Qualité aromatique de la framboise (Rubus idaeus L.) II. Interprétation de l'indice d'arôme

1982

International audience; La mesure de l'indice d'Arôme, basée sur l'intensité de la coloration bleue qui se développe dans les distillats de framboises aromatiques traités par la vanilline en solution sulfurique concentrée, est interprétée en identifiant les principaux composés participant à cette réaction colorée. Six composés : géraniol, linalol, nérol, α-terpinéol, α- et β-ionones, ont été séparés, révélés et inolés par chromatographie sur couche mince de gel de silice (CCM) et identifiés par couplage chromatographie en phase gazeuse (CPG) et spectrométrie de masse (SM). Ces composés représentent près de 80% de la valeur de l'Indice d'Arôme d'un distillat d'une variété aromatique : Mallin…

Hydrocarbon chemotypes of some blackcurrant cultivars (Ribes sp)

1989

The hydrocarbon fractions of the essential oils of 11 cultivars of blackcurrant (Ribes spp) buds originating from collections in France and Australia have been submitted to GC/MS analysis. The major monoterpene and sesquiterpene hydrocarbons define chemotypes which have been conventionally described by a letter-based formula. Whereas four monoterpene chemotypes previously reported are confirmed, eight sesquiterpene chemotypes have to be redefined. They involve: δ-elemene, β-caryophyllene, γ-elemene, α-humuiene, alloaromadrene, germacrene D, γ-cadinene, and two unknowns. The different cultivars examined and their corresponding chemotypic formulae have been discriminated by principal componen…
