Chemical composition of grape canes
چکیده انگلیسی

In this study, chemical composition of canes which were sampled from ten different grape cultivars was investigated. For the determination of total phenolics, total flavanols and total flavonol contents, canes were analyzed spectrophotometrically. The phenolic compositions of the canes, including caffeic acid, catechin, p-coumaric acid, epicatechin, gallic acid, luteolin and trans-resveratrol were detected by HPLC. The anthron method was used for the determination of total carbohydrate content. The minerals such as K, P, Ca, Fe, Mg and Zn were determined by ICP-OES. All the parameters investigated in this study significantly changed depending on the cultivar. The results showed that grape canes as agricultural wastes from commercial viticultural activities represent a potentially important source of phenolics, minerals, carbohydrates and proteins. Therefore the grape canes may be used as an easily accessible source of natural antioxidants and food supplement.


► In this study, chemical composition of canes was investigated.
► All the phenolics were determined by spectrophotometer.
► Total carbohydrate was determined by anthron method; minerals were determined by ICP.
► All the parameters changed depending on the cultivar.
► Canes have a major source of these compounds and may be used as natural antioxidants.
