Carotenoids are naturally occurring compounds with wide ranging therapeutic potential especially their antioxidant, anti-inflammatory, antimicrobial, anticancer and neuro protective effects. Nevertheless, standard extraction methods involve the use of organic solvents toxic to the external and internal health. The aim of this study is to present the utilization of green technologies for obtaining and purifying carotenoids of natural origin, promoting the improvement of extraction efficiency and suppressing environmental impacts. Supercritical fluid extraction (SFE), microwave assisted extraction (MAE), and ultrasound assisted extraction (UAE) are discussed for their need of safer solvents (like water or ethanol combinations) and shortened extraction times and solvent consumption. The bioactivity of carotenoids is retained when using ecofriendly methods and the efficacy of carotenoids is evaluated for therapeutic applications using anticancer, antioxidant, anti-inflammatory, antimicrobial, and neuroprotective assays. This research underlines the possibility of green extraction technologies to facilitate a sustainable practice of carotenoid rich extracts being applicable to pharmaceutical as well as nutraceutical applications.
