Abstract
Roselle (Hibiscus sabdariffa L.) has been shown to have various bioactivities with therapeutic benefits. These bioactivities are owing to the different kinds of phytochemicals, which include anthocyanins, phenolic acids, and flavonoids. This mini review aims to summarize the reported antibacterial activity of roselle phytochemicals in the literature in the past decade (2011-2021). The results revealed that roselle extracts from various extraction methods were shown to have antibacterial activity against clinical isolates and food pathogens, including multidrug resistant bacteria. Furthermore, there is evidence that roselle extract showed potential synergy with antibiotics. Overall, phytochemicals in roselle have the potential as an antibacterial for different beneficial applications.
