Analysis of Flavonoids in Acanthopanax by UV-Vis Spectrophotometry with Comparative Study on Different Extraction Technologies

摘要

Acanthopanax Senticosus is a traditional medicinal plant in China. Flavonoids are one of the main active ingredients of this plant. Four extraction technologies of flavonoids from Acanthopanax Senticosus were investigated and compared, including microwave-assisted extraction, ultrasonic extraction, reflux extraction and Soxhlet extraction. The results showed that microwave-assisted extraction was most suitable for the extraction of flavonoids from Acanthopanax Senticosus because of its high effect and short extraction time.
