The purpose of this study was to determine the free amino acid contents, total phenolic contents and antioxidant activity in raw Sesamum indicum seeds (cv. Kopum and cv. Mihuk) and their sprouts germinated for 7 days. Total free amino acid contents of sprouts (29.34±3.3 mg/g DW) were significantly higher than that of raw seeds (6.85±0.39 mg/g DW). All individual free amino acid, including asparagine, alanin, arginine, and leicine were significantly increased in the sesame sprout. And also germinated sprout significantly increased the total phenolic contents (2.2±0.3 mg GAE/g) that resulted in the increased DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging capacity. Subsequently, two varieties of sesame and its sprouts were analyzed for their phenolic constituents using high-performance liquid chromatography (HPLC). Catechin, sinapic acid and salicylic acid were identified as the major phenolic acid presented in sesame sprout. However, the major biological constituents sesamin and sesamolin content were significantly decreased during germination.
