Abstract

The invention relates to the technical field of anti-tumor compounds, in particular to a 17 (15 to 16)-trans-abietane diterpenoid compound which is extracted from clerodendrum bracteatum and has an anti-tumor effect, a preparation method, a pharmaceutical composition and application of the 17 (15 to 16)-trans-abietane diterpenoid compound. The 17 (15 to 16)-trans-abietane diterpenoid compound is a natural anti-tumor compound extracted from clerodendrum bracteatum branches, has the biological activity of inhibiting tumor cells, particularly has an obvious cell inhibition effect on human promyelocytic leukemia cells HL-60, has a very great application prospect in preparation of anti-tumor drugs, and has an important effect on improving the medical and economic values of the clerodendrum bracteatum.

Description

technical field [0001] The invention relates to the technical field of anti-tumor compounds, in particular to a 17(15→16)-trans-abietane type diterpene compound with anti-tumor effect, a preparation method, a pharmaceutical composition and an application. Background technique [0002] Daqing is a shrub or small tree, 3 to 4 meters high, and a few can reach 10 meters. It is a plant of the Verbenaceae Daqing. There are 40 species in this genus in my country, most of which are distributed in South China and Southwest China. Among them, it can be used as medicine There are 23 kinds used. According to the records of herbal medicines in the past dynasties and the experience of folk treatment, various plants of this genus have the functions of clearing away heat and detoxification, expelling wind and dampness, promoting blood circulation and dissipating blood stasis, anti-inflammatory and analgesic, etc. , bruises and other diseases. At present, there is no report on the chemical ...
