Natural biopolymers have a wide range of uses and bioactivities. In this investigation, karaya gum was gathered and put to use for bioactivity tests. Thin layer chromatography (TLC), a UV-Vis spectrophotometer, and FTIR were used to characterise gum and screen it for phytochemicals. Additionally, it was tested for bioactivity in tests that looked at antioxidant activity and antibacterial activity against S. aureus and E. coli. The antioxidant and antibacterial properties of Karaya gum were effective against S. aureus and E. coli. The presence of sugars such sucrose, glucose, xylose, and other sugars was shown by UV-VIS spectroscopy examination. Alcohol, phenols, aldehydes, and ketones were among the functional groups that were detected using FTIR analysis
