Abstract

An alcohol extract of polygonum lapathifolium includes such steps as breaking, reflux extracting in alcohol 2-3 times, collecting filtrate, vacuum concentrating, centrifugal separation to obtain supernatant, extracting in ethyl acetate 2-3 times, collecting liquid extract, vacuum concentrating, silicagel column chromatography and eluting with TLC developer. It can be used for preventing and treating cancer, and treating bacillary dysentery, enteritis, eczema, snake bite, etc.

Description

technical field [0001] The invention relates to a traditional Chinese medicine, in particular to an ethanol extract of Polygonum gossypii (Polygonum gossypii) of the Polygonaceae plant and its preparation method and its use in the preparation and treatment of diseases such as cancer, bacillary dysentery, enteritis, and eczema. application in medicine. Background technique [0002] Malignant tumor is a common and frequently-occurring disease, which has become the number one cause of human death. At present, Western medicines are commonly used in the treatment of malignant tumors. These Western medicines are not only expensive, but also have relatively high toxicity and side effects. The use of Chinese herbal medicines in the treatment or adjuvant treatment of malignant tumors has been a research work. There are many prescriptions in this respect, each with its own characteristics and corresponding curative effects, but a more effective Chinese medicine extract has not been f...
