Thermal alteration of organic matter in recent marine sediments. 1: Pigments
Sediment from Tanner Basin, the outer continental shelf off Southern California, was analyzed for photosynthetic pigments and their derivatives, namely carotenes and chlorins. Samples of the sediment were also exposed to raised temperatures (65, 100, 150 C) for various periods of time (1 week, 1 month, 2 months). Analysis of the heat-treated sediment revealed the presence of alpha-ionene and 2,6-dimethylnapthalene, thermal degradation products of Betacarotente. Chlorins were converted to nickel porphyrins of both DPEP and etio series. Possible mechanisms of these transformations are presented
Iso-geraniol (3,7-dimethyl-3,6-octadien-1-ol): A novel monoterpene in Vitis vinifera L. cv. Muscat Roy
Isogeraniol (3,7-Dimethyl-3,6-octadien-1-ol): Ein neues Monoterpen bei der Sorte Muscat Roy (Vitis vinifera L.)Der Monoterpengehalt im Most der Neuzüchtung Vitis vinifera L. cv. Muscat Roy und ihrer Elternsorten Muscat Frontignan und Dabuki wurde untersucht. Das Monoterpenprofil von Muscat Roy ist dem von Muscat Frontignan sehr ähnlich. Trotzdem enthält es wesentlich höhere Konzentrationen an Geraniol und α-Terpineol. Im Most von Muscat Roy wurde ein neuer Monoterpenalkohol, 3,7-Dimethyl-3,6-octadien-1-ol (Isogeraniol) identifiziert; im Most der Elternsorten ist jedoch kein Isogeraniol nachweisbar
