Anticorrosive and antifungal effects of ethanolic extract (stem /leaf) of tinospora cordifolia plant in hno3 acid using additive (kno3)

Weight loss and thermometric techniques were used in the absence and presence of an additive (KNO3) to test the corrosion-inhibitory effectiveness of Tinospora Cordifolia stem and leaf extract in various concentrations of HNO3 acid (0.5, 1, 2, and 3N). The results of this study indicate that inhibition effectiveness (ɳ%) increases with both increasing inhibitor concentration and acid strength, and that a further improvement in inhibition efficiency was observed with the addition of additives (KNO3) due to a synergistic effect. Based on the research, stem extract outperforms leaf extract as a corrosion inhibitor. In the absence of an additive and using 3N HNO3 acid at its maximum strength, the greatest inhibitory efficiency was seen for stem and leaf extracts at their maximum concentrations (0.8%) of 90.46% and 86.51%, whereas it was shown at 93.48% and 90.69% in the presence of an additive (KNO3). The disc diffusion method was used to investigate the in vitro antifungal activity of the Tinospora Cordifolia stem and leaf extract against Aspergillus niger. Interpretations from the zone of inhibition revealed that Tinospora Cordifolia stem and leaf extract has good antifungal efficacy against Aspergillusniger (a fungus).
