Millettia aboensis leaves extract as eco-friendly corrosion inhibitor for mild steel in acidizing solution: From experimental to molecular level prediction

The development of environmentally friendly corrosion inhibitors is becoming more popular since conventional inhibitors are poisonous and non-biodegradable. The anti-corrosive effectiveness of Millettia aboensis leaves extract (MALE) has been assessed in this study using several methods, such as electrochemical measurements, X-ray Photoelectron spectroscopy and scanning electron microscopy on mild steel in acidic solution. Gas chromatography-mass spectrometry (GC-MS) analysis was combined with qualitative and quantitative phytochemical analysis to identify the phytochemicals linked to the activity of the Millettia aboensis extracts and identified key phytoconstituents such as Hexanedioic acid, Phenol derivatives, Octadecanoic acid, and Linolenic acid, which play significant roles in the extract's inhibitory performance. The results showed that the inhibition efficiency (IE%) improved to 88.6 % with the addition of inhibitor concentration from 0.1 g/L to 3.0 g/L and that the corrosion rate drastically reduced from 56.91 mpy to 16.09 mpy. Furthermore, at a greater concentration (3.0 g/L), the Rct values rose from 61.42 Ω cm2 to 176.3 Ω cm2 thus, indicating that the inhibitor molecules were forming a protective film over the metallic surface. Scanning Electron Microscopy (SEM) provided visual evidence of surface morphology, revealing a smoother surface in the presence of the inhibitor, indicative of the protective film formed by the adsorption of organic molecules onto the steel surface. Theoretical calculations using the ωB97XD functional and def2svp basis set further supported the experimental findings, showing that the protonated form of C21H36O4 exhibited the highest interaction energy, correlating with its superior inhibition efficiency on the metal surface.

Compared to the control drug, the ethyl acetate fraction of Coccinia barteri leaf gave a 2-fold lower IC50. GCMS chromatogram of the most active sub-fraction revealed the presence of 18 major compounds. Piperine showed good binding affinity (−6.9 kcal/mol) to α-amylase and displayed hydrogen bonding with ARG 344 and HIS 210, along with pi alkyl bonds with TRP 83, HIS 80, LEU 166, and LEU 232. For α-glucosidase, piperine and 2,4-di-tertbutylphenol surpassed the standard with binding energies of −7.1 kcal/mol and - 6.9 kcal/mol, respectively. Drug likeness and toxicity assessments confirmed adherence to Lipinski's rule, with both compounds showing non-mutagenic and non-tumorigenic properties. Conclusion The ethyl acetate fraction of the Coccinia barteri leaf exhibits potential anti-diabetic activity, which may be attributed to the inhibition of α-amylase and α-glucosidase, by its constituents, piperine and 2,4-di-tertbutylphenol.

Phytochemical Analyses and Antibacterial Activities of Jatropha tanjorensis J. L. Ellis and Saroja Leaves Extract against Clinical Pathogens

Aim: The aim of this study was to investigate the phytochemical and antimicrobial characteristics of leaf extracts from Jatropha tanjorensis plant against some selected clinical pathogens. Study Design: Experimental Study design (Quantitative). Place and Duration of Study: Sample: The bacteria were obtained from the stock culture of the Microbiology laboratory at LUTH, Idi-Araba, Lagos State and Department of Biological Sciences, Bells University of Technology, Ota, Ogun State. Methods: Fresh Jatropha tanjorensis leaves were obtained, identified, and then finely ground after being dried at room temperature. To obtain the extracts, two hundred grams (200g) of the leaves were macerated in one thousand milliliters (1000ml) of solvent. Phytochemical analyses were done on the extract utilizing suitable standard protocols. Using the agar well diffusion method, the leaf extracts' antibiotic sensitivity was assessed against selected bacteria, including Salmonella typhi, Pseudomonas aeruginosa, Bacillus subtilis ATCC 6633, Enterococcus faecalis FELAO97, Escherichia coli, Bacillus aureus ATCC 25923, and Bacillus aureus ATCC 25923. Results: The qualitative phytochemical analysis revealed that while phlobatannins were absent from all extracts, other compounds found included saponin, alkaloids, phenols, flavonoids, reducing sugars, terpenoids, steroids, and tannins. According to the quantitative phytochemical analysis, reducing sugars from methanolic extract had the lowest concentration (20.39 mg/100g) and flavonoids from hot water extract had the highest concentration (98.55 mg/100g). With a zone of inhibition of 19.83 mm against S. aureus, the cold-water extract exhibited the highest inhibitory effect, while the methanolic extract displayed the lowest zone of inhibition, 13.17 mm, against B. subtilis. When compared to other isolates, B. subtilis had the lowest MIC value of 10.24 mg/ml and other isolates had the highest MIC value of 20.48 mg/ml. A GC-MS analysis identified fifty-seven (57) bioactive compounds with 1, 2, 3-Benzenetriol having the highest percentage of 66.38%. Conclusion: This study suggests that Jatropha tanjorensis may be a potential antibacterial drug, but more thorough study and collaboration are still necessary.
