Antioxidant properties in vitro and total phenolic contents in methanol extracts from medicinal plants

In order to find out new sources of safe and inexpensive antioxidants, the antioxidant capacities of 45 selected medicinal plants were evaluated using ferric reducing antioxidant power (FRAP) and Trolox equivalent antioxidant capacity (TEAC) assays, respectively, and the total phenolic contents of these plants were measured by the Folin–Ciocalteu method. Most of these plants were analyzed for the first time for their antioxidant activities. It...
