Traditional medicine has long recognized the therapeutic potential of Cnicus benedictus , and recent scientific research has shed light on the pharmacological properties of this plant. The bioactive compounds that can be extracted from it, such as the sesquiterpene lactones arctigenin, arctiin, and cnicin, are very interesting to researchers.In this article, based on available data from pre-clinical in vitro and in vivo studies, we delve into the pharmacology of the active constituents of this plant to explore its potential therapeutic applications and underlying mechanisms of action. In addition, we present a computer analysis designed to reveal the pharmacokinetic and toxicological properties of the main phytochemicals that are active in C. benedictus through new in silico techniques and predictive tools such as SwissADME and PubChem.The data from the in silico study presented here support the traditional use of C. benedictus , as well as its promise as a source of new therapeutic chemical compounds.

Mechanistic basis
This use is associated with the plant's anti-inflammatory action. Further evidence for that pharmacology:
The phenolic composition of Cnicus benedictus roots from four Algerian regions was investigated. Extractions were performed in both hydro-methanolic (30 : 70, v/v) and hydro-ethanolic (30 : 70, v/v) solvents. Their efficiency was determined in terms of the qualitative and quantitative composition in phenolic compounds by HPLC-LC/MS of the different extracts isolated from C. Benedictus roots. Cnicus benedictus roots extract have been characterized by high content of phenolic compounds, where the trans chalcone, 2,3-dihydro flavone, 3-hydroxy flavone and cinnamic acid constitute the major components, in addition to fourteen minor acidic compounds and flavonoids as rutin. The hydro-methanolic extract was the richest in phenolic compounds yield from C benedictus. On the other hand, hydro methanolic (30 : 70, v/v) and hydro ethanolic (30 : 70, v/v) extracts exhibited a high anti-inflammatory activity by in vitro 5-lipoxygenase inhibitory activity (IC 50 : 6.05±94.16 μg/mL) as well as by in silico docking according two methods. Likewise, anti-Alzheimer activity of extracts was confirmed by this last technique taking into account the major compounds identified. Antibacterial tests revealed interesting results compared to amoxicillin for the different regions studied with a high content in trans chalcone and 3-hydroxy Flavone.
This study evaluated the biological activities of Eryngium planum and of Cnicus benedictus extracts enriched in polyphenols obtained by nanofiltration. The HPLC-MS analysis showed that E. planum contains mainly flavonoids, especially rutin, while in C. benedictus extracts show the high concentration of the phenolic acids, principally the chlorogenic acid and sinapic acid. Herein, there is the first report of ursolic acid, genistin, and isorhamnetin in E. planum and C. benedictus. C. benedictus polyphenolic-rich extract showed high scavenging activity (IC 50 =0.0081 mg/mL) comparable to that of standard compound (ascorbic acid) and a higher reducing power (IC 50 = 0.082 mg/mL), with IC 50 having a significantly lower value than IC 50 for ascorbic acid. Both extracts were nontoxic to NCTC cell line. Among the investigated herbs, E. planum polyphenolic-rich extract showed the highest inhibitory activities with the IC 50 value of 31.3 μ g/mL for lipoxygenase and 24.6 μ g/mL for hyaluronidase. Both polyphenolic-rich extracts had a higher inhibitory effect on α -amylase and α -glucosidase than that of the acarbose. The synergistic effect of ursolic acid, rutin, chlorogenic acid, rosmarinic acid, genistin, and daidzein identified in polyphenolic-rich extracts could be mainly responsible for the pharmacological potentials of the studied extracts used in managing inflammation and diabetes.
