【 摘 要 】

This paper describesmethodologies for the extraction and characterization by TLC, UV-VIS, IR andNMR of bixin from Bixa orellana L. (urucum) seeds. Based on the results,the extraction with NaOH 5% is the fastest, uses low-cost materials, requirestwo to four laboratory hours and is a useful alternative for an experimentalOrganic Chemistry discipline.
