This study was conducted to investigate the physicochemical characteristic of Carthamus tinctorius L. seed and to assess its total phenol content, total flavonoids content and antimicrobial activity. The moisture, crude protein, crude fat, crude ash and carbohydrates of the Carthamus tinctorius L. seed were 5.58, 37.16, 13.69, 3.52, and 40.05%, respectively. Total amino acid in Carthamus tinctorius L. seed was 391.99 mg%. The major free sugar of Carthamus tinctorius L. seed were fructose(3.29%) and sucrose(1.74%). Linoleic acid(79.46%) was a major fatty acids in the crude fat of Carthamus tinctorius L. seed. The K and Ca contents were the highest in Carthamus tinctorius L. seed. Total phenol and total flavonoids contents of the ethanolic extract were 55.52 ± 0.99 mg GAE/g and 78.69 ± 0.91 mg QE/g, respectively. The extract from Carthamus tinctorius L. seed showed growth inhibitory effect on Staphylococcus aureus, Salmonella typhimurium, Escheria coli, Candida albicans, Bacillus cereus, Listeria monocytogenes, Vibrio parahaemolyticus, and Clustridium perfringens. These results indicate that the Carthamus tinctorius L. seed extract can inhibit food pathogen associated with total phenol and total flavonoids contents.
