The effect of cadmium compounds containing selenium in different oxidation states such as Se(IV), Se(VI), and Se(–II) on production characteristics, shoot water content and chlorophyll content in the leaves as well as Cd and Se accumulation in plant organs of Hypericum perforatum plants was investigated. Complexes with nicotinamide (nia) of the type Cd(NCX)2(nia)2 where X = Se or S as well as C...

Hypericum species are known to be used in traditional therapies. H. scabrum L. is one of the Hypericum species distributed in Turkey. In this study, we evaluated the effects of Hypericum scabrum essential oil inhalation on spatial memory in scopolamine-induced amnesic rats. The essential oil was characterized by GC-FID and GC-MS system. Male wistar rats were divided into 6 groups: control; scop...

Hypericum formosanum is a valuable herb in Taiwan. In this study, response surface methodology was employed to optimize the ultrasound-assisted extraction of flavonoids from Hypericum formosanum. A central composite design with three variables (ethanol concentration, extraction time, and extraction temperature) was applied. Experimental results were fitted to the second order polynomial model a...
