Titre : Analysis of the volatile constituents of five african and mediterranean hypericum L. (Clusiaceae, Hypericoideae) species Type de document : texte imprimé Auteurs : Sara L. Crockett, Auteur ; Betül Demirci, Auteur ; K. Hüsnü Can Başer, Auteur Année de publication : 2007 Article en page(s) : pp. 302-306 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Hypericum aegypticum ssp. aegypticum Hypericum aegypticum ssp. marrocanum Hypericum balearicum Hypericum delphicum Hypericum roeperanum St. John's Wort Clusiaceae Hypericoideae Essential oil composition β-caryophyllene Caryophyllene oxide γ-curcumene β-eudesmol Ishwarane α-pinene β-pinene Undecane Résumé : The volatile constituents of five species of the medicinally and ornamentally valuable genus Hypericum L. (St. John's Wort; Clusiaceae), with native distributions in Africa and the Mediterranean regions of Europe and Asia, were examined as part of our continuing research on the phytochemistry of Hypericum. The dried and ground aerial material of flowering plants was subjected to microdistillation to isolate volatile compounds, which were subsequently analyzed by GC/MS. The major constituent(s) of H. balearicum were α-pinene (28.5%), β-pinene (20.4%), and β-eudesmol (11.2%); of H. delphicum were caryophyllene oxide (31.5%), β-caryophyllene (18.2%), and undecane (17.5%); of H. roeperanum was γ-curcumene (15.6%); of H. aegypticum ssp. aegypticum was ishwarane (14.4%); and of H. aegypticum ssp. marrocanum were caryophyllene oxide (29.2%) and β-caryophyllene (15.1%). This paper represents the first report, to our knowledge, of volatile constituents for these species.

Bernh. was examined by GC and GC/MS. Oils hydrodistilled from samples collected from two different locations in Greece were found to possess minor compositional differences but considerable variation in the levels of some components.

Mots-clés : Pulicaria dysenterica Compositae Essential oil composition (Z)-nerolidol β-caryophyllene (E)-nerolidol Caryophyllene oxide Résumé : The chemical composition of the aerial parts oil of Pulicaria dysenterica (L.) Bernh. was examined by GC and GC/MS. Oils hydrodistilled from samples collected from two different locations in Greece were found to possess minor compositional differences but considerable variation in the levels of some components. Fifty-four components were identified representing 80.5% (sample A) and 72.6% (sample B) of the total oils. The main components in sample A were (Z)-nerolidol (11.2%), caryophyllene oxide (9.1%) and (E)-nerolidol (6.6%), while those of sample B were β-caryophyllene (12.8%), caryophyllene oxide (12.8%) and (E)-nerolidol (6.9%).

Philotheca cuticularis, both subspecies of P. difformis, P. glasshousiensis, P. myoporoides subsp. myoporoides, P. epilosa, P. obovata, P. queenslandica and P. sporadica all produced leaf oils in which the major component (<75%) was α-pinene. In P. acrolopha, the major components were α-pinene (34–42%) and β-caryophyllene (12–22%), while in P. ciliata the principal components were α-pinene (48–54%) and camphor (18–25%). In P. ericifolia the major components were α-pinene (16–25%), myrcene (7–10%), (E)-β-ocimene (18–34%) and the sesquiterpene spathulenol (13–21%). Pilotheca conduplicata produced a monoterpenic oil in which the main components were α-pinene (27.2%), limonene (43.8%) and (E)-β-ocimene (18.3%). In Philotheca papillata α-pinene (43.0%), camphene (9.3%) and elemol (8.8%) were the principal components of the leaf oil. The leaf oil of P. salsolifolia subsp. salsolifolia contained α-pinene (31.9%) and spathulenol (18.1%) as its major components, while in P. salsolifolia subsp. pedicellata sabinene (38%) and bicyclogermacrene (15.2%) were the major components.

The average moisture contents were 80.53% in leaves, 90.30% in rhizomes, 88.00% in pods and 14.19% in seeds when analyzed from fresh samples. The essential oils yield of leaves, rhizomes, pods and seeds were 0.46%, 0.69%, 0.83% and 4.30 % on a w/w dry basis, respectively. The pod and seed oil was analyzed by GC and GC/MS. Forty-two and 40 compounds from pods and seeds consisting of 95% and 99% of the total components were identified from the oils obtained. The major chemical constituents in pod oil were found to be γ-terpinene (27.1 %), β-pinene (15.4 %), α-phellandrene (8.5 %), 1,8-cineole (6.7 %) and p-cymene (6.4 %), while seed oil was predominated by 1,8-cineole (39.3 %) being followed by sabinene (10.4 %) and geraniol (6.8 %).

Twenty-two and thirteen components were identified in the oils from fresh and aged resins, comprising 95.8 % and 98.6 %, of the oils, respectively. The aged resin oil contained a high percentage of oxygen-containing sesquiterpenes (85.4 %) with a high predominance of β-(Z)-santalol acetate (83.1 %). In contrast, no sesquiterpenes were detected in the fresh resin oil and it was constituted basically by monoterpenes hydrocarbons (42.4 %) and oxygen-containing monoterpenes (27.7 %), of which α-phellandrene (13.9 %) and terpinen-4-ol (7.4 %) were the major components, respectively. The acaricidal activities against Tetranychus urticae of the resin oil were also investigated. Both oils showed fumigant toxicity (mortality and fecundity), but only the aged resin oil induced repellence.

Aspergillus flavus, Fusarium semitectum, Colletotrichum gloeosporioides and C. musae were most sensitive with growth inhibition of over 70%. The bioautography of the oil produced only one antifungal band representing 40% of the total oil. The fractionation of this band by reverse phase preparative HPLC (high performance liquid chromatography) yielded two peaks, in the proportion of 57.9% and 42.1%. The larger peak had only one compound, which was identified as ar-turmerone by MS (mass spectrometry) and NMR (nuclear magnetic resonance) spectra. The smaller peak contained two compounds, in the proportion of 31% and 69%, which were identified as β-turmer-one and ar-turmerone, respectively. Thus ar-turmerone constituted 87% of the fungitoxic component of the oil. The purified ar-turmerone showed antifungal activity similar to the crude oil.

From A. afra 37 compounds were identified, representing 95.3% (area percent) of the total oil and from L. ocymifolia var. raineriana, 27 compounds were identified, representing 91.1% of the total oil. Among the identified components camphor (46.2%), α-thujone (15.2%), artemisia ketone (7.4%) and 1,8-cineole (4.2%) were found as the main components of A. afra oil and germacrene D (36.8%), (Z)-β-ocimene (7.9%), β-caryophyllene (7.0%) and (E)-β-ocimene (4.4%) were the major components of L. ocymifolia oil. Furthermore, the oils, as well as nine of their constituents, were evaluated for their antimicrobial activity, against six bacteria, two oral pathogens and three pathogenic fungi. The results showed that the oil of A. afra has a moderate antimicrobial activity, while the oil of L. ocymifolia exhibited a stronger one against Gram-negative bacteria and oral pathogens, and a weaker one against Gram-positive bacteria. This interesting profle can be attributed to the high content of the oil, of germacrene D which is known for its antimicrobial activity.
