ANTIOXIDANTS: AN OVERVIEW ON THE NATURAL AND SYNTHETIC TYPES

An Overview on Two Valuable Natural and Bioactive Compounds, Thymol and Carvacrol, in Medicinal Plants

Thymol (2-isopropyl-5-methylphenol), and carvacrol (5-isopropyl-2-methylphenol) are the main components of the essential oils of some Laminaceae,Verbenaceae and Ranunculaceae members such as oregano, thyme, savory, etc. The formation of thymol and carvacrol is thought to involve hydroxylation of γ-terpinene and p-cymene precursors. They are produced by the plant species as a chemical defe...

The Effect of Natural and Synthetic Antioxidants on the Oxidative Stability of Biodiesel

Advantages and Disadvantages of Natural Antioxidants in Comparison with Synthetic Antioxidants

An Overview on Medicinal Chemistry of Synthetic and Natural Derivatives of Cannabidiol

Cannabidiol (CBD) has been traditionally used in Cannabis-based preparation, however historically, it has received far less interest as a single drug than the other components of Cannabis. Currently, CBD generates considerable interest due to its beneficial neuroprotective, antiepileptic, anxiolytic, antipsychotic, and anti-inflammatory properties. Therefore, the CBD scaffold becomes of increas...
