Total Phenolic Content (TPC) determination of cold and hot water extracts of Echinophora platyloba DC. Medicinal plant collected from Maragheh (East Azarbaijan, Iran)

The aim of the present study was to investigate total phenolic content (TPC) of cold and hot water infusions (room temperature for ۲ h and ۹۰ ºC hot water for ۵ min) from aerial parts of four different samples of Echinophora platyloba medicinal plants (Apiaceae or Umbelliferae) collected from different sites of Maragheh County (Kamel Abad, Tazeh Kand, Ekis and Golshahr). Results indicated that, the phenolic content of hot infusions was ۳۸.۶۵۷ ± ۱.۵۵۷ milligram of Gallic Acid equivalent per gram Dry Weight (mg GAE/ gDW) to ۷۲.۳۰۷ ± ۲.۸۹۷ mg GAE/ gDW and TPC of cold infusions was ۴۲.۷۶۸ ± ۱.۱۷۴ mg GAE/ gDW to ۴۹.۵۸۵ ± ۰.۳۷۴ mg GAE/ gDW. This study showed that the TPC values of hot water extracts prepared from Khousharizeh medicinal herbs using the Folin-Ciocalteu method was significantly different. The difference among samples was greatest in hot water infusions of Kamel Abad (۷۲.۳۰۷ ± ۲.۸۹۷mg GAE/ gDW). The results of this study indicate the presence of phenolic compounds that may provide the scientific basis for the traditional use of Khousharizeh and may provide valuable knowledge for future scientific research.
