皖贝母产生物碱内生真菌的筛选与鉴定

Selection and Identification of Producing Alkaloid Endophytic Fungi From Fritillaria anhuiensis

目的:从皖贝母中分离产生物碱的内生真菌。方法:采用组织块法、薄层层析、高效液相色谱-旋转蒸发光检测器法以及形态学和分子生物学方法从皖贝母鳞茎中筛选出产生物碱的内生真菌。结果:从皖贝母中分离出1株产生物碱的内生真菌,并鉴定为极细链格孢菌(Alternaria tenuissima)。结论:从皖贝母中分离到了一株产生物碱内生真菌bm-2,为解决皖贝母药用资源匮乏的问题提供理论依据。

Objective: To select alkaloid-producing endophytic fungi strains from Fritillaria anhuiensis. Methods: The endophytic fungi were selected from the bulbus of Fritillaria anhuiensis, by tissue explants, thin layer chromatography,the high performance liquid chromatography and high performance liquid chromatography-evaporative light scattering detection, morphologic observation and molecular biological methods. Results: One strain as an endophytic fungi capable of producing alkaloid was selected from the bulbus of Fritillaria anhuiensis, and was classified as Alternaria tenuissima.Conclusion: The selected alkaloid-producing endophytic fungi strain bm-2 from Fritillaria anhuiensis provide theoretical foundation for solving the problem of the deficient medical resources of Fritillaria anhuiensis.
