[Objective]To detect the moisture and ash contents in HERBA PLUMBAGINIS ZEYLANICAE under different cultivation conditions,and to provide test data for the establishment of quality standard for HERBA PLUMBAGINIS ZEYLANICAE.[Methods]The moisture and ash contents in HERBA PLUMBAGINIS ZEYLANICAE were detected according to the detection methods in Chinese Pharmacopoeia(appendix IXH and IXK,2005 edition).[Results]As for different reproduction modes,the moisture contents in the roots and stems were8.46%-11.64%and 8.54%-11.73%,respectively.The total ash contents in roots and stems were 18.22%-19.82%and 15.83%-18.64%,respectively.Under different soil environments,the moisture contents in the roots and stems were between 7.48%and 9.29%,and that in leaves was 9.27%to 11.77%.The total ash contents in the roots and stems were 15.56%-32.89%,and that in leaves was 11.61%to 30.13%.Under different fertilizer conditions,the moisture content in roots of HERBA PLUMBAGINIS ZEYLANICAE was between 9.02%and 9.77%,and that in stems was 8.69%-11.15%;the total ashes content in roots was 28.46%-29.23%,and that in stems was26.70%-28.72%.[Conclusions]This method was simple,accurate and repeatable,and provided test data for the establishment of quality standard of HERBA PLUMBAGINIS ZEYLANICAE.
[Objective] To detect the moisture and ash contents in HERBA PLUMBAGINIS ZEYLANICAE under different cultivation conditions, and to provide test data for the establishment of quality standard for HERBA PLUMBAGINIS ZEYLANICAE. [Methods] The moisture and ash contents in HERBA PLUMBAGINIS ZEYLANICAE were detected according to [Results] As for different reproduction modes, the contents of the moisture in the roots and stems were 8.46% -11.64% and 8.54% -11.73%, respectively. The total ash contents in roots and stems were 18.22% -19.82% and 15.83% -18.64%, respectively.Under different soil environments, the contents of the roots and stems were 7.48% and 9.29%, and that in leaves was 9.27 % to 11.77%. The total ash contents in the roots and stems were 15.56% -32.89%, and that in leaves was 11.61% to 30.13% .Under different fertilizer conditions, the moisture content in roots of HERBA PLUMBAGINIS ZEYLANICAE was between 9.02% and 9 .77%, and that in stems was 8.69% -11.15%; the total ashes content in roots was 28.46% -29.23%, and that in stems was 26.70% -28.72%. [Conclusions] This method was simple, accurate and repeatable, and provided test data for the establishment of quality standard of HERBA PLUMBAGINIS ZEYLANICAE.
