Abstract: Microwave-assisted dynamic extraction of the total flavonoids, rutin and quercetin from Flos Sophaoae was studied. The dynamic extraction with household microwave oven was applied, and at the same time was compared with Soxhlet extraction and the method of bath extraction with special microwave oven. The results indicated that comparing with Soxhlet extraction this method not only needed a shorter time, but also simplified the procedure, and made higher yield of the extraction, and comparing with bath extraction with special microwave oven, this method have the advantage of cheap, safe and being helpful to investigating the extraction process.

Key words: Microwave-assisted extraction, Soxhlet extration, Total flavonoids, Rutin, Quercetin, Flos Sophaoae
