Abstract

The invention relates to the field of medicine, in particular to application of one or more ginkgo terpene lactone compounds or pharmacologically acceptable salts, esters, hydrates, solvates and isomers of the ginkgo terpene lactone compounds or any crystal forms, racemic mixtures and metabolites of the ginkgo terpene lactone compounds or a mixture of the ginkgo terpene lactone compounds being used as effective components to preparation of drugs and health care products for preventing and / or treating tremor. The problem of the lack of the drugs for preventing and / or treating the tremor in an existing medicine field is solved. The ginkgo terpene lactone compounds and compositions both obviously improve the state of an illness of an essential tremor model mouse, and the improvement action ofa ginkgo terpene lactone B and bilobalide composition and a bilobalide A, bilobalide B and bilobalide C composition on the essential tremor model mouse is close to that of a positive drug propranololhydrochloride. The state of the illness of essential tremor patients and vascular tremor patients is obviously improved, and no adverse reaction is found in clinical observation cases.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the use of ginkgolides in the preparation of medicines and health products for preventing and / or treating tremors. Background technique [0002] Modern studies have shown that the main active ingredients in Ginkgo biloba are flavonoids and ginkgolides. Ginkgo flavonoids include flavonol glycosides, biflavonoids, and catechins. Ginkgolide compounds include Ginkgolide A, Ginkgolide B, Ginkgolide C, Ginkgolide J, Ginkgolide M, Ginkgolide K, Ginkgolide L, Ginkgolide N, and Ginkgolide P , Ginkgolide Q and bilobalide. The research results show that the isolated ginkgolide compounds are similar in structure. The difference between ginkgolide A, ginkgolide B, ginkgolide C and ginkgolide M is the 1, 3, and 7 of the molecular skeleton. Whether the position carbon has a hydroxyl functional group; Ginkgolide L, Ginkgolide K, and Ginkgolide N are obtained by removing a molecule of water from Ginkgo...
