不同栽培条件下白花丹药材的水分、灰分含量测定

The determination of moisture and ashes from cultivated herba plumbaginis zeylanicae

目的:测定不同栽培条件下白花丹药材的水分、灰分的含量,为建立白花丹药材质量标准提供实验数据.方法:按《中国药典》2005年版I部附录IXH中水分测定法中的第一法、附录IXK灰分测定法测定.结果:不同繁殖方式的药材水分含量根为8.46～11.64%,茎为8.54～11.73%;药材的总灰分测定结果根为18.22～19.82%之间,茎为15.83～18.64%.不同土壤下生长的药材水分含量根、茎在7.48～9.29%之间,叶为9.27%～11.77%;总灰分含量根、茎在15.56～32.89%之间,叶为11.61%～30.13%.不同肥料环境生长下的药材水分含量根为9.02～9.77%,茎为8.69～11.15%;药材的总灰分测定结果根为28.46～29.23%之间,茎为26.70～28.72%.结论:该方法简单、准确、重复性好,为建立白花丹药材质量标准提供了科学实验数据.

Objective： To determine moisture and ashes from cultivated Herba Plumbaginis Zeylanicae with different cultivated conditions for establishing the quality standards.Method： Samples are determined according to the procedures recorded in the Appendix IXH and IXK of Chinese Pharmacopoeia,published in 2005,for moisture and ashes determination respectively.Results： For different reproductions of Herba Plumbaginis Zeylanicae,the moisture contents of root are between 8.46～11.64 %,and 8.54～11.73 % in stem;The total ashes contents in root are between 18.22～19.82 %,and 15.83～18.64 % in stem.For those grown in different soils of Herba Plumbaginis Zeylanicae,the moisture contents of root and stem are between 7.48～9.29 %,and 9.27 %～11.77 % in leaves;The total ashes contents in root and stem are between 15.56～32.89 %,and 11.61 %～30.13 % in leaves.For those grown in different fertilizers of Herba Plumbaginis Zeylanicae,the moisture contents of root are between 9.02～9.77 %,and 8.69～11.15 % in stem;The total ashes contents in root are between 28.46～29.23 %,and 26.70～28.72 % in stem.Conclusion： The method is simple,accurate,replicate and suitable for the determination of moisture and ashes from Herba Plumbaginis Zeylanicae with different harvested-times for establishing of the quality standards.
