Turkish Hypericum origanifolium Willd has been recently considered for its hypericin and phenolic content as a potential substitute of the well-established EU market position Hypericum perforatum. However, a complete phytochemical characterization of H. origamfolium has not carried out yet in order to assert its potential industrial value.The present paper represents the first attempt to define the aromatic fingerprint of a representative wild Turkish H. origanifolium Willd. population. In addition, its volatiles were studied as potential discriminating constituents between H. perforatum and H. origanifolium with a similar hypericin and phenolic composition.
