“…Alkaloids constitute one of the widest class of natural products, being synthesized by many living organisms. Many research groups employed alkaloids extracts as green corrosion inhibitors due to the presence in their molecular structure of at least one nitrogen atom [65,70,83,91,96,97,107,108,109]. Due to the presence of lone pair electrons of heteroatoms and its interaction with the vacant d-orbital of the metal to be protected that are fundamental factors in the effective inhibition.…”

“…The authors then discussed some hypotheses about the mechanism of corrosion inhibition depending on the protonation of the molecule and hence its charge distribution on the molecule. Fdil and co-authors published two papers, in 2015 [97] and 2018 [96], about alkaloids extract of Retama monosperma (L.) Boiss. seeds and stems, used as novel eco-friendly inhibitor for carbon steel corrosion in 1 M HCl solution.…”

Green Corrosion Inhibitors from Natural Sources and Biomass Wastes

Over the past decade, green chemistry has been emphasizing the importance of protecting the environment and human health in an economically beneficial manner aiming at avoiding toxins and reducing wastes. The field of metallic materials degradation, generally faced by using toxic compounds, found a fertile research field in green chemistry. In fact, the use of inhibitors is a well-known strategy when metal corrosion needs to be prevented, controlled, or retarded. Green inhibitors are biodegradable, ecologically acceptable and renewable. Their valorization expands possible applications in industrial fields other than ‘waste to energy’ in the perspective of circular economy. Although lot of experimental work has been done and many research papers have been published, the topic of green inhibitors is still an open issue. The great interest in the field expanded the research, resulting in high numbers of tested molecules. However, the most frequently adopted approaches are conventional and, hence, not suitable to fully characterize the potential efficacy of inhibitors. All the mentioned aspects are the object of the present review and are meant as a constructive criticism to highlight the weak points of the green inhibitors field as to re-evaluate the literature and address the future research in the field that still lacks rationalization.

Corrosion of macro to micro-structures has been one of the major causes of structural failure in modern era. Their early detection could assist in limiting their repairs and reducing the associated cost as well. This chapter focusses on the state-of-the-art and development made with green corrosion inhibitors for preventing corrosion. It mainly includes the most recent progress in electrochemical corrosion monitoring techniques for various green inhibitors namely polarization technique, electrochemical impedance spectroscopy, electrochemical noise measurement and electrochemical quartz crystal microbalance techniques. Finally, we conclude with the current progress, limitations and remedies in the recent trends and advancement of green corrosion inhibitors for corrosion prevention.

“…R. monosperma has attracted considerable interest due to its wide range of pharmacological properties, including antioxidant [ 17 ], anti-aging [ 3 ], antibacterial [ 18 ], antifungal [ 19 ], anti-inflammatory, antiproliferative, and antitumoral [ 3 , 11 , 20 ], as well as antileukemic activities [ 21 ]. The principal alkaloids of R. monosperma are retamine, sparteine, dehydrosparteine, ammodendrine, N-methylcytisine, cytisine, isolupanine, and anagyrine [ 22 ], flavonoids such as genistein, quercetin, 6-methoxykaempferol, and kaempferol [ 16 ], fatty acids from the seeds’ hexane extract, such as myristic, pentadecylic, oleic (omega-9), linoleic (omega-6) and linolenic (omega-3) [ 23 ].…”

“…In addition, this plant showed potent antimicrobial effects and could be used to formulate medicinal plants for the management of various infectious conditions. It has been reported that hexane and dichloromethane extracts of seeds showed a very significant (Ø > 14 mm) antibacterial effect against Bacillus sp and E. coli , while the ethyl acetate extracts of the stems and the flowers exhibited very significant activity on Salmonella sp [ 18 ]. As an antifungal activity, alkaloids of R. monosperma play a significant role in the reduction of C. albicans and C. tropicalis growth.…”

Retama monosperma L. (Boiss.) or Genista monosperma L. (Lam.), known locally as “R’tam”, is a spontaneous and annual herb that belongs to the Fabaceae family. It is native to the Mediterranean regions, specifically in the desert areas and across the Middle Atlas in Morocco. This plant has been extensively used in folk medicine and it is rich in bioactive compounds, including polyphenols, flavonoids, and alkaloids. Current research efforts are focusing on the development of novel natural drugs as alternatives to various organic and non-organic chemical products from Retama monosperma. In addition, extract, and isolated compounds obtained from different parts of the chosen plant have been described to exhibit multiple biological and pharmacological properties such as antioxidant, anti-aging, anti-inflammatory, antihypertensive, anti-helminthic, disinfectant, diuretic, and hypoglycemic effects. The plant-derived extract also acts as an antimicrobial agent, which is highly efficient in the treatment of bacterial, viral, and fungal infections. Its antiproliferative effects are associated with some mechanisms, such as the inhibition of cell cycle arrest and apoptosis. In light of these assessments, we critically highlight the beneficial effects of the flowers, stems, seeds extracts, and isolated compounds from R. monosperma (L.) Boiss in human health care, industrial, and other applications, as well as the possible ways to be employed as a potential natural source for future drug discovery.
