Abstract

The invention discloses a jatropha curcas alkane type diterpenoid compound, a preparation method and application thereof, and belongs to the technical field of medicines. The preparation method comprises the following steps: firstly extracting euphorbia helioscopia by using an ethanol aqueous solution to obtain a crude extract, and then sequentially carrying out extraction, ODS chromatographic column and HPLC chromatographic multi-stage separation to obtain the jatropha curcas alkane type diterpenoid compound. According to the invention, the preparation method of the jatropha curcas alkane type diterpenoid compound is simple, easy to operate, convenient for industrial large-scale production, and suitable for industrial large-scale production of the jatropha curcas alkane type diterpenoid compound; and the jatropha curcas alkane type diterpenoid compound prepared by the invention has obvious cytotoxicity to a drug-resistant cell line A549/Taxol, and is expected to be used as a potential drug for treating drug-resistant lung cancer.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to jatrophane diterpenoids in lacquer and its preparation method and application. Background technique [0002] Zeqi, also known as Wuduoyun, Wudengcao, Wufengcao, etc., is a plant of Euphorbia helioscopia L. in the family Euphorbiaceae (Euphorbiaceae). The whole plant is used as medicine, and it is distributed in the whole country except Xinjiang and Tibet. everywhere. Zeqi has always been used as a folk herbal medicine. It tastes bitter, slightly cold in nature, poisonous, and returns to the lung, small intestine, and large intestine meridian. According to the records of "Compendium of Materia Medica", it has the effects of diuresis, swelling, phlegm and fever, stagnation and insecticide. It is clinically used to treat ascites, edema, tuberculosis, phlegm, cough and asthma, and it is also used to treat cervical cancer, esophageal cancer, etc., and has certain curati...
