Natural colourants with bio-potential are of great commercial demands as we are moving away from the hazardous and toxic chemical dyes. Bixa orellana L. a representative of Bixaceae is rich in bixin and nor-bixin pigments which could be explored for various applications. In the present study, extraction and characterization of bixin and its associated pigment from the aril of the B. orellana L. seeds were performed using various spectroscopic techniques. Spectroscopic analysis and Gas chromatographic profiling of the pigment were performed to understand the present pigments. Toxicity was evaluated through in silico method. The major component, bixin and nor-bixin were proved to be non-toxic, non-carcinogenic and non-mutagenic through in silico methods. The pigment was found to be a potent antioxidant as well as bactericidal against opportunistic bacteria. It was found that bixin extract was a potential antioxidant and bactericidal agent. Hence it could be used for imparting bactericidal potential for cellulosic materials like papers or textiles in biomedical applications.
