Biological Activity Evaluation Process of Natural Antioxidants

Dear Colleagues,

Natural antioxidants are well-known to be health-promoting supplements. According to many literature reviews, the biological activities of natural antioxidants have been evaluated by various models, which can be mainly classified into five types of assessment, including physiochemical characteristic assessment, in vitro assessment (experiments on cells or tissues that are created artificially outside of living organisms), ex vivo assessment (experiments on living tissues taken directly from a living organism), in vivo assessment (experiments on living organisms), and clinical assessment (experiments on humans). Different types of biological activity evaluation of natural antioxidants can explain different things, such as their structure–activity relationship and physiological effects on cells, tissues, and living organisms. Therefore, a critical process for biological activity evaluation is needed in order to precisely clarify the physiochemical properties and biological actions of natural antioxidants.

Based on this consideration, this Special Issue titled “Biological Activity Evaluation Process of Natural Antioxidants” aims to curate novel advances in the development and application of methods for the biological activity evaluation of natural antioxidants. Topics include but are not limited to:

• Development of new methods for the antioxidant activity evaluation of natural resources.
• Improvement of existing methods for the antioxidant activity evaluation of natural resources to increase the efficiency and precision of evaluation.
• Exploring new antioxidant actions of natural resources.
