Extraction and characterization of bioactive compounds from hibiscus flower via microwave-assisted hydrodistillation (MAHD)

In this study, the influence of several experimental parameters on the Microwave-assisted Hydrodistillation (MAHD) extraction of Hibiscus flower was investigated: extraction time, solvent polarity, sample amount, solvent volume and sample particle size. It was concluded that the most influential var...

It was concluded that the most influential variables were extraction time and solvent polarity. The optimized procedure employed 35 g of ground flowers, 280 mL of methanol and 120 min of extraction.
