Abstract

The invention belongs to the field of traditional Chinese medicine preparation, in particular to a ginkgo leaf drop pill and a preparation method thereof. The invention provides a ginkgo leaf drop pill for reducing blood lipid and a preparation method thereof, aiming at the problems of poor blood lipid regulating effect and low bioavailability of the ginkgo leaf drop pill prepared by the prior method. The preparation method of ginkgo dripping pills comprises the following steps: a, taking dried leaves of ginkgo, adding into ethanol solution, adopting ultrasonic extraction, adopting biofilm filtration, and extracting at least three times; mixing the collected filtrates, concentrating to obtain concentrated solution, and drying to obtain extract; ginkgo leaf drop pill is prepared by adding radix Salviae Miltiorrhizae extract, grape seed oil, tartary buckwheat powder and folium Sophorae Japonicae extract, matrix and p-aminobenzoic acid. As that method of the invention is use together withthe ultrasonic extraction and the biological membrane filtration, the extraction rate of the ginkgo biloba leaves can be improve, a special substrate is selected when preparing the dripping pill, andp-aminobenzoic acid is added, the drug dissolution rate is 10 times faster than that of the traditional method, and the economic benefit is remarkable.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine preparations, and in particular relates to a ginkgo leaf dripping pill and a preparation method thereof.
