ABSTRACT

Cereal grass and its ingredients are gaining popularity as functional and nutraceutical foods. Barley grass (BG) juice is known as a super food as it provides dietary supplements to protect age related diseases such as diabetes, cardiovascular diseases, etc. The present study was conducted to evaluate the phytochemical profile of the green grass barley (Hordeum vulgare L.) grown in normal soil and soil containing different fruit peel of banana, pomegranate, pineapple and lemon over a period of 13, 15, 17 and 21 days. Quantitative profiling especially the antioxidant profiles such as total phenolic contents (TPC), flavonoids, ascorbic acid and free radical scavenging activity were studied. The results portrayed the antioxidant profile of BG to be different on normal soil and the soil fortified with fruit peels. The highest phenolic values were observed on 17th day in soil with banana peels (0.432±0.01mg TAE/gm) followed by pomegranate (0.312±0.02mg TAE/gm), pineapple (0.306±0.03mg TAE/gm) and lemon peels. The highest FRAP values occurred on day 13 of growth in soil with pineapple peels (4.959±0.07mgAAE/gm) and normal soil whereas in soil with lemon (4.039±0.07mg AAE/gm) and pomegranate (3.94±0.01mg AAE/ gm) the highest levels were observed on 15th day. Keywords: antioxidant, flavonoid, phenolic, ascorbic acid, barley grass
