Public ISBD [article]  inThe journal of essential oil research > Vol. 17 N° 6 (Novembre-Décembre 2005) . - pp. 619-621 Titre : Composition of the essential oil from nuphar pumilum (Timm.) DC. growing in Russia Type de document : texte imprimé Auteurs : Mitsuo Myazawa, Auteur ; Jyunichi Kawata, Auteur ; Chikako Yamafuji, Auteur Année de publication : 2006 Article en page(s) : pp. 619-621 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Nuphar pumilum Nymphaceae Essential oil composition Cyclo-S8 Methyl palmitate linoleate Paeonol Chemotypes Résumé : The composition of the essential oils from rootstock of Nuphar pumilum has been investigated by capillary GC and GC/MS. In the case of the essential oils of N. pumilum, two chemotypes, Type A (Takasago Yakugyou) and Type B (Yamada Yakkyoku), were observed relative to their contents of elemental sulfur. Type A contained 51 components of which 16.1% were elemental sulfur (S6, S7, S8). The main components were cyclo-S8 (13.0%), methyl palmitate (10.1%), methyl linoleate (10.1%), paeonol (7.3%) and β-eudesmol (6.2%). Type B contained 77 components of which 0.6% was elemental sulfur (S8). The main components were paeonol (32.5%), eugenol (4.9%), menthol (3.6%), furfural (3.2%) and β-eudesmol (2.6%).

Essential oil and headspace constituents from the aerial parts of aster ageratoides turcz. var. ovatus nakai / Mitsuo Miyazawa in The journal of essential oil research, Vol. 20 N°1 (Janvier/Fevrier 2008)  

Public ISBD [article]  inThe journal of essential oil research > Vol. 20 N°1 (Janvier/Fevrier 2008) . - pp. 9-11 Titre : Essential oil and headspace constituents from the aerial parts of aster ageratoides turcz. var. ovatus nakai Type de document : texte imprimé Auteurs : Mitsuo Miyazawa, Auteur ; Jyunichi Kawata, Auteur ; Kanako Kohno, Auteur Année de publication : 2008 Article en page(s) : pp. 9-11 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Aster ageratoides var. ovatus Compositae Essential oil composition Headspace volatiles Bornyl acetate Résumé : The compositions of the essential oil from the aerial parts of Aster ageratoides var. ovatus (Compositae), have been investigated by GC and GC/MS. The volatile components were also isolated by headspace techniques and analyzed. As a result, the oil was revealed the presence of 106 components, representing 97.5% of the total oil. The main components of the oil were bornyl acetate (13.0%), terpinolene (9.7%), bicyclosesquiphellandrene (9.5%), (E)-β-ocimene (9.1%) and (Z)—β-ocimene (7.6%). Twenty-one components accounting for 99.6% of the headspace constituents were identified.

Identification of the key aroma compounds in dried roots of isatis tinctoria / Mitsuo Miyazawa in The journal of essential oil research, Vol. 18 N° 5 (Septembre-Octobre 2006)

The important odor-active compounds were also detected in the oil using GC-O and AEDA. As a result, the oil was revealed to contain 70 components, representing 97.4% of the total oil. The oil was composed of many nitrogen-containing components, such as 4-pentenonitrile (67.4%), benzenepropanenitrile (3.6%), 5-methyl hexanenitrile (3.5%) and 4-isothiocynato-1-butene (2.9%). AEDA and GC-O showed that 5-methyl hexanenitrile, skatole, benzenepropanenitrile, (E)-2-hexenal and menthol were the most aroma characteristic compounds of the oil.
