“…It is often considered as a weed in fields and gardens. Milky juice of the plant contains taraxacin and taraxacerin, 2–3% rubber substances, while blossoms and dandelion leaves are rich in taraxasterol, flavoxanthin, vitamins (C, A, B2, E), choline and saponines, and roots are rich in triterpene compounds (taraxasterol, taraxerol, pseudotranslation, β-amyrin) and sterols (β-sitosterol, stigmasterol, tarksol) [ 60 , 61 ].…”

The development of new effective anti-coronavirus drugs and therapies is important, but it requires significant human, financial and, most importantly, time expenditures. The current pandemic is neither the first nor the last. Humanity has already accumulated considerable survival experience. We cannot do without prevention and epidemiological protection measures. This study reviews medicinal plants that grow in Northeast Asia and whose antioxidant, antiviral, anti-inflammatory and immunomodulatory characteristics are already known, also in the framework of the prevention and treatment of pneumonia of various etiologies. The need for a comprehensive approach to maintaining immunodefences, including functional foods and positive emotions, is emphasized. In the period of pandemics, it is important to research various areas that allow to us accumulate a critical mass of information and cope with the next global disease.

“…The TOE extract is predominantly composed of a few of organic compounds. Several studies have reported the composition of different parts of Taraxacum officinale plant for nutritional facts and presence of vitamins and active principles 25,27 . The extraction process obviously influences the composition of the solution: Jung et al 33 compared the 1 H NMR profiles of aqueous and organic extracts (for another species of Taraxacum plant, T. coreanum); Kenny et al also observed substantial differences in the extracted species while using aqueous or solvent extracting agents 29 .…”

The aqueous extract is mainly constituted of saccharides such as glucose, sucrose; however, many other amino-acids, polyphenols 26 , flavonoids 25 and organic acids 28 are also identified. The current analysis of the TOE extract by HPLC shows the main compounds of the corrosion inhibitor ( Fig.…”

“…In this work, a new bio-sourced extract has been investigated for the first time for preventing corrosion of carbon steel in aggressive environment (desalination plant conditions). This extract (TOE) was obtained from Taraxacum officinale, which is a compound used in Chinese medicine and in various modern pharmaceutical formulations 24,25 . Taraxacum officinale is well known for its antioxidant activity, having a high content of polyphenols such as sesquiterpene, lactones, phenylpropanoids, triterpenoid saponins and polysaccharides 26,27 .…”

Taraxacum officinale extract (toe) has been tested for preventing the corrosion of cooling systems in desalination plants. The inhibition of corrosion effects has been characterized by chemical and electrochemical methods (Mass loss, potentiodynamic polarization and electrochemical impedance spectroscopy) and surface observations. tests on cooling systems were carried out in seawater environment. the presence of toe in the re-circulation loop decreases the corrosion of carbon steel by adsorption of toe compounds on the surface of metal pipes. the optimum toe concentration was reached at 400 mg L −1 and the inhibition efficiency was higher than 94%. TOE allowed increasing the energy barrier of the corrosion process. SEM, FT-IR and UV spectra observations confirmed that TOE prevents corrosion attacks at the surface of the pipes. HPLC analyses identified the presence of saccharides, organic acids, phenol antioxidant and caffeic acid derivatives in TOE, which may be the active promoters of corrosion inhibition. www.nature.com/scientificreports www.nature.com/scientificreports/ R ct cto ct where R ct and R cto are the charge transfer resistances in the presence and absence of TOE, respectively.

Objectives: Dandelion has been shown to exert anti‐inflammatory and anti‐bacterial effects. Our study aimed to identify the effect and mechanism of dandelion flower extracts on H. pylori‐induced gastritis and screen for novel antimicrobial substances. Methods: Anti‐H. pylori activities of water extracts(WEDF) and ethanol extracts (EEDF) of dandelion flowers were performed with disk diffusion method assay, MIC, and MBC. The H. pylori‐induced model was constructed to examine the gastroprotective of EEDF using RUT, pathological analysis, and ELISA. Results: EEDF exhibited better anti‐ H. pylori and urease inhibition activities than WEDF. In vivo studies, EEDF can reduce the adhesion of H. pylori to the gastric mucosa, alleviate gastric damage, and concurrently reduce the levels of TNF‐α and IL‐6 in gastric tissues. The six phenolic compounds showed urease inhibition effect (IC50: 2.99 ± 0.15 to 66.08 ± 6.46 mmol/mL). Among them, chlorogenic acid, caffeic acid, and luteolin also had anti‐H. pylori activity (MIC: 64 ‐ 256 μg/mL). Conclusion: EEDF exhibited anti‐H. pylori, gastroprotective and anti‐inflammatory effects. Chicoric acid and luteolin may be the main active compounds of dandelion flowers to exert anti‐H. pylori, and worthy of further investigation.
