• Studies have suggested antimycobacterial antimicrobial activity in the crude extracts of acacia. 
• Preliminary phytochemical screening and antimicrobial activity of Samanea saman: A study of the aqueous plant extract on three organisms (Escherichia coli, Staphylococcus aureus and Candida albicans) showed inhibitory activity against all the tested organisms. Phytochemical screening revealed tannins, flavanoids, saponins, steroids, cardiac glycosides and terpenoids. The study validates the use of the plant in traditional medicine.
 Antibacterial: A methanol extract from leaves showed a highly significant antibacterial activity in vitro for Xanthomonas pathovars and for human pathogenic bacteria.
 Larvicidal: Of 112 medicinal plant species collected in Thailand, Samanea saman (stem bark) was one of 14 plants that exhibited high toxicity to the fourth instar larvae of Aedes aegypti in preliminary screening.
 Antioxidant: Several extracts of Samanea saman showed the highest antioxidant potential in both DPPH and reducing power assay.
 Anti-Termite: Study of ethanolic extracts of seeds and bark of Acacia collected from the Laurel Farm in Lipa city yielded saponins, tannins, alkaloids, reducing agents – glycosides, carbohydrates. Results showed termite killing activity comparable to solignum.
