BACKGROUND: Germination is regarded as a natural method for improving the bioavailability of seed nutrients against stress, which enhances the accumulation of bioactive compounds. The present study aimed to determine the effect of stress (H 2 O 2 , catechin, gallic acid, tyrosine, and NaCl) during germination of djulis (Chenopodium formosanum Koidz.) sprouts on betacyanin, phytochemicals, and antioxidant capacities. RESULTS: The betacyanin and antioxidant activities of the djulis sprouts increased significantly compared to seeds. The lowest betacyanin was found in NaCl-stressed sprouts. The djulis sprouts reported the presence of celosianins I and II (50.72%), which was absent in seeds. Hydroxycinnamic acids accounted for > 60% of the total phenolic compounds in sprouts, whereas rutin predominated in the seeds. CONCLUSION: Germination under stress may represent an effective natural method for improving the bioactive potential of sprouts, an alternative to use seeds, in the development of bioactive compounds-enriched healthy foods that are good for public health.
