Embodiment 1
[0099] A detection method for a drug preparation for eliminating stagnation and laxative, the steps are as follows:
[0100] Properties: This product is a capsule, the content is light yellow to brown powder; slightly gas, sweet and bitter;
[0101] Identification: (1) Take this product and observe under a microscope: there are many columnar crystals, most of which have been broken, with a diameter of 16-52 μm, and the length of the intact ones is 15-82 μm;
[0102] (2) Take 1g of the content of this product, add methanol 10ml, sonicate for 30 minutes, filter, and the filtrate is concentrated to 1ml, as the test solution; take another 1g of Chuanshegan reference medicinal material, and prepare the reference medicinal material solution in the same way; according to China Pharmacopoeia 2010 edition one appendix VIB thin-layer chromatography test, draw 1 μl of each of the above two solutions, respectively spot on the same polyamide film, use chloroform-butanone-formic acid=3:1:1 ...
