Investigation phytochemical components of sumac plant growing in Tunceli

Sumac is a plant belonging to Anacardieceae family. In this study, the sumac plant naturally grown in Tunceli was collected from 5 different provinces, washed and dried at room temperature and kept in the fridge until analysis. In sumac samples, pH, color, ash amount, total phenolic content, DPPH free radical scavenging capacity, metal chelating capacity, CUPRAC, reduction force, mineral matter content, organic acids as tartaric acid, malic acid and citric acid, phenolic compounds as gallic acid, vanillic acid, caffeic acid, routine, resveratrol, (-)- epicatechin and (+) - catechin hydrate contents were determined. In the study total phenolic content was found in the range of 1929±63 mg GAE kg-1-231±10 mg GAE kg-1. In all sumac samples, the highest TPC was found in the acidified methanol extract and the DPPH free radical scavenging capacity was found in the acidified acetonitrile extract. It was determined that all extracts of S5 sample metal chelating capacity was higher than the other samples but lower than the metal chelating capacity of EDTA. CUPRAC was detected with the highest concentration of 118.0±3.0 mg KAE kg-1 in the acidified methanol extract, with the lowest 10.2±0.6 mg KAE kg-1 in the acidified acetonitrile extract in S5 sample. It was found thst the reducing power of all samples were found to be lower than the reducing power of synthetic antioxidants, and the samples were found to be rich in mineral substances, the predominant organic acid is malic acid, and phenolic compound is gallic acid.
