Research on the Extraction of Total Flavonoids from LyceumbarbarumL Residue with Microwave Assisted Technique

Objective： The best extraction technique of total flavonoids from LyceumbarbarumL was explored. Method： The orthogonal design was used in the research on the extraction technique of total flavonoids from LyceumbarbarumL with organic solvent assisted with microwave. Results： The optimum conditions on the extraction of total flavonoids from LyceumbarbarumL was as follows： ethanol 96 %, the ratio of solid to liquid 1：12, microwave power 400 W, the return of microwave-assisted 40 min. Achieve wolfberry extract flavonoids yield 62.72 %, total flavonoids from dry extract up to 2.69 %. Conclusion： The technique ensured a high content of flavonoids extracted, which was the optimization extraction measure of total flavonoids from LyceumbarbarumL Residue.
