Two-level factorial screening of microwave-assisted extraction parameters for the recovery of phenolic compounds from vernonia cinerea leaf

Vernonia cinerea is one of the medicinal plants with several potentials for treating different alment. In the present study. Microwave-assisted extraction (MAE) was employed in extracting phenolic compounds from this plant. However, different factors that affect this extraction method in the recover...
