Public ISBD [article]  in The 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  Methyl  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%).
