Abstract

The invention discloses a tetracyclic diterpenoid compound and a preparation method as well as application thereof. The tetracyclic diterpenoid compound is obtained through extractum extracting, organic solvent leaching, column chromatography on silica gel and high pressure liquid chromatography separation by taking Araliadumetorum Hand.-Mazz roots as a material. The compound has a molecular formula of C20H30O3, is named as dumetorumane B, and has the following structural formula as shown in the description. The preparation method means that the tetranuclear diterpenoid is obtained through extractum extracting, organic solvent leaching, column chromatography on silica gel and high pressure liquid chromatography separation by taking the Araliadumetorum Hand.-Mazz roots as the material. The application is application of the tetranuclear diterpenoid to preparation of drugs for preventing and/or treating tumour and to preparation of drugs for preventing and/or treating human lung adenocarcinoma, human acute promyelocytic leukemia or human breast cancer. The tetranuclear diterpenoid has a remarkable inhibiting effect on cell strains of human lung adenocarcinoma, human acute promyelocytic leukemia or human breast cancer, has good antitumor activity indicatively, and can serve as an antitumor activity component or a lead compound.

Description

technical field [0001] The invention belongs to the technical field of extraction of plant active ingredients, and in particular relates to a tetracyclic diterpenoid compound and its preparation method and application. Background technique [0002] At present, the incidence of cancer in the world is severe, and the morbidity and mortality continue to rise. The World Health Organization released a report in February 2014, predicting that global cancer cases will show a rapid growth year by year, from 14 million in 2012 to 19 million in 2025 and 24 million in 2035. Statistics from the organization also show that there are about 3.5 million new cancer cases in China every year, and about 2.5 million people die from it. Therefore, finding effective anticancer drugs has become a top priority. In the research of anticancer drugs, the research and clinical application of chemotherapy drugs have made great progress. Chemically synthesized anticancer drugs, such as metal complex p...
