Bitter orange (Citrus aurantium L.), a member of the Rutaceae family, finds global utility in both the treatment of various ailments and its role as a rootstock for Citrus species in agriculture. Various parts of Citrus aurantium L. have been employed in traditional medicine due to their multifarious therapeutic potential. The blossom of this plant serves as a rich source of bioactive compounds, notably polyphenols, alkaloids, and terpenes. Additionally, it harbors substantial quantities of functional, nutritive, and biologically active compounds, which manifest their presence through antioxidant, antidiabetic, anticancer, antimicrobial, cardiovascular, and neuroprotective properties. The recovery of bioactive compounds is significantly affected by extraction methods. Many conventional methods have been explored for the recovering of bioactive compounds from bitter orange flowers. However, in response to the limitations of conventional techniques, green extraction methods, characterized by their ability to significantly increase the yield and reduce the time, energy, and solvent requirements, have also been assessed for this matrix. Therefore, the study of the functionalities of bitter orange blossoms represents a domain with unexplored research opportunities. Consequently, this review aims to offer a comprehensive insight into the biological properties and medicinal applications of the active compounds found within C. aurantium.
