Objective: To study the preparation and quality standards of compound Ginkgo Tongmai capsules. Methods: The active ingredients of Ginkgo biloba L. were extracted with two concentrations of ethanol. A thin layer chromatography method was established. The content of n-butanol extract was used to control the quality of the finished product. Results : The active ingredient of Ginkgo biloba L. was high, the specificity of thin layer chromatography was strong, n-butanol extract was not less than 12mg/grain, RSD was 1.04%, and the reproducibility was good. Conclusion: The preparation process is reasonable, the quality of the obtained preparations is controllable, the properties are stable, and it can meet the needs of clinical drugs.
