[Objective] To study the differences of total flavone content in Xiangxi Drynaria fortunei among different germplasm resources.[Method] The total flavones and total naringin were extracted from D.fortunei by microwave method.With rutin as standard substance,the content of total flavones in leaf,petiole and rhizome of 8 D.fortunei germplasm resources harvested in Xiangxi was determined by colorimetry.In addition,with naringin as standard substance,the content of total naringin in different parts of D.fortunei was determined by colorimetry.[Result] There was significant difference about the content of total flavones in Xiangxi D.fortunei among different germplasm resources.More specifically,the content of total flavones in Longshan samples was the highest at 13.5%,followed by Wangcun samples at 1.8%,and the least in Baojing samples.Moreover,the content of total naringin in different parts of D.fortunei followed a trend of leaf>rhizome>petiole.[Conclusion] D.fortunei harvested from Longshan County could be used as the original species for artificial cultivation because of the highest content of total flavones.Besides,D.fortunei leaves could be utilized and developed for the highest content of total naringin,aiming at providing experimental foundation for the research on germplasm resources screen and artificial cultivation of D.fortunei.
