燕麦壳渗滤液(Avena sativa L.San)抑制根的伸长，导致根膨胀和大量的根毛形成。采用柱层析和薄层层析系统对活性物质进行分离。高效液相色谱(HPLC)显示3个峰，其中一个峰与相关物质相对应。经紫外光谱、氨基酸分析、核磁共振和质谱仪鉴定为色氨酸。
Leachate of oat hulls (Avena sativa L. cv. Sang) inhibits root elongation and causes swollen roots and abundant root hair formation. The active substance was isolated by column chromatography and thin layer chromatography (TLC) systems. High performance liquid chromatography (HPLC) revealed 3 peaks, one of which corresponded to the substance responsible. The latter was identified as tryptophan by means of its UV spectrum, amino acid analysis, nuclear magnetic resonance spectrometry (NMR) and mass spectrometry (MS).
