目的测定太白楤木饮片中水分、灰分含量,并进行薄层定性鉴别,为制定其质量标准提供依据。方法根据(《中国药典》2010年版)附录方法检测太白楤木饮片水分、灰分含量,运用薄层方法进行定性鉴别。结果六批太白楤木饮片水分平均值为7.85%,总灰分平均值为8.59%、酸不溶性灰分平均值为2.74%;薄层鉴别可以检出竹节参皂苷ⅣA。结论实验方法准确可靠,以上检测指标和参数可以为制定太白楤木饮片质量标准提供依据。
Objective To determine the moisture content and ash content of Taibai mulberry Pieces and to qualitatively identify it by TLC, which can provide the basis for the formulation of its quality standard. Methods According to the appendix method of “Chinese Pharmacopoeia” (2010 edition), the water and ash content of Taibai alder were examined and identified by TLC. Results The average water content of the six batches of Taibai alder was 7.85%, the average total ash content was 8.59% and the average value of acid-insoluble ash was 2.74%. Stemsin ⅣA was detected by TLC. Conclusion The experimental method is accurate and reliable. The above indexes and parameters can provide the basis for formulating the quality standard of Taibai alder.
