Abstract

The invention discloses a novel application of mucuna birdwoodiana extract, namely an application of the mucuna birdwoodiana extract in the preparation of drugs for treating leukemia. The mucuna birdwoodiana extract is prepared by the following steps: taking mucuna birdwoodiana as the raw material, then extracting the raw material by adopting a supercritical carbon dioxide extracting technology, purifying the extract by adopting a macroporous resin purifying technology so as to obtain a mucuna birdwoodiana extract A, a mucuna birdwoodiana extract B, and a mucuna birdwoodiana extract C, and mixing the three extracts according to a certain ratio so as to obtain the mucuna birdwoodiana extract. The mucuna birdwoodiana extract provided by the invention has an important meaning in the preparation of drugs for treating leukemia.

Description

technical field [0001] The invention belongs to the field of medicine and relates to the application of a Chinese medicinal material extract in the preparation of a drug for treating leukemia, in particular to the application of an extract of A. chinensis in the preparation of a drug for treating leukemia. Background technique [0002] Leukemia is a malignant disease of hematopoietic origin and characterized by the production and accumulation of large numbers of immature and abnormal white blood cells in the bone marrow or other hematopoietic tissues. In terms of form, most leukemia cells are immature and morphologically abnormal leukocytes; in function, leukemia cells have the same characteristics as tumor cells: leukemia cells are tumor-proliferating and uncontrollable, often leading to inhibition and failure of bone marrow hematopoietic function. The patient suffers from anemia, neutropenia and thrombocytopenia, and leukemia cells can infiltrate various tissues and organs...
