  • The objective of this study was to investigate the worth of extract husk and cobs of the Seakso 1 (EHCS) for the functional foods. We aimed to investigate the proximate composition, fatty acids, amino acids, antioxidant active substance contents, antioxidant activity, inhibitory activity of the ${\alpha}-amylase$ and ${\alpha}-glucosidase$. The proximate composition of the EHCS have represented 6.90% moisture, 7.31% crude ash, 0.52% crude fat and 7.07% crude protein. Among the 17 kinds of amino acids that were analyzed in thd EHCS, the glutamic acid was the highest, with 736.08 mg / 100 g. The fatty acids detected in the EHCS were palmitic acid oleic acid and linoleic acid. The proportion of the unsaturated fatty acids was 83.33%. We determined the contents of the antioxidant active substance by the total polyphenol and flavonoid. The total polyphenol and flavonoid contents were 99.87 mg/g and 25.02 mg/g, respectively. The antioxidative activity of the EHCS were determined using a DPPH and ABTS assay. In the antioxidative activity determination, the DPPH and ABTS radical scavenging activities were 95.62% ($1,000{\mu}g/mL$) and 92.00% ($10,000{\mu}g/mL$), respectively. The inhibitory activity of ${\alpha}-amylase$ and ${\alpha}-glucosidase$ (10 mg/mL) were 95.86% and 76.92%, respectively. These results suggest that the EHCS could be potentially used as a resource for the bioactive materials for health functional foods.
