Kinetics studies on effects of extraction techniques on bioactive compounds from Vernonia cinerea leaf

Recently, unconventional methods especially microwave-assisted hydrodistillation extraction (MAHE) is being used as an alternative technique for extracting bioactive compounds from plant materials due to its advantages over conventional methods such as Soxhlet extraction (SE). In this study, bioacti...
