Problems solved by technology

However, the Shexiang Tongxin Dropping Pills use precious medicinal materials, and its production cost is relatively high. The Pharmacopoeia method has already used 40 pills. Continuing to increase the amount of medicine for enrichment and extraction will increase the cost of testing and waste resources.
Therefore, there is still a lack of an accurate, rapid and low-cost method for detecting the total saponins of ginseng stems and leaves in Musk Tongxin Dripping Pills.

Abstract

The invention provides a method for detecting the content of total saponins in ginseng stems and leaves of a compound traditional Chinese medicine. The steps include: (1) preparation of the test sample: adding water to dissolve and then ultrasonically centrifuging to obtain the supernatant, washing with ethyl acetate, separating the water layer and steaming Dry, then reconstitute with water to volume; (2) Preparation of reference substance; (3) Gradient elution; (4) Determination. This method not only effectively solves the problem that the detected content of total saponins in ginseng stems and leaves is lower than the actual content in the pharmacopoeia method, but also is safe and environmentally friendly to operate, effectively shortens the test cycle and reduces costs.

Description

technical field [0001] The invention relates to a method for detecting the content of effective components of a compound traditional Chinese medicine, in particular to a method for detecting the content of total saponins in stems and leaves of ginseng. Background technique [0002] Shexiang Tongxin Dropping Pills are made according to the ancient prescriptions "Zhibaodan" and "Liushen Pills". The king medicine of the prescription is artificial musk and toad venom, which are fragrant and clears the veins, relieves spasms and relieves pain; the ministerial medicine, total saponins of ginseng stems and leaves, salvia miltiorrhiza, nourishes the heart, activates blood and removes blood stasis; the adjuvant medicine, artificial bezoar and bear bile powder, clears the pulse, cools the pulse, resolves phlegm and expels blood stasis; Make the medicine borneol resuscitate and refresh the mind, and directly reach the lesion. The combination of various medicines is aromatic, invigorat...
