Evaluation of Antioxidant and Anticorrosion Activities of Ligularia Fischeri Plant Extract

Ariviyal Publishing Journals ISSN: 2582-3353 Abstract: The use of plant as antioxidant and green inhibitors is a huge topic of discussion by many around the world. A major search for natural and green products are taken seriously as it has numerous benefits than any other man made product to prevent oxidation and corrosion. The use of plant extract of Ligularia fischeri (L. fischeri) was investigated in various aspects to identify the potential in scavenging free radical and protecting aluminum specimen from 1M HCl. On investigating the TPC-TFC of L. fischeri, 253.11-102.18mg/g of each were found. The antioxidant assays like DPPH (89.2%), nitric oxide (83%), and hydrogen peroxide (83%) free radical scavenging were comparatively good to that of the standard ascorbic acid. Weight loss measurements proved that the L. fischeri is effective at 1000 ppm of concentration with 1M HCl at 303±1 K. The maximum inhibition efficiency of 91.90% was achieved. The AFMSEM analysis showed the inhibiting nature of L. fischeri by forming protective layer on the surface of steel.
