Short Overview of Some Assays for the Measurement of Antioxidant Activity of Natural Products and Their Relevance in Dermatology

Impaired systemic redox homeostasis is implicated in the onset and development of various diseases, including skin diseases. Therefore, continuous search for natural products with antiox-idant bioactivities applicable in biomedicine is attractive topic of general interest. Research ef-forts aiming to validate antioxidant potentials of natural products has led to the development of several assays based on various test principles. Hence, understanding the advantages and limita-tions of various assays is important for selection of assays useful to study antioxidant and relat-ed bioactivities of natural products of biomedical interest. This review paper gives a short over- view on some chemical and cellular bioassays used to estimate the antioxidant activity of chosen natural products together with a brief overview on the use of natural products with antioxidant activities as adjuvant medicinal remedies in dermatology.
