Abstract

The invention relates to the technical field of anti-tumor compounds, in particular to an abietane type diterpenoid compound with an anti-tumor effect, a preparation method, a pharmaceutical composition and application, the chemical name of the abietane type diterpenoid compound is 12, 16-epoxy-17 (15-16)-trans-3, 5, 8, 12-abietane tetraene-7, 11, 14-triketone. The compound is extracted from air-dried branches of the clerodendranthus bracteatus, has an inhibition effect on various tumor cells, particularly has an obvious inhibition effect on human lung cancer cells A549, has a very great application prospect in preparation of antitumor drugs, and has great significance in improvement of medical and economic values of the clerodendranthus bracteatus. The method plays an important role in research on the nutritional value, potential toxicity, biological and pharmaceutical characteristics, chemical components and the like of Clerodendrum bracteatum.

Description

Technical field [0001] The present invention relates to the field of anti-tumor compounds, and more particularly to a rosin-type diiterpene compound, preparation method, and a pharmaceutical composition and application of anti-tumor. Background technique [0002] The Daqing is a bush or a small trembard, high of 3 to 4 meters, a few can reach 10 meters, which is a green plants in the Mawen Bacteria, which is 40 kinds of my country, most of which are distributed in China, Southwest, which is available There are 23 kinds of use. From the experience of the record and folk treatment of the past, there are various plants to clear the heat and detoxification, the wind dehumidification, the blood circulation, anti-inflammatory analgesia, etc., often used in the treatment of 痈, 疔疔, cold, rheumatoid arthritis Diseases such as anti-injury. At present, the study of the chemical composition of the bossa Daqing has not been reported that the study of the bossa Daqing and its extraction ingred...
