摘要

Provided is a method for preparing the extracts of Taiwanofungus camphoratus with a capacity for inhibiting the activity of matrix metalloproteinases. This product is obtained from submerged culture for mycelium of the isolated strain of Taiwanofungus camphoratus. Various concentrations of ethanol precipitation with the cultural medium comprising exopolysaccharides have been performed to separate several fractions of polysaccharides with different molecular weights. Especially, this novel mixture containing exopolysaccharides with molecular weights between 1000 and 30000 exhibits the suppressing ability on the activity of matrix metalloproteinases (MMPs). In addition, also provided is an entire process for preparing this product including the procedures for agar plate culture, mycelium culture, and extraction by means of various concentrations of ethanol.
