Cirsium japonicum Extracts Show Antioxidant Activity and PC12 Cell Protection against Oxidative Stress

Antioxidant and antidiabetic activities of extracts from Cirsium japonicum roots

This study investigated the antioxidant activity of methanol (MeOH) and water extracts from roots of Cirsium japonicumin vitro. MeOH extract showed a stronger free radical scavenging activity than water extract. However, both of extracts showed a concentration dependent hydroxyl radical scavenging activity, reducing power and metal chelating ability. MeOH extract had greater phenolic and flavon...

Protection against Oxidative Stress

Neuroprotective activity of Leontice leontopetalum extract against H2O2-stimulated oxidative stress in PC12 cells

Background and objectives: Neuronal toxicity can be induced by oxidative stress via free radicals production. In recent years, great interest has been expressed to the traditional and herbal medicines. The purpose of this study was to elucidate the neuroprotective activity of Leontice leontopetalum methanol extract against H2O2-stimulated oxidative stress in PC12 cells...

Resveratrol-loaded Nanoparticles Induce Antioxidant Activity against Oxidative Stress.

Resveratrol acts as a free radical scavenger and a potent antioxidant in the inhibition of numerous reactive oxygen species (ROS). The function of resveratrol and resveratrol-loaded nanoparticles in protecting human lung cancer cells (A549) against hydrogen peroxide was investigated in this study. The 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay was performed to evaluate ...

Evaluation of Neuroprotective Effect of Althaea Officinalis Flower Aqueous and Methanolic Extracts against H2O2-Induced Oxidative Stress in PC12 Cells

Objective: This study was conducted to evaluate the possible antioxidant activity and neuroprotective effects of aqueous and methanolic extracts of Althaea officinalis flowers against H2O2-induced oxidative stress in PC12 cells. Material and Methods: The antioxidant potential of extracts was evaluated by radical scavenging activity using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. For c...
