Keay Brand new engrossed mountain deposits exercise an effective similarity with the obvious pitch products

The fresh new commonplace resin acid try dehydroabietic acid and you will oxidation of the-circumstances from abietic acid, and additionally eight-oxodehydroabietic and hydroxy- 7-oxodehydroabietic acids Contour 5.

Temperatures from the-factors particularly retene have been also noticeable. Methyl clermont foot 63 identification is within every examples and you may unmodified resin acids, abietic, pimaric and you can isoprimaric acids, was also noticed.

Much like the mountain trials, most of the three resin acids weren’t contained in every analysed products, age. The brand new lipid extractions given small amounts of fatty acids. Precisely the over loaded efas C and you will C were found in brand new products and you may were described as a heightened or equal amount away from C versus C Figures 5 and six.

This type of show concur that brand new amphorae lining was made from mountain plus the exposure of methyl dehydroabietate ways, as mentioned a lot more than, it was produced straight from new heat out-of timber Colombini mais aussi al

No plant otherwise animal sterols was in fact found in brand new examples. And also the visibility of one’s acids is not an indication out of certain contents of new amphorae, neither of your own adding from certain oils on their all-natural coatings. And additionally tartaric acidic, most other ingredients which might be within wines were in addition to within these samples: malic, malonic, fumaric, succinic acids Dining table dos. In these instances, although it can’t be definitively situated you to definitely drink are present in brand new vessels, they quality subsequent research.

To further consider should your blogs are wines, more sampling methods and perhaps most other strategies might possibly be looked at from inside the the long run. One another trials SN02 and SN07 have been regarding the excavation at Cadiz and you can samples have been obtained from the brand new ship necks.

Zero essential fatty acids other than C and you can C were understood. Syringic acidic and you will vanillic acidic was basically recognized in both products.

Syringic acid is recognized as being other biomarker of grape facts, based on malvidin malvidin- 3-glucosidethe commonplace anthocyanin the fresh pigment responsible for coloration off grapes Singleton, ; Guasch- of lipid removal of Keay Shape 6 – Partial overall ion chromatogram of your own lipid extraction regarding Keay Table 2 – Dominant substances observed in your wine biomarker extractions off Keay Furthermore, as Barnard mais aussi al.

Regarding trials clermont base 63 recognition, syringic acid are of the vanillic acidic and you can vanillin. This could recommend that in this case this isn’t relevant into the visibility off wine however, to help you something else. It is of interest to note one in the products on the necks out-of boats, including the a couple Keay In every cuatro neck trials, syringic acidic was recognized. Particularly, free syringic acidic is found in some plant provide, and in the small amounts inside lignin.

It is therefore possible that the fresh syringic acidic regarding trials arises from another provider particularly cork stoppers you to phorae. Two of the cuatro lipid extractions don’t imply detectable oily acids besides common non-symptomatic efas we. C and you may C with no plant or creature sterols was basically identified.

For instance the other amphora systems reviewed, the fresh new Keay Pinaceae points, such as for instance dehydroabietic acid, methyl dehydroabietate and you may 7-oxodeydroabietic acids, was also understood in examples, proving a slope lining. Each other examples contained extreme degrees of C Cholesterol levels and you will cholesterol oxidization affairs was in fact and additionally seen in both products. Cholesterol are an effective indicator off a pet source for the fresh new stuff. Definitive biomarkers regarding marine bacteria, such as for example isoprenoid efas, weren’t present in this new products away from either boats.

The new lipid analyses of your own examples shown pitch deposits acquiesced by the clear presence of dehydroabietic acid and you may seven-oxodehydroabietic omegle acidic

The clear presence of these essential fatty acids and cholesterol is the result either out of a pet stuff possibly seafood? In the wines biomarker extractions of the Keay Particular compounds you to are observed in wines, aside from tartaric acid, was in fact observed in the new products: malic, succinic and you will fuples Table 2.
