Abstract
Background: Obesity is a global epidemic throughout the world. There is thus increasing interest in searching for natural bioactive compounds with anti-obesity effect. A number of marine compounds have been regarded as potential sources of bioactive compounds and are associated with an anti-obesity effect.
Objective: Marine-derived compounds with anti-obesity effect and their current applications, methods and indicators for the evaluation of anti-obesity activity are summarized in this review. in order to make contributions to the development of marine-derived functional food against obesity.
Results: In this review, an overview of marine-derived compounds with anti-obesity effect, including marine polysaccharides, marine lipid, marine peptides, marine carotenoids is intensively made with an emphasis on their efficacy and mechanism of action. Meanwhile, methods and indicators for the evaluation of anti-obesity activity are discussed. We summarize these methods into three categories: in vitro assay (including adsorption experiments and enzyme inhibitory assay), cell line study, animal experiments and clinical experiments. In addition, a brief introduction of the current applications of marine bioactive compounds with anti-obesity activity is discussed.
Conclusion: Marine environment is a rich source of both biological and chemical diversity. In the past decades, numerous novel compounds with anti-obesity activity have been obtained from marine organisms, and many of them have been applied to industrial production such as functional foods and pharmaceuticals. Further studies are needed to explore the above-mentioned facts.
Keywords: Anti-obesity, marine-derived, digestive enzyme, appetite, fat absorption, adipogenesis, thermogenesis, utilization.
