Salvia hispanica (Chia Seed) also known as chia seed, is an annual herbaceous plant, originallyfrom Southern Mexico. Chia seeds have become one of the world’s most recognizable foodsbased on their nutritional properties and medicinal values.Cyperus esculentus L. (Tiger Nut) isavaluable food for nourishment with significant health benefits, they are rich in vitamins andminerals. In this study, phytochemical and antioxidant vitamins A, C and E compositions of ChiaSeed and Tiger nut procured from Nnewi, Anambra State were evaluated using standard methods. Phytochemical and bioactive contents of the samples were determined usingGaschromatography- flame ionization detector while antioxidant vitamins (A, C, E) were determinedusing Pearson method. Data obtained from the experiments were analyzed using the Statistical
Package for Social Sciences (SPSS) version 26. Level of significance was set at p<0.05. Theresults of this study revealed that chia seed and tiger nut possess good quantity of antioxidant
phytochemicals such as quercetin (6.86 ± 0.00 and 0.83 ± 0.00)ppm, nobeletin(1.21 ±0.00and0.15 ± 0.00)ppm, resveratrol (0.32 ± 0.00 and 2.04 ± 0.00)ppm, vanillic acid (0.14 ±0.00and18.28 ± 0.00)ppm respecvtively and antioxidant vitamins A (13.28 ± 0.02 and 25.00±0.02)mg/l, C ( 117.65 ± 0.25 and 109.09±0.21)mg/kg and E (19.73± 0.02 and 31.49± 0.02)mg/l respectively. In conclusion,the results of this study revealed that chia seed and tiger nut possess good quantityof antioxidant phytochemicals and antioxidant vitamins and therefore could be very useful inneutralizing the free radicals normally generated in some disease conditions,henceinmanagement of oxidative stress.
