This study presents the phytochemical profile and in vitro and in vivo anticonvulsant and antioxidant activities of Epilobium hirsutum, which has been traditionally used in the treatment of epilepsy by local people of Turkey. In vitro studies revealed that the extract contained a pronounced amount of phenolics (206.3±0.9 mg Gallic acid Eq/g extract) and exhibited significant levels of antioxidant (FRAP; 6226 µmol Fe 2+ /g extract, ORAC; 6593 µmol Trolox Eq/g extract, DPPH; IC50:33.8 ug/mL and metal chelation; IC50:114 ug/mL) and anticonvulsant (AChE; IC50:71.2 ug/mL, BChE; IC50:92.5 ug/mL, GABA-T; IC50:94.7 ug/mL) activities. In vivo studies shown that the extract exhibited high anticonvulsant activities. In addition, the extracts regulated the behaviour, locomotion and mental activities of the mice tested. Biochemical evaluation of the brain tissue revealed that the extract inhibited the production of MDA and stimulated the increasing of antioxidant enzyme levels, which suggest the possible antioxidative role of the extract that worked as neuroprotective agents by scarfing the free radicals produced through PTZ seizure inducer and attenuate convulsions. Moreover the extract regulated serum biochemical parameters, total antioxidant, total oxidant, and ischemiamodified albumin levels. Chromatographic studies were revealed that gallic acid principally might be the major contributor of anticonvulsant and antioxidant activities with the additive contributions of fatty acids and mineral compounds. Findings obtained from this study partially justified the traditional use of Epilobium hirsutum in the treatment of epilepsy and suggest potential use of the extract as industrial or pharmaceutical agent.

Introduction In this study, patients before and after cardiac surgery with cardiopulmonary bypass (CPB) and control subjects were evaluated for erythrocyte glutathione peroxidase, catalase and superoxide dismutase enzyme activities, in addition to glutathione, malondialdehyde, serum total sialic acid, lipid-bound sialic acid, total antioxidant status, trace elements and mineral levels. The correlation of these variables with coronary artery disease (CAD) was also assessed. Methods A total of 30 CAD patients and 30 control subjects were included in the study. CAD patients were divided into three groups: before surgery (BS), first day after surgery (1 st day AS) and seventh day after surgery (7 th day AS). Results Malondialdehyde (MDA) and total sialic acid (TSA) levels were significantly higher in CAD (BS) than in the control group ( P <0.05, P <0.05). In addition, GSH and TAS levels were significantly lower in the 1st day AS group than in the control group ( P <0.001, P <0.01). Moreover, Co, Cu, Mg, Se, V and Zn levels were significantly lower in CAD (BS) group than in the control group ( P <0.01, P <0.01, P <0.01, P <0.01, P <0.05, P <0.001). Conclusions It was concluded that the levels of LDL-C, total cholesterol, triglycerides and CRP significantly associated with parameters, as well as Cu, Ca and SOD activity, should be measured together to monitor CAD. It is also considered that measuring TSA and MDA might be an appropriate choice for biomarkers of CAD.

In this study, antioxidant properties, trace element and mineral composition of Dactylorhiza umbrosa (Kar. & Kir.) Nevski (Orchidaceae) grown in the East Anatolia Region of Turkey was determined. The concentrations of trace element and mineral were determined by using inductive paired plasma-optical emission spectrometer (ICP-OES). It has founded that the quantities of important trace elements Mn, Cu, Co and Se were high and also the quantity of the Mg mineral was quite high. Dactylorhiza umbrosa (Kar. & Kir.) Nevski plant's element quantities were determined to be Sr > Mg > V > Mn > Li > Ti > Cu > Se > Cr > Pb > Co > As > Be > Zn > Cd respectively. Total antioxidant activity, total phenolic and flavonoid contents were 12.44 ± 0.20 mM ascorbic acid g-1 , 4.97 ± 0.48 mg gallic acid g-1 and 4.51 ± 0.29 mg quarcetin g-1 respectively in methanol extracts of Dactylorhiza umbrosa (Kar. & Kir.) Nevski plant. The presence of high levels of some trace elements, antioxidant activity, total phenolic and flavonoid contents in the methanol extract may have important to the showed antioxidant properties.
