Abstract

The invention belongs to the field of medicaments and particularly relates to inoscavin A as a monomeric component in the phellinus as well as a preparation method and an application of the inoscavin A. The preparation method of the inoscavin A comprises the following steps of: (1) grinding the phellinus serving as a herbal medicine, and carrying out reflux extraction by ethanol; (2) extracting the ethanol extract by petroleum ether, and removing the petroleum ether; (3) extracting the extract by methylene dichloride, taking the ethylene dichloride layer, and drying to obtain the methylene dichloride extract; and (4) dissolving the extract into a flowing phase, carrying out high-speed counter-current chromatography, receiving and merging the flows, and recovering the solvent to obtain dried powder. Due to the adoption of the technical scheme, the compound of the inoscavin A as a monomeric component in the phellinus can be prepared in batch. The experiments in vitro prove that the compound has lung cancer tumor cell inhibition activity and liver cancer tumor cell proliferation activity. The experiments in vivo prove that the compound has the efficacy of diminishing inflammation and regulating immunity and can take effect together with the medicament for tumor chemotherapy so that the medicinal effect of the compound in vitro and vivo can be studied further.

Description

technical field [0001] The invention relates to a kind of monomer component extracted from Phellinus Phellinus, which belongs to the field of medicine: celloporin A (inoscavin A) And its preparation method and application. Background technique [0002] Cancer is the second leading cause of death in humans after cardiovascular disease, posing a serious threat to human health. It is estimated that by 2030, there will be about 21 million new cancer patients worldwide, and about 13.2 million deaths. There are about 2.2 million new cancer cases and 1.6 million deaths in my country every year. Therefore, the prevention and research of malignant tumors has become a research field that medical workers around the world pay close attention to. [0003] Chinese medicine treatment of cancer, because of its multi-target, multi-link and multi-effect characteristics, can improve the body's immunity and play an important role in prolonging the survival period and improving the quality of ...
