## Abstract

Infectious diseases present a significant global health challenge, further exacerbated by the rising prevalence of antimicrobial resistance and the limited availability of effective antiviral and antimicrobial agents. The Erythrina genus has garnered scientific interest due to its diverse array of bioactive phytoconstituents, with potential therapeutic relevance. This review aims to synthesize and critically assess the existing literature on the antiviral, antibacterial, antifungal, and antiplasmodial properties of Erythrina species. A comprehensive literature search was conducted using PubMed, Scopus, and Google Scholar databases. Relevant studies were identified through keyword searches combining pathogen-specific terms with “Erythrina”. The extracted data were categorized based on the pathogen type and its associated bioactive compounds. Several Erythrina species exhibited substantial antiviral activity against prominent viral pathogens, such as HIV and SARS-CoV-2. Notably, strong antibacterial efficacy was observed against Staphylococcus aureus, including multidrug-resistant strains. Antifungal activity was most pronounced against Candida albicans, while potent antiplasmodial effects were reported against both drug-sensitive and drug-resistant strains of Plasmodium falciparum. These pharmacological effects were predominantly attributed to prenylated flavonoids, isoflavones, pterocarpans, and erythrina-type alkaloids. Further mechanistic studies and in vivo evaluations are essential to fully assess their clinical efficacy and support the development of plant-derived antimicrobial agents.
