Chemical investigations on some Hypericum species growing in Turkey-I

Abstract

The chemical composition of five taxa of the genus Hypericum L obtained from herbarium specimens has been investigated. Namely, R adenotrichum Spach (endemic), H. calycinum L., H. cerastoides (Spach) Robson, 11 montbretii Spach, and H. perforatum L. were subjected to microdistillation to isolate the volatile compounds, which were analyzed by GC/MS.
