Problems solved by technology

[0006] With the deepening of people's understanding of motherwort and the advancement of modern science and technology, the research on the effective parts and active ingredients of motherwort has been carried out rapidly, but there are few studies on the sesquiterpene of motherwort
Moreover, the anticoagulant components may be related to the traditional effect of motherwort "invigorating blood", but the research on anticoagulant components is still very lacking

Abstract

The invention provides an application of a terpenoid to preparation of an anticoagulation drug. The terpenoid has a structural formula I which is as shown in the description, wherein R1 represents H, C1-C5 linear alkyl, glycosyl or a formula which is as shown in the description, and R2 is selected from C1-C4 linear alkyl. According to the application of the terpenoid, an ionane type sesquiterpene compound separated and obtained from leonurus for the first time can obviously inhibit the platelet aggregation in vitro and has extension tendencies to prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) and has a certain anticoagulation activity, so that a new choice is provided for the development of natural anti-thrombus drugs.

Description

Contents of the invention [0001] The present invention relates to the use of a terpenoid compound. In particular, it relates to the use of violane compounds in Motherwort and its extraction and purification method. Background technique [0002] Motherwort was first recorded in "Shen Nong's Materia Medica", formerly known as Chiwei, and was listed as top grade. In "Compendium of Materia Medica", it is called "the holy medicine of the blood family". [0003] Motherwort mainly contains alkaloids, diterpenes, flavonoids, iridoid glycosides, phenylpropanol glycosides, volatile oils, peptides and fatty acids, etc. At present, the active researches are mainly alkaloids and diterpenes: [0004] (1) Alkaloids: Mainly include stachydrine, leonurine, leonurin and leonurin, etc. Modern studies have shown that the total alkaloids of Motherwort have a therapeutic effect on cerebral ischemia-reperfusion injury, among which Leonurine can not only protect myocardial cells from ischemic in...
