In the heart of Morocco, researchers are unlocking the secrets of a humble plant that could revolutionize industries reliant on corrosion prevention and natural antioxidants. Pistacia lentiscus L., a medicinal and aromatic plant, is the subject of a groundbreaking study led by Mouhcine Hayani from the Research team of Chemistry of Bioactive Molecules and the Environment at Moulay Ismail University in Meknes. The findings, published in the journal ‘Green Chemistry Letters and Reviews’ (or in English, ‘Letters and Reviews on Green Chemistry’), could pave the way for eco-friendly solutions in the energy sector and beyond.
The study delves into the phytochemical composition, antioxidant potential, and corrosion inhibition properties of P. lentiscus extract. Using the decoction method for extraction, Hayani and his team identified key bioactive compounds such as tannins, flavonoids, alkaloids, sterols, and triterpenes. High-performance liquid chromatography (HPLC) revealed six phenolic compounds, with gallic acid being the most abundant, followed by rutin and parahydroxybenzoic acid.
The antioxidant activity of the extract was evaluated using DPPH and FRAP assays. The results were promising, with the extract exhibiting an IC50 value of 4.18 µg/mL in the DPPH assay, comparable to ascorbic acid. “The antioxidant potential of P. lentiscus extract is remarkable,” Hayani noted. “It suggests significant therapeutic applications, particularly in industries where natural antioxidants are in high demand.”
In silico molecular docking studies further highlighted the potential of the extract. Rutin and gallic acid showed the highest binding affinities with the 4M6J active site, indicating their potential as bioactive compounds. The extract also demonstrated an impressive 83.26% corrosion inhibition efficiency on carbon steel in 1M HCl, a finding that could have substantial implications for the energy sector.
Corrosion is a significant challenge in industries such as oil and gas, where metal structures are constantly exposed to harsh environments. Traditional corrosion inhibitors often contain toxic chemicals that pose environmental and health risks. The use of natural, eco-friendly inhibitors like P. lentiscus extract could provide a sustainable alternative.
“This research opens up new avenues for the development of green corrosion inhibitors,” Hayani explained. “The use of plant extracts not only reduces environmental impact but also leverages the natural properties of these compounds to enhance efficiency.”
The study’s findings suggest that P. lentiscus extract holds significant potential for therapeutic and industrial applications. As industries increasingly seek sustainable and eco-friendly solutions, the use of natural resources like P. lentiscus could become a cornerstone of green chemistry.
The research published in ‘Green Chemistry Letters and Reviews’ not only highlights the phytochemical richness of P. lentiscus but also underscores the importance of exploring natural resources for industrial applications. As the world moves towards sustainability, the insights gained from this study could shape the future of corrosion inhibition and antioxidant therapies, offering a glimpse into a greener, more sustainable industrial landscape.
