Evaluation of phytochemical components from ethyl acetate fraction of Vernonia calvoana using gas chromatography-mass spectrometry analysis and its antioxidants activities

Gas chromatography-mass spectrometry (GC-MS) analysis and antioxidants activity of phytochemical constituents from ethyl acetate fraction of Vernonia calvoana (V.C) was evaluated. The fraction was subjected to GC–MS analysis using 5% diphenyl 95% dimethylpolysiloxane (30 m × 0.25 mm ID × 0.25 µm film thickness), the compounds were separated and identified by Turbo gold mass detector. The...
