The individual phenolic components were assessed via ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS). In terms of chemical composition, phenolics (hydroxybenzoic and hydroxycinnamic acids) and flavonoids were identified as main groups. The antioxidant capacities were evaluated using a panoply of cell-free bioassays and the enzymatic inhibitory potentials against key enzymes involved in human diseases were also determined. The water extract exhibited the strongest scavenging abilities on DPPH (IC50: 1.05 mg/mL) and ABTS (IC50: 1.02 mg /mL). The best cholinesterase inhibitory abilities were observed with the methanol extract (IC50: 0.51 and 0.52 mg/mL for AChE and BChE, respectively), while DCM exhibited the strongest α-amylase (IC50: 1.21 mg/mL) and α-glucosidase (IC50: 0.62 mg/mL) inhibitory effects. The anti-cancer effects of methanol and water extracts were tested on human breast cancer cells, MDA-MB-231, and the methanol extract showed the best anti-cancer effect with an IC50 value of 102.4 μg/mL. In conclusion, the experimental data have demonstrated promising pharmacological activities of S. acuta extracts obtained using different solvents, thereby providing a scientific basis for the validation of the traditional medicinal uses of this plant.falseAnti-cancer | Bioactive compounds | Cholinesterase | Radical scavenging | Sida acuta | SolventsArticle10.1016/j.procbio.2021.03.0282-s2.0-85103694487
