Abstract
Legumes are known as protein rich food, however some of the species have not been used broadly, including jack beans (Canavalia ensiformis), due to the content of anti-nutrients compounds. The purpose of this study was to investigate profile of phenolics and non-protein amino acid in jack bean that were considered as anti-nutrients. The methods used include extraction of jack bean using methanol and analysis of phenolics and non-protein amino acid using UPLC-ESI-QTOF. The result showed that MeOH extract of the jack beans contain phenolic acid compounds, flavonoids, and non-protein amino acids, including canavanine. Canavanine is an amino acid that has similar structure to arginine, so that might interfere with the function of the protein.
