Hypericum species, growing wild in Anatolia, widely used in traditional medicine in Turkey. In order to determine the genotoxic effect of Hypericum heterophyllum, human lymphocytes were incubated with the aqueous extracts. The increasing extract concentrations of Hypericum heterophyllum induced micronucleus. The rise of micronucleus shows that Hypericum heterophyllum at high concentrations may ...
The responses of Hypericum perforatum root cultures to chitosan elicitation had been investigated through (1)H-NMR-based metabolomics associated with morpho-anatomical analyses. The root metabolome was influenced by two factors, i.e., time of culture (associated with biomass growth and related "overcrowding stress") and chitosan elicitation. ANOVA simultaneous component analysis (ASCA) modeling...
70 years have passed since the first isolation of the naphthodianthrones hypericin and pseudohypericin from Hypericum perforatum L. Today, they continue to be one of the most promising group of polyphenols, as they fascinate with their physical, chemical and important biological properties which derive from their unique chemical structure. Hypericins and their derivatives have been extensively ...
The aim of this study is to produce essential oil loaded nanofiber wound dressings from PVA, which a biodegradable and biocompatible polymer, by emulsion electrospinning method. Hypericum Perforatum oil, known for its antibacterial, antioxidant anti-inflammatory properties on skin disorders, was used Kolliphor RH40 surfactant added emulsify in polymer solution. In order examine the effect amoun...
