Seedling time is an important determinant factor for agricultural practice involves with costing and further growing step of all plant seeds. To improve seeding time, growth character, nutritional value and bioactive compounds relating to biological activity as antioxidant property, priming process is necessary for many plants. This study aims to investigate the nutritional value, bioactive compounds and antioxidant activity of ricegrass cv. Chainat 1 primed with fish protein hydrolysate (FPH) during seedling process. The results found that the nutritional value of ricegrass including protein and ash content was highest at 14 d while fat content increased when seedling time increased. Moreover, ricegrass aged 21 d had the highest content of chlorophyll and carotenoids compared with 7 and 14 d. Phytic acid content was lowest in ricegrass aged 7 d thereafter, it was increased. While, total phenolic content (TPC) was highest in ricegrass aged 7 d which also revealed greater antioxidant activity evaluated by ABTS radical scavenging activity, ferric reducing antioxidant power (FRAP) value and iron chelating activity than ricegrass aged 14, 21 d and primed seed. Therefore, seedling time had a significant impact on TPC and antioxidant activity of ricegrass, especially 7 d. In addition, the ricegrass aged 7 d could be possible to produce functional food products in the future.
