[ 1 ] - Evaluation of Chemical Composition and In-vitro Biological Activities of Three Endemic Hypericum Species from Anatolia (H. thymbrifolium, H. spectabile and H. pseudolaeve)

In the present work we carried out a phytochemical and biological investigation on three endemic Hypericum species, i.e. Hypericum thymbrifolium, Hypericum spectabile and Hypericum pseudolaeve from Anatolia in order to discover new sources of natural compounds for the treatment of inflammatory and neurodegenerative disorders. HPLC-DAD analysis indicated that two naphthodianthrones (pseudohyperi...

[ 2 ] - Antioxidant, anti-acetylcholinesterase, anti-inflammatory and DNA protection activities of Glaucium grandiflorum var. grandiflorum.

In this study, the antioxidant, antiacetylcholinesterase, anti-inflammatory, and DNA protecting activities of the aerial parts of Glaucium grandiflorum var. grandiflorum were evaluated. It was found that the lyophilized methanolic extract exhibited an inhibitory capacity against FeCl3/ascorbic acid induced posphatidylcholine liposome oxidation (EC50 = 2.62  0.08 mg/mL), quenched HOCl (5.87  0...
