The genus Hypericum L. comprises about 450 species which occur in all temperate parts of the world . In Iran, 19 species of 5 sections exist, two of which are endemic . The most commercially important member of this genus, H. perforatum L., is used as a valuable medicinal plant for nervous exhaustion, depression, and seasonal affective disorders . This genus contains a wide range of different natural product classes, including naphthodianthrones (e.g., hypericin), prenylated phloroglucinols (e.g., hyperforin), xanthones, flavonoids, biflavonoids, tannins, proanthocyanidins, and phenolic acids . Hypericum helianthemoides (Spach) Boiss., H. hirtellum (Spach) Boiss., H. scabrum L., and H. dogonbadanicum Assadi. are four Hypericum species whose oils have been subjected to analysis in this article.
