Research has been conducted on the extraction of bioactive compounds from propolis, a substance produced by bees. Various studies have explored the properties and potential uses of propolis, including its antioxidant and antibacterial activities, as well as its interactions with other substances. The use of subcritical water for extracting bioactive compounds from propolis is one area of focus, although the scope of the research appears to be broader, encompassing multiple aspects of propolis and its applications.
