This thesis examines the phytochemical composition and bioactive properties of red dragon fruit (Hylocereus costaricensis) aqueous extract, highlighting its antioxidant, anti-inflammatory, and anti-hyperglycemic potential. The extract, rich in phenols, flavonoids, and vitamin C, demonstrated strong antioxidant activity, reduced oxidative stress, and exhibited dose-dependent anti-inflammatory and blood sugar-regulating effects in vitro and in vivo. These findings support the fruit's potential as a functional food for preventing chronic diseases like diabetes and cardiovascular conditions, with further research needed for therapeutic validation.
