Abstract
Iridoids, a diverse class of plant food monoterpenoids, are characterized by a cyclopentane-fused pyran ring structure and exhibit extensive structural diversity and functional versatility. This review highlights recent advances in iridoid chemistry, biosynthesis via the methylerythritol phosphate pathway, and advanced extraction techniques such as ultrasound-assisted, microwave-assisted, and supercritical fluid extraction. Analytical methods such as liquid chromatography-mass spectrometry enable precise identification and quantification, advancing the study of their health-promoting properties. Iridoids demonstrate potent antioxidant, anti-inflammatory, neuroprotective, antitumor, antiviral, and hepatoprotective effects suggesting their potential use in functional foods, nutraceuticals, pharmaceuticals, and cosmetics. However, for the successful commercialization of iridoid-based products, future research should aim at the cost-effective production of iridoids using sustainable production systems, biotechnological synthesis, and clinical validation. This review reveals the significant promise of iridoids in enhancing human health through potential product innovation and assessment.
期刊介绍:
Food Chemistry: X, one of three Open Access companion journals to Food Chemistry, follows the same aims, scope, and peer-review process. It focuses on papers advancing food and biochemistry or analytical methods, prioritizing research novelty. Manuscript evaluation considers novelty, scientific rigor, field advancement, and reader interest. Excluded are studies on food molecular sciences or disease cure/prevention. Topics include food component chemistry, bioactives, processing effects, additives, contaminants, and analytical methods. The journal welcome Analytical Papers addressing food microbiology, sensory aspects, and more, emphasizing new methods with robust validation and applicability to diverse foods or regions.
