摘要
目的:测定不同采收月份和年限金钗石斛中石斛碱的含量,探索不同采收月份和年限石斛碱含量变化规律。方法:采用气相色谱法测定不同采收月份和年限金钗石斛中石斛碱的含量。结果:不同采收月份中,9月份石斛碱含量最低,为0.239%,1月份石斛碱含量最高,达0.559%,不同采收年限中,一年生石斛碱含量最高,达0.546%。结论:不同月份、不同年限的金钗石斛中石斛碱均有明显差异,实验为金钗石斛采收期的确定提供评价依据。
Objective：To determine the content of dendrobine in Dendrobium nobil from different collection periods,to discover the inherent rule about the content change owing to different collection periods.Method：Determinate the content of dendrobine in D.nobil from different collection periods by gas chromatography.Result：The content of dendrobine varies in different harvest time,with 0.239% at the lowest point in September and 0.559% at the highest point in January.The dendrobine content of the annuals is 0.546%,which is the largest among that of different harvest years.Conclusion：This offered evidence to determine the most appropriate harvest time for D.nobil.
