PHYTOCHEMICAL ANALYSIS AND ANTIOXIDANT PROPERTY OF TRIGONELLA FOENUM, ZEA MAYS AND ORYZA SATIVAAbstract
Plants have been used for centuries as a remedy for human diseases because they contain phytochemical components of therapeutic values. The whole plant of the Trigonella foenum, Zea mays and Oryza sativa were selected for in this study to find out the phytochemicals and antioxidant property. Phytochemicals were extracted using various solvents such as Hexane, Ethyl acetate, and ethanol. Screening of phytochemicals showed positive results for the presence of flavonoid, alkaloid, phenols, coumarins, steroids, and quinones. Free radical scavenging activity was determined using DPPH is a stable antioxidant. Ethyl acetate extract of Zea mays showed better antioxidant activity at a concentration of 100-150 µg followed by ethanol extract. An ethanol extract of Trigonella foenum revealed antioxidant activity at a concentration of 100-150 µg followed by ethyl acetate extract. These activities may be due to the presence of flavonoid, alkaloid, phenols, and steroids in plant extracts. Antioxidant activity was not observed in Oryza sativa.
