Phytochemical composition of Hypericum genus has been investigated for many years. In the recent past, studies on the essential oils (EO) of this genus have been progressing and many of them have reported interesting biological activities. Variations in the EO composition of Hypericum species influenced by seasonal variation, geographic distribution, phenological cycle and type of the organ in.

  Introduction. Hypericaceae is a small cosmopolite dicot family represented by nine genera and about species of tree, shrub and herb in the world (Simpson, , APG III, , Carine and Christenhusz, ).Hypericum is the largest genus of Hypericaceae by comprising about species throughout the world except the poles, deserts and low altitude areas of tropical regions (Lewis, Objectives: Our previous studies had demonstrated cytotoxicity of Hypericum scabrum L. methanol extract against some tumor cell lines, suggesting the species for further studies. The objectives of the present study were to determine the most cytotoxic fraction of Hypericum scabrum L. and to assess the apoptosis induction ability of the most effective fraction as well as its methanol extract.

Main content area. Ethnopharmacology of Hypericum species in China: A comprehensive review on ethnobotany, phytochemistry and pharmacology. Saint-John’s-wort, genus of nearly species of herbs or low shrubs (family Hypericaceae) native to temperate and tropical areas. Common, or perforated, Saint-John’s-wort (Hypericum perforatum) is used in herbal medicine as a treatment for depression and is an aggressive invasive species in some areas.
