In the present study the qualitative and quantitative analysis of phenolic acids such as chlorogenic CA), caffeic (CFA), ferulic (FA), rosmarinic (RA) and p-coumaric acids (PCA), were performed by using high pressure liquid chromatography in the aerial part and the root extracts of Scorzonera tomentosa L. (Asteraceae) which were collected from five different regions of Anatolia. Chlorogenic acid was determined as major phenolic acid content of Scorzonera tomentosa. The calibration curve was established as Y=23.21X-21.83 (r2= 0.999) for chlorogenic acid and the highest concentration was determined in the root extract of Yozgat sample with 1360.090 ± 6.732 fig.
