Abstract: The technology of Extraction flavonoids from stems of Huperzia serrata (Thunb.) Trev by microwave was studiedin this paper. The results showed that factors influencing extraction flavoids were in the order as follows: concentration of ethanol>microwave power>irradiation time>rate of material to solvent. The extraction rate was 16.651mg/g under the optimalextraction conditions: ethanol 90%, material: ethanol (W:V) as 1:50, irradiation time 30s and microwave power 650W.

Key words: Huperzia serrata (Thunb.) Trev., flavonoids, microwave, extraction technology
