Abstract

The invention relates to new application of a herba delphinii extract in preparing anticancer drugs. The herba delphinii extract is prepared by: taking herba delphinii as a raw material, firstly extracting volatile oil, then conducting extraction with ethanol of different concentrations, and finally performing extraction with a low concentration hydrochloric acid water solution. The herba delphinii extract provided by the invention is of great significance in preparing anticancer drugs.

Description

technical field [0001] The invention belongs to the field of biomedicine, and relates to the application of an extract of Chinese medicinal materials in the preparation of anticancer drugs, in particular to the application of an extract of delphinium pilosa in the preparation of anticancer drugs. Background technique [0002] According to statistics from the Ministry of Health in February 2010, the number of cancer deaths worldwide reaches 10 million each year. At present, one-quarter of the global population's death is caused by cancer, and it is predicted that if the current trend continues, one-half of the deaths will be due to cancer by 2050. The incidence of malignant cancer in my country is increasing at a rate of 2.5-5% per year, and it has become the culprit that seriously endangers human life. Among various types of cancer, lung cancer, gastric cancer, and liver cancer have higher incidence rates. [0003] Blood vessels are necessary for the formation and function...
