Problems solved by technology

However, in this content determination method, the conventional traditional Chinese medicine quality control mode is still used, that is, jujube seed saponin A, B or spinosin reference substance is used as a contrast, and the quality evaluation analysis of jujube seed is carried out. The evaluation index of this mode Relatively single, overly dependent on traditional Chinese medicine chemical reference substances, not environmentally friendly, and high testing costs

Abstract

The invention relates to spina date seed reference extract and a preparation method and application thereof and belongs to the technical field of traditional Chinese medicine quality control. The preparation method of the spina date seed reference extract includes the following steps of smashing, degreasing, extracting, macroporous resin purifying, silica gel purifying and acquiring of the spina date seed reference extract finally. Spina date seed medicinal materials are degreased, extracted and purified through a specific method, finally the spina date seed reference extract with specific constituents is acquired, and the reference extract includes jujuboside A, jujuboside B and other saponin constituents and further includes spinosin, 6'''-ferula asafetida spinosin and other flavonoid constituents. The spina date seed reference extract serves as a reference to be used in quality control over a traditional Chinese medicine preparation containing spina date seed medicine flavor and has the advantage that constituent information is comprehensively fed back; when the spina date seed reference extract is used, the complex pretreatment step is not needed, inspection can be directly conducted after dissolution, and the advantages of being easy and convenient to operate and low in detection cost are achieved.
