Titre : Analysis of the volatile constituents of asian hypericum L. (Clusiaceae, Hyperidoideae) species Type de document : texte imprimé Auteurs : Betül Demirci, Auteur ; K. Hüsnü Can Baser, Auteur ; Sara L. Crockett, Auteur Année de publication : 2006 Article en page(s) : pp. 659-663 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Hypericum acmosepalum beanii calycinum choisyanum forrestii kouytchense lancasteri leschenaultii monogynum patulum pseudohenryi xmoserianum St. John's Wort Clusiaceae Essential oil composition δ -cadinene Caryophyllene oxide Cuparene Ar-curcumene Cis-eudesma-6,11-diene Eudesmadienone Cis-β -guiaene γ -muurolene Myrcene α -pinene β selinene α -terpineol Tricosane Résumé : Of the 57 species of the economically important genus Hypericum (St. John's Wort; Clusiaceae) occurring in China, only a small percentage have been previously phytochemically investigated. As part of our continuing research on the phytochemistry of Hypericum, the chemical compositions of volatiles isolated from 12 Chinese species were determined. Volatile constituents were isolated by microdistillation of dried and ground aerial material from flowering plants and subsequently analyzed by GC/MS. The major component(s) were identified as follows: ar-curcumene (12.6%) and β-selinene (16.3%) in H. acmosepalum; γ-muurolene (11.3%), β-selinene (16.3%) and caryophyllene oxide (18.7%) in H. beanii; α-terpineol (11.5%) and P-pinene (29.2%) in H. calycinum; cis-eudesma-6,11-diene (11.4%) in H. choisyanum; a-pinene (10.4%) and caryophyllene oxide (12.7%) in H. forrestii; cis-β-guiaene (10.7%) and γ-muurolene (12.4%) in H. kouytchense; β-selinene (11.4%) and eudesmadienone (10.8%) in H. lancasteri; cuparene (24.8%) and γ-muurolene (16.8%) in H. leschenaultii; tricosane (13.3%) and myrcene (10.4%) in H. monogynum; β-selinene (14.7%) in H. patulum; β-selinene (18.5%) in H. pseudohenryi; and γ-muurolene (10.7%) and δ-cadinene (10.2%) in H.

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. marrocanum balearicum delphicum 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.
