Stachys byzantine, Lamiaceae family, has many biological properties. In this study, the free, esterified, and bound phenolic acids of Stachys byzantine were analyzed. The results indicated that the main phenolic acids in free extract were rosmarinic acid, para-coumaric acid, ferulic acid, and salicylic acid. The analysis of esterified extract revealed that para-coumaric acid, caffeic acid, gallic acid, ferulic acid, and salicylic acid were the main phenolic acids. Caffeic acid, salicylic acid, para-coumaric acid, ferulic acid and gallic acid were the main phenolic acids in bound extract. The sum of phenolic acids confirmed that, among the studied extracts, esterified extract had the highest amount of phenolic acids. So, it can be concluded that Stachys byzantine is a good source of esterified phenolic acids.
