Abstract:

Microwave-assisted extraction of flavonoids from Gynstemma pentaphyllum was explored by single factor and orthogonal experiments. The optimal extraction processing parameters were 30% ethanol as solvent, material-liquid ratio of 1:32 (g/mL), and microwave treatment time of 15 min. Under the optimal extraction conditions, the extraction rate of flavonoids from Gynstemma pentaphyllum was 4.18%. Compared with traditional extraction method, microwave-assisted extraction can shorten extraction time and improve the extraction rate of flavonoids from Gynstemma pentaphyllum.

Key words: Gynstemma pentaphyllum, flavonoids, microwave-assisted extraction, processing technology
