ABSTRACT: Chrysin flavonoid has been presented as having numerous and promising bioactive effects, such as antioxidant, anticonvulsant, antihypertensive, anti-inflammatory, antineoplastic, antihyperlipidemic, and antidepressant. However, one of the main challenges for advances in studies on the bioactivity of chrysin is its low bioavailability in humans. Thus, aiming to overcome this barrier, several studies have demonstrated the bioactive potential of capsules containing chrysin. The objective of this review was to present the main methodologies used for the encapsulation of chrysin, and its main biological effects demonstrated so far. Our intention is to offer ways to advancement of research in the area of flavonoid encapsulation. As for the encapsulation techniques, it was found that they are diverse, and the most recurrent encapsulating agents were PEG, PLGA polymers and their derivatives, in addition to other agents, such as PCL, albumin, lipids and chitosan.The bioactive effects of the capsules are also numerous, and anticarcinogenic effects are the most frequent, in addition to other effects such as antioxidant, antidiabetic, antimicrobial and neuroprotective. In conclusion, we verified a lack of use of green techniques for the encapsulation of chrysin, and the production of lipid-water emulsions and the dissolution of chrysin in ethanol seems to be alternatives in this regard. In addition, bioactive potential of these capsules can be evaluated in other experimental models, and should advance to clinical trials and application in food formulations.
