不同采收期和不同部位茵陈药材滨蒿内酯的含量测定与资源利用建议

Determination of Scoparone in Different Parts and Harvest Time of Scoparia and Rational Utilization of Its Resources

目的 为茵陈药材的质量控制、合理采收与资源进一步开发利用提供新的依据。方法 采用高效液相色谱法考察了不同时期、不同部位茵陈药材的滨蒿内酯含量。结果和结论 不同时期、不同部位茵陈药材滨蒿内酯含量差异明显:花期>花前期;带花枝梢>枝干。为此,我们建议:采收茵陈蒿时,最佳时期为9月中上旬;建议《中国药典》将绵茵陈和茵陈蒿区分,作为不同的2种药材处理,并将滨蒿内酯作为鉴别和控制茵陈蒿药材质量的重要指标;从有效性以及野生资源可持续利用等角度考虑,建议在全国推广使用茵陈蒿。

Aim To supply some new references for the quality c o ntrol of Scoparia(Yin Chen), optimization of its harvest time and farther exploi tation of its resource.Method The contents of scoparone were de termined by HPLC in different medicinal parts of Scoparia collected in different times.Results and conclusion It shows that there is a signific ant differentiation in the contents of scoparone in the above Scoparia samples d escribed in this article.Accordingly, It was suggested that the first ten days o f September is the best time to harvest Scoparia(Yin Chen); Scoparia (Yin Chen) could be treated as two different kind of Chinese durgs, Mian Yin Chen (Scoparia harvested in Spring ) and Yin Chen Hao (Scoparia harvested in Autumn); Scoparon e could be considered as a useful quality control standard for Scoparia(Yin Chen );Yin Chen Hao (Scoparia harvested in Autumn) should be used widely in China.
