Sage (Salvia Macrochlamys): Lc-Hrms for Phytochemical Analysis, Cytotoxicity, Enzyme Inhibition, Antioxidant Activity, Molecular Docking and Molecular Dynamics Simulations

Abstract

This study primarily aims to evaluate the phenolic content and biological activity of Salvia macrochlamys both in vitro and in silico. The antioxidant activities of Salvia macrochlamys were assessed using various methods. Additionally, cytotoxic effects and the alpha-amylase, alpha-glucosidase, and acetylcholinesterase (AChE) enzyme inhibitory abilities of ethanolic extract of the aerial parts of Salvia macrochlamys (EESM) were evaluated. Then, the molecular docking interactions and molecular dynamic calculations of EESM against alpha-amylase, alpha-glycosidase, and AChE enzymes were carried out. High antioxidant activity was determined in both ethanol and water extracts. The IC50 values of EESM against AChE (EC 3.1.1.7), alpha-glycosidase (E.C.3.2.1.20), and alpha-amylase (E.C.3.2.1.1) were determined as 1.622 mu g/mL, 0.530 mu g/mL, and 1.320 mu g/mL, respectively. High enzyme-inhibiting properties of EESM were determined in also in silico. Rosmarinic acid was identified as one of the most abundant phenolic compounds in both EESM and water extract of the aerial parts of Salvia macrochlamys (WESM) (3919.65 mg/kg and 10520.77 mg/kg, respectively). Their high level of flavonoids and phenolics, as well as the potent antioxidant and enzyme-inhibitory properties displayed by extracts, may contribute to broadening the use of Salvia macrochlamys in both traditional and modern therapeutic applications.
