23.3%), carvacrol (23.3%) and γ-terpinene (11.0%). One way ANOVA for minimum inhibitory concentration (MIC) data and minimal bactericide concentration (MBC) data, indicated highly significant differences between the P. larvae strains. Newman-Keuls test determined two homogeneous groups (α=0.05) corresponding to Argentinian and Italian strains with different responses to Andean thyme oil. The use of essential oils in the control of microbial strains allows an alternative scope for the control of this serious disease affecting honey and its by-products (wax, pollen and propolis). Such strategy can meet consumer demand for a diminution or absence of other antimicrobial chemical substances, which can be substituted by the addition of natural substances.

The volatile concentrates were examined by GC and GC/MS. A total of 111, 114 and 138 compounds were identified in the LLE, SDE and HS-SPME of the fruit, respectively. Limonene was the major component of these concentrates, followed by α-pinene. The relative proportions of the major compounds are shown to be dependent upon the isolation methods.

The end-products of monoterpene biosynthesis in April (vegetative stage) were trans-piperitone oxide and menthone in Chemotype I and II, respectively while in early September (flowering) there was an increase in precursory intermediates and their related biosynthetic products, i.e. limonene and piperitenone oxide in Chemotype I and pulegone, piperitenone and piperitone in Chemotype II. Differences in the percentage composition of the main oil constituents were observed between the oils from the different organs of plants in the same developmental stage and between the same organs in different developmental stages.

About 86–87% of total peak areas of chromatograms consist of monoterpenes and evaluating their composition in qualitative and quantitative manner they do not show significant differences with regard to varieties. Some increments of terpinen-4-ol, α—terpineol and α—terpinyl acetate was recognizable in the variety horizontalis, while the variety pyramidalis contained germacrene D and abietadiene to somewhat higher level. On the other side, a higher percentage of α—fenchene than that of camphene and the presence of a monoterpene hydrocarbon sylvestrene were found to bear some chemotaxonomic value for the taxon C. sempervirens.

About 86–87% of total peak areas of chromatograms consist of monoterpenes and evaluating their composition in qualitative and quantitative manner they do not show significant differences with regard to varieties. Some increments of terpinen-4-ol, α—terpineol and α—terpinyl acetate was recognizable in the variety horizontalis, while the variety pyramidalis contained germacrene D and abietadiene to somewhat higher level. On the other side, a higher percentage of α—fenchene than that of camphene and the presence of a monoterpene hydrocarbon sylvestrene were found to bear some chemotaxonomic value for the taxon C. sempervirens.

This study analyzed the essential oil variability in Thymbra capitata (L.) Cav. in specimens growing wild in 23 places in Southern Puglia (Italy). The results show high chemical polymorphism in the oil content of T. capitata. Application of the spatial autocorrelation index to the principal components highlighted a relationship between thermal parameters and the composition in terms of active principles. The carvacrol chemotype was only present under the hottest and driest conditions. These results show that not only is the biosynthetic pathway of phenolic monoterpenes in T. capitata favored in high-temperature environments, as reported in other Lamiaceae, but also that carvacrol is present only in markedly “Mediterranean-like” environments.

Results showed differences within harvesting sites and between the different sites of collection but did not revealed clear tendencies in the evolution of the oil composition with regard to the sampling period. The main group of compounds in all the analyzed samples were: α-pinene (11.9%-42.1%), β-pinene + sabinene (6.0%-39.8%) and β-phellandrene + 1,8-cineole (8.8%-27.4%) except in one oil where β-caryophyllene (23.4%) was the principal component. The insecticidal activity of H. spicigera and its principal terpenic components was evaluated against the cowpea weevil Callosobruchus maculatus F., the major cause of damages of cowpea (Vigna unguiculata (L.) Walp) in North Cameroon.

Results showed differences within harvesting sites and between the different sites of collection but did not revealed clear tendencies in the evolution of the oil composition with regard to the sampling period. The main group of compounds in all the analyzed samples were: α-pinene (11.9%-42.1%), β-pinene + sabinene (6.0%-39.8%) and β-phellandrene + 1,8-cineole (8.8%-27.4%) except in one oil where β-caryophyllene (23.4%) was the principal component. The insecticidal activity of H. spicigera and its principal terpenic components was evaluated against the cowpea weevil Callosobruchus maculatus F., the major cause of damages of cowpea (Vigna unguiculata (L.)
