Bioactive compounds and total antioxidant capacity of cane residues from different grape varieties
BACKGROUND Every year, the viticulture activity generates considerable amounts of underused lignocellulosic residues as grape cane, which are generally composted or burned despite their potential value as a source of bioactive compounds. Determination of their phytochemical composition and total an...

BACKGROUND
Every year, the viticulture activity generates considerable amounts of underused lignocellulosic residues as grape cane, which are generally composted or burned despite their potential value as a source of bioactive compounds. Determination of their phytochemical composition and total antioxidant capacity (TAC) may be a useful way of exploiting different high‐added value applications.
RESULTS
Twenty‐one phenolic compounds (PC) and two carotenoids (Car) were quantified by high performance‐liquid chromatography‐diode array detection in eight grape varieties from different locations in Mendoza, Argentina. The maximum concentrations corresponded to the stilbene ϵ‐viniferin [10 552 μg g−1 dry weight (DW)], followed by the flavanols (+)‐catechin (3718 μg g−1 DW) and (−)‐epicatechin (2486 μg g−1 DW). In addition, lutein and β‐carotene were quantified at levels ranging between 350 and 2400 ng g−1 DW. The TAC of the extracts was assessed by oxygen radical absorbance capacity, 2,20‐azino‐bis‐3‐ethylbenzthiazoline‐6‐sulphonic acid and 1,1‐diphenyl‐2‐picrylhydrazyl assays, with a good correlation between TAC and total PC for each sample (r ≥ 0.82).
CONCLUSION
Samples of cv. Malbec, the most representative variety of Argentina's winemaking industry, presented high contents of PC, particularly ϵ‐viniferin, (+)‐catechin and (−)‐epicatechin. Quercetin‐3‐galactoside, OH‐tyrosol and Car were reported for the first time in grape canes of the eight varieties.
