The natural product content of the selected Cabernet Franc wine samples originating from Serbia: a case study of phenolics.

This work aimed to evaluate the content of selected phenolic natural products in the wine samples made of three new Serbian Cabernet Franc clones (Nos. 02, 010 and 012, respectively) and mother vine (used as the relevant standard) during the period 2008-2012. Compared with all other wine samples, the Cabernet Franc wine of the clone No.

Phenolic natural products of the wines obtained from three new Merlot clone candidates.

This work aimed to evaluate the total contents of polyphenolics (the Ribereau-Gayon-Maurié procedure), anthocyanins (using pH differential method) and tannins (the Nègre procedure) as well as the content of phenolic acids (using UPLC/MS chromatography), respectively of the wines obtained from three new Merlot clone candidates in the perennial clonal selection. The aforementioned chemical parameters were determined in the samples covering the period 2009-2012. In comparison both with the standard Merlot wine (mother vine) and the wines obtained from other two clone candidates, the Merlot wine of the clone candidate No.
