Detection and Assessment of Nutraceuticals in Methanolic Extract of Finger (Eleusine coracana) and Barnyard Millet (Echinochloa frumentacea)

摘要

The investigation was carried out to determine the chemical components from methanolic extract of finger millet and barnyard millet genotypes using gas-chromatography mass spectrometry (GC-MS). GC-MS analysis of the methanolic extract led to identification of more than 13 compounds in both the crops together. The major compounds in both millets were found to be (Z,Z)-9,12-octadecadienoic acid (26.80 %), (E)-9-octadecenoic acid (17.37 %), caprolactam (6.69 %) and tetradecanoic acid (6.41 %). Moreover, the barnyard millet genotype VL 232 also showed γ-sitosterol, stigmasterols and campesterols in small percentage (1.49, 0.46 and 0.56 %). Oleic acid (2.47 %) was also present in small amount in finger millet. The detection of these compounds in both small millets highlights the importance of these under-utilized crops in terms of their nutritive value. The results inferred that both finger and barnyard millet extract contain variable patterns of bioactive compounds and could be used as natural antioxidant source for medicinal purposes.
