The S. horneri dried powder was extracted using, (a) 70% EtOH and then partitioned sequentially with equal volumes of n-hexane, CH2Cl2 (dichloromethane), EtOAc (ethyl acetate), and n-BuOH (n-butanol). (b) Cell viability assay of RAW264.7 cells. (c) The chromatography (HPLC) analysis results of S. horneri 70% EtOH extract and fucosterol as a standard compound. (d) Positive and (e) Negative mode of UPLC-QTOF-HRMS results of S. horneri extract. Data are expressed as means ± SD (n = 3); *p < 0.05 compared with the control group.
