Abstract: The present disclosure provides a ginkgo biloba ketone ester capsule. The present disclosure further provides a method for preparing ginkgo biloba ketone ester capsule and use thereof. The present disclosure provides a ginkgo biloba ketone ester capsule and a preparation method thereof. Through optimized preparation operations and conditions, a high-quality ginkgo biloba ketone ester capsule can be obtained. Compared with the ginkgo biloba ketone ester capsule prepared by traditional methods, the ginkgo biloba ketone ester capsule of the present disclosure has stable quality and a low unqualified rate. The consistency of different batches of ginkgo biloba ketone ester capsules is good. In particular, the ginkgo biloba ketone ester capsule can effectively control ginkgolic acids, preventing the use of high-ginkgolic-acid raw materials in the ginkgo biloba ketone ester capsules, so as to effectively improve the safety of ginkgo biloba ketone ester capsules.

Abstract: A ginkgo biloba ketone ester capsule is provided, which is prepared by mixing ginkgo biloba ketone ester raw materials and excipients, granulating and filling into capsules. The ginkgo biloba ketone ester capsule, based on a loading weight of each capsule being 0.2 g, meets the following conditions: 1) a content of rutin is less than or equal to 1.60 mg/capsule; 2) a content of quercetin is less than or equal to 0.160 mg/capsule; 3) a content of bilobalide is 1.04-2.08 mg/capsule; 4) a content of ginkgolide J is 0.04-0.20 mg/capsule; 5) a residual content of ethanol is less than or equal to 0.2 mg/capsule; 6) a content of biflavonoids is less than or equal to 0.008 mg/capsule, the biflavonoids include Amentoflavone, Bilobetin, and Ginkgetin; and 7) a content of Genistin is 0, and a content of ginkgolide M is 0.
