(Academic Press inc Elsevier Science, 2025) Ercan, Leyla; Akan, Hasan; Caliskan, Cemile Gunbegi
Because of the numerous useful components they contain, plants are significant resources that are being explored for their varied purposes in industry, food, and medicine. Recently, particularly endemic species have gained attention with the identification of their different ingredients and characteristics and the exploration of their precious features. This research assessed the endemic species Astragalus elatus's bioactive components utilizing UHPLC-Orbitrap (R)-HRMS, its antibacterial qualities utilizing the disc diffusion method, its cytotoxic impact on cervical cancer utilizing the MTT method, and its apoptosis effect by annexin V methods. Additionally, Astragalus elatus's antidiabetic activity was revealed by in silico and in vitro examinations of its inhibitory effect on the enzymes alpha-Amylase and alpha-Glucosidase. Consequently, it was discovered that A. elatus can be utilized in the treatment of cervical cancer and has effective cytotoxic and apoptotic effects on HeLa cells. Additionally, it was detected that A. elatus possesses antibacterial and anti-diabetic properties. Compared to gram-negative bacteria, A. elatus had a greater inhibitory effect on gram-positive bacteria. The pharmacokinetically significant characteristics and their tendency for chemical reactions of this plant's primary phenolic compounds were identified by utilizing DFT, molecular docking, and ADME/T.

This study aimed to examine the antibacterial, antioxidant, and enzyme activity of Centaurea hyalolepis, as well as the total phenolic and carotenoid contents, and volatile and phenolic components. Gas chromatography-mass spectrometry was used for the volatile component analysis of C. hyalolepis, while liquid chromatography-mass spectrometry was used for the phenolic component analysis. Furthermore, the antimicrobial activity was evaluated using disc diffusion and microdilution techniques. The antioxidant capacity was investigated in vitro using four distinct methods (2,2-diphenyl-1-picrylhydrazyl, 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid, cupric ion-reducing antioxidant capacity, and N,N-dimethyl-p-phenylene diamine). Additionally, both in vitro and in silico studies were carried out to determine the inhibitory effect on xanthine oxidase and elastase. Consequently, it was determined that C. hyalolepis has antioxidant properties and is a highly efficient antibacterial agent against Bacillus megaterium, Pseudomonas aeruginosa, Bacillus subtilis subsp. spizizenii, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Klebsiella aerogenes, and Candida albicans. Additionally, C. hyalolepis contains many volatile compounds, such as 2-methyl propanoic acid, 3,5-octadien-2-one, 2,6-dimethyl cyclohexanol, hexanal, pentanal, anethole, and beta-cyclocitral. It also has a large number of phenolic components, including chlorogenic acid, apigenin 7-glucuronide, quinic acid, and 4-hydroxybenzoic acid. Moreover, C. hyalolepis was shown to inhibit xanthine oxidase and elastase.
