Abstract:

Objective: To optimize extraction technology of total flavonoids from the root bark of Acanthopanan trifoliatus. Methods: Total flavonoids were extracted from the root bark of Acanthopanan trifoliatus through a microwave-assisted technique. Effects of operation conditions, such as ethanol content, microwave radiation time, power of microwave oven and the ratio of sample weight to solvent volume were studied by using single factor and orthogonal test. Results: The highest extraction yield can be obtained when extraction solvent is 50% ethanol, power of microwave oven is 320 W, microwave radiation time is 30 seconds and the ratio of sample weight to solvent volume is 1:20. Conclusion: Under the optimized conditions, the extraction percent of total flavonoids from root bark of Acanthopanan trifoliatus is 30.04 mg/g.

Key words: Acanthopanan trifoliatus, total flavonoids, microwave-assisted extraction, orthogonal test
