Abstract Echinophora tenuifolia L. ssp. sibthorpiana (Guss.) Tutin, a member of the Umbelliferae family, is a typical aromatic plant of central Turkey. The hydrodistilled essential oil of aerial parts of the plant was analyzed by GC and GC/MS. Thirty-seven compounds representing 95.7% of the oil were established.
