The proximate composition, anti‐oxidants profile of triticale cultivars in Saudi Arabia were evaluated. protein, ash, fat, fiber, and carbohydrates were observed. A wide range of mineral elements were detected, the most abundant was potassium followed by phosphorus. Total phenolic content of the tested cultivars ranged from 1.54 to 2.35 mg GAE/g. The DPPH radical scavenging effects of the triticale were all high. The free RAS as a proportional of total estimated RAS ranged from 41.98% to 48.84%. Compared to free RAS, higher levels of bound RAS were found in all samples. Total phenolic content of tested triticale cultivars were strong positively correlated with DPPH activity. TPC was negatively correlated (r ¼ _0.41; p > 0.1) with bran yields in triticale lines studied, indicating that variation in phenolic was not only due to bran yields but also to genotypic differences. Significant differences in total flavonoids content were found in all triticale cultivars, where ST4 had the highest content i.e. 34.34+0.60 and ST20 exhibited the lowest content i.e. 6.59 +0.51. The color results showed that triticale grains varied in color. As a result of our experiments, we can conclude that the triticale's should be explored for commercial exploitation in bio fortification programs and may serve as sources of valuable phenolic for food and nutraceutical applications
