“…Besides, the goal is to recycle ZM waste. In the presence of HE (AV) and HE (ZM) taken separately, the current densities are 49.81 µA cm −2 and 82.56 µA cm −2 , respectively [10,14]. However, i corr decreases significantly with the formulation which means that mild steel corrosion is intensely delayed by these inhibitors' mixture, and a strong synergism inhibitory effect is obtained between HE (AV) and HE (ZM).…”

“…We have taken the best concentration of HE (AV) which gave the best inhibition effect and it mixed with different concentrations of HE (ZM) until the inhibiting effectiveness achieved its maximum. Indeed, the objective is to recover the Z. mays waste which is characterized by a better yield as well as by important polyphenolic content especially flavonoids when compared to the HE (AV) extract [10]. ese measurements were carried out under the same conditions as those used for HE extracts alone.…”

“…However, plant extracts have become a more important corrosion inhibitor due to their low toxicity, high availability, and simple preparation [5]. According to the literature [7], most recent contributions are those using plant extracts to inhibit corrosion of steel in acid solutions, for example, Ammi visnaga extract [8][9][10], corn silk [11], and a mixture of Hevea brasiliensis (rubber) and leaf of Zea mays (corn cob) [12]. It is clear from these studies that the inhibitory properties of plant extracts are generally attributed to their variety and complex organic substances [13].…”

“…It is clear from these studies that the inhibitory properties of plant extracts are generally attributed to their variety and complex organic substances [13]. Recently, we presented electrochemical experimental evidence demonstrating that the hydroethanolic extract of Ammi visnaga [10] and the hydroethanolic extract of Zea mays hairs acted as a good corrosion inhibitor on mild steel in 1 M HCl solution [14]. PP studies have shown that HE (AV) functions as a mixed-type inhibitor and HE (ZM) acted as a mixed-type inhibitor with anodic predominant action in the hydrochloric acid system.…”

The synergetic effects between hydroethanolic extracts of A. visnaga HE (AV) and Z. mays hairs HE (ZM) on corrosion of mild steel in 1 M HCl solution was investigated at 298 K by two techniques: potentiodynamic polarization (PP) methods (Tafel and Stern & Geary) and electrochemical impedance spectroscopy (EIS). The mixture of HE (AV)/HE (ZM) acted as an efficient corrosion inhibitor and its inhibition efficiency increased with concentration up to 96.55% at 0.01 gL−1 HE (AV)/0.2 gL−1 HE (ZM). The polarization curves revealed that the mixture acted as a mixed-type inhibitor, with anodic predominant action. The EIS studies were fitted by the (Rs + CPEdl)/(Rct + CPEf/Rf) equivalent circuit model. The kinetic parameters were in favor of a physisorption character of adsorption of HE (AV)/HE (ZM) components onto the mild steel surface. The influence of exposure time on the efficiency of mixture extract was investigated. Scanning electron microscopy (SEM/EDX) analyses confirmed the formation of a protective adsorbed film upon the mild steel surface.

Medicinal plants have a vital role in our life, providing us with a variety of secondary metabolites with varied chemical structures and biological activities. Ammi visnaga (L.) Lam. and Apium graveolens L. are common traditional plant species that have long been used for the prevention and treatment of several health problems. Both A. visnaga and A. graveolens belong to the carrot family, Apiaceae (Umbelliferae) and showed different groups of natural compounds, such as coumarins, furanochromones, flavonoids and essential oils. In view of that, the current review describes various classes of chemical constituents identified so far from these medicinal species, together with their valued pharmacological and therapeutic effects.

The study objective was to analyse the phytochemical constituents in aerial extracts of these plants using an HPTLC method and optimization by quality by design. Qualitative analysis of ephedrine in hydro-alcoholic extract was done via HPTLC, using a mobile phase of toluene-ethyl acetate-chloroform-formic acid in the ratio of 1:0.5:0.5:01 and the peaks were monitored at 366 nm. In the hydro-alcoholic aerial part extract, ephedrine was identified using the HPTLC method and the retardation factor (Rf) value was found to be 0.69 ± 0.01 and 0.69 ± 0.01, as compared with the standard sample. The extraction of plant materials was done using different concentration of water and alcohol solvents and quality by design was applied to optimize the extraction process and to find out the best extraction in an 80:20 ratio of hydroalcoholic extract. In the hydro-alcoholic extract, the ephedrine was characterized using the HPTLC method and compared with the standard solution, and this method was used in herbal as well as academic research for the identification of ephedrine in poly herbal formulations as well as the ephedrine present in different plant extracts.Response surface methodology software was utilized to predict the path or choose the best extraction method. Sida rhombifolia and Sida cordifolia can be used as substitutes for Ephedra gerardiana based on the HPTLC profile.
