A significant part of the prevention and treatment of human diseases is played by antioxidant phytochemicals. Screening and identifying these chemicals from various plant species is the first step in realising their therapeutic potential. This study examined the presence of strong antioxidant phytochemicals in the invasive plant species Lanata camera. Total phenol, total flavonoid, and total alkaloid content of Lanata camara leaves extracts as well as antioxidant potential (total antioxidant activity, iron chelating activity, and enzymatic activity), were investigated (peroxidase and polyphenol oxidase).The extract had a high level of free radical scavenging activity however whole leaves extracts had a little greater quantity of antioxidants.Crude extracts were analysed chemically using FTIR, UV-Visible spectroscopy. The presence of numerous functional groups, such as N-H, C-H, -OH and C = O in the extracts from Lanata camera leaves as indicated by FTIR spectral analysis suggests the presence of multiple metabolites. As a result, extracts from Lanata camera leaves have the potential to play a significant role in the treatment of human ailments
