The fresh new common resin acid was dehydroabietic acid and you can oxidization by-facts out of abietic acidic, also seven-oxodehydroabietic and you can hydroxy- 7-oxodehydroabietic acids Figure 5.

Temperature from the-items particularly retene have been along with apparent. Methyl clermont legs 63 identification is actually present in all the trials and you will unmodified resin acids, abietic, pimaric and you may isoprimaric acids, was indeed plus noticed.

Similar to the pitch products, all around three resin acids weren’t within all of the silversingles kortingscode analysed trials, elizabeth. New lipid extractions offered small amounts of fatty acids. Precisely the soaked efas C and you may C have been observed in brand new examples and you will was described as an elevated otherwise equal amount away from C as compared to C Numbers 5 and you may six.

Such abilities concur that the amphorae lining was created out-of slope plus the presence out of methyl dehydroabietate implies, as previously mentioned more than, it absolutely was produced directly from brand new temperature out of timber Colombini ainsi que al

Zero bush otherwise animal sterols was basically observed in the fresh products. And presence of your acids is not indicative out-of particular contents of this new amphorae, neither of the incorporating out of certain fats on their all-natural coatings. In addition to tartaric acid, most other compounds which might be within drink was in fact and found in these types of samples: malic, malonic, fumaric, succinic acids Table dos. In these instances, although it cannot be definitively based you to definitely drink is present in the latest ships, it merit further analysis.

To help check whether your stuff are wines, additional testing steps and perhaps other measures is looked at into the the future. One another samples SN02 and you may SN07 had been on the excavation on Cadiz and you will trials was indeed extracted from new boat necks.

No fatty acids except that C and you may C was in fact understood. Syringic acidic and you will vanillic acid was in fact recognized in both examples.

Syringic acidic is recognized as being another biomarker of grape facts, produced by malvidin malvidin- 3-glucosidethe common anthocyanin the fresh new pigment responsible for color from red grapes Singleton, ; Guasch- of lipid extraction of Keay Profile 6 – Limited complete ion chromatogram of your lipid extraction out-of Keay Dining table 2 – Principal compounds observed in the wine biomarker extractions from Keay Furthermore, just like the Barnard mais aussi al.

In the trials clermont foot 63 identification, syringic acid try associated with vanillic acid and you will vanillin. This may suggest that in cases like this that isn’t relevant towards the presence out-of wines but so you’re able to another thing. It’s of interest to notice that into the products from the necks from ships, such as the a couple Keay In every 4 neck samples, syringic acid try identified. Particularly, totally free syringic acid is found in particular bush source, also from inside the small amounts in the lignin.

Therefore it is possible that this new syringic acid on the trials originates from some other source such cork stoppers one phorae. Two of the 4 lipid extractions did not suggest noticeable fatty acids other than common low-symptomatic essential fatty acids i. C and you can C with no plant otherwise animal sterols were understood.

For instance the almost every other amphora types analyzed, the latest Keay Pinaceae circumstances, including dehydroabietic acid, methyl dehydroabietate and you may 7-oxodeydroabietic acids, was basically plus recognized both in samples, appearing a slope liner. Both products contains tall amounts of C Cholesterol and you will cholesterol oxidization products have been and thought of both in samples. Cholesterol is actually a robust indication of an animal origin for the newest posts. Definitive biomarkers regarding marine organisms, eg isoprenoid efas, weren’t seen in this new examples out of both ships.

The brand new lipid analyses of the samples found pitch deposits acquiesced by the presence of dehydroabietic acidic and you can seven-oxodehydroabietic acid

The presence of such fatty acids and you will cholesterol levels will be the impact possibly away from a pet blogs perhaps fish? On the wine biomarker extractions of the Keay Particular substances that are located during the wine, other than tartaric acidic, was in fact observed in the newest products: malic, succinic and you may fuples Dining table dos.
