望江南(茳芒决明)质量标准研究

目的 为控制望江南（茳芒决明）药材的质量,建立望江南（茳芒决明）的显微鉴别、薄层鉴别、和含量测定标准。方法 采用粉末进行显微鉴别;采用TLC法对大黄素甲醚成分进行薄层鉴别;采用HPLC法测定茳芒决明中大黄素甲醚含量,色谱条件：色谱柱为XBridge C18（5μm,4.6 mm×250 mm）,流动相为甲醇-0.1%磷酸溶液（75∶25）,柱温为35℃,流速为1.0 m L/min,检测波长254 nm。结果 粉末的显微特征与文献记载基本一致。薄层鉴别色谱斑点清晰,分离度较好。含量测定中大黄素甲醚在1.942 4--24.28μg/m L之间呈良好线性关系（r=1.0）,平均回收率为100.1%（n=6）。结论 本文采用的方法操作简便,准确,重复性好,可用于控制望江南（茳芒决明）药材的质量。

小儿外用健脾散质量标准研究

目的:提高和完善小儿外用健脾散的质量标准。方法:采用薄层色谱法对方中丁香、肉桂、山柰进行定性鉴别;采用中国药典附录方法对浸出物进行测定;采用HPLC法测定肉桂中桂皮醛的含量,色谱条件:色谱柱为Waters Symmetry C_(18)柱(150mm×4.6mm,3.5μm),流动相为乙腈-水(35∶75),柱温为35℃,流速为1.0mL·min^(-1),检测波长290nm。结果:薄层鉴别色谱斑点清晰,分离度较好。HPLC显示桂皮醛在20.32～254μg范围内呈现良好的线性关系(r=1.0),平均回收率为101.5%,RSD为1.3%(n=6)。结论:该方法操作简便、准确,专属性强,重复性好,可用于小儿外用健脾散的质量控制。

直立百部质量标准研究

目的：为控制直立百部药材的质量，建立直立百部药材的显微鉴别、薄层鉴别、水分、总灰分、酸不溶性灰分、浸出物和含量测定标准。方法：采用横切面及粉末进行显微鉴别；采用TLC法对生物碱类成分进行薄层鉴别；采用中国药典附录方法，对水分、总灰分、酸不溶性灰分、浸出物进行测定；采用HPLC法测定直立百部中原百部碱含量，色谱条件：色谱柱为Phenomenex Gemini C6-phenyl（250 mm×4.6 mm，5 μm），流动相为乙腈-0.1%三乙胺（34：66），柱温为30 ℃，流速为1.0 mL·min-1，检测波长306 nm。结果：横切面及粉末的显微特征与中国药典及文献记载基本一致，唯中柱中韧皮部束与木质部束的个数不同于药典规定。薄层鉴别色谱斑点清晰，分离度较好。含量测定中原百部碱在6.257~156.42 mg·L-1浓度范围内线性关系良好（r=0.9998），平均回收率为100.2%（RSD为1.6%，n=6）。结论：本文采用的方法操作简便，准确，重复性好，可用于控制直立百部药材的质量。

Simultaneous qualitative identification of all medicinal herbs in Zaoren Anshen capsule by thin-layer chromatography

The holistic characterization and quality control of all the medicinal herbs of proprietary Chinese medicines(PCMs)are of great significance to ensure their safety,efficacy,and consistency.Thin-layer chromatography(TLC),a simple and classic approach for qualitatively characterizing and examining quality markers of natural products,has been widely used in the characterization and quality control of traditional Chinese medicines.Zaoren Anshen(ZRAS)capsule,prepared from three medicinal herbs of fried Ziziphi Spinosae Semen,Salvia Miltiorrhiza Radix et Rhizoma,and vinegar-processed Schisandrae Chinensis Fructus,is a famous PCM in China for the treatment of insomnia,amnesia,and dizziness in clinical practice.However,no effective method is available so far for simultaneous identification and examination of all the three medicinal herbs of ZRAS capsule.In the present study,we developed a TLC method via twice-development and visualization by UV light or chromogenic agent,which could be used for simultaneous qualitative identification of all the three medicinal herbs of ZRAS capsule in one plate.Moreover,the sample preparation method was optimized.The developed TLC method was rapid,simple,low-cost,and effective,and thus it could be used for quality control of ZRAS capsule.
