The invention belongs to the technical field of
molecular biology, and relates to a method for screening
traditional Chinese medicine monomers, specifically relating to a method for screening
monomer ingredients which have protective effect for oxidative damages to liver cells from
Chinese traditional medicines by using
mitochondrion index technique. In the invention, mitochondrial function detection is used as the core technology and methods of
cell proliferation detection, mitochondrial
reactive oxygen species generation detection, mitochondrial
membrane potential detection, energy substance ATP in mitochondria detection and
mitochondrial cytochrome C detection are adopted. Mitochondrial function changes are detected after H7702 cells, which are subject to oxidative damages induced by H2O2, are treated by the
traditional Chinese medicine monomers of SalB, protocatechualdehyde,
sodium danshensu,
cordyceps polysaccharose,
cordycepin and cordycepic acid, and the
traditional Chinese medicine monomers, which have protective effect for oxidative damages to liver cells, are screened. The invention further provides applications of the traditional Chinese
medicine monomers screened in preparing drugs for preventing and treating liver diseases such as
fatty liver, viral
hepatic diseases and
liver fibrosis.
