From the paper

Abstract

The invention discloses a method for extracting and separating the efficacy element, fuscoporine, of medicinal fungi fuscoporia obliqua, which carries out desaltification processing to the fuscoporia obliqua by using a hydrochloric acid solution with the concentration of 0.5 to 2 percent, and then neutralizes the hydrochloric acid. Ethanol, sherwood oil, ethyl acetate, and normal butanol are respectively adopted to carry out step-by-step extraction separation. The extracting and separating method comprises the steps of desaltification processing to the salinity of the fuscoporia obliqua, step-by-step extraction separation by using the organic solvents of 30 to 50 percent of the sherwood oil, 33 to 65 percent of the ethyl acetate and 65 to 90 percent of the normal butanol after extracting the desalted fuscoporia obliqua by using 65 to 95 percent of ethanol solution, and finally obtaining of the fuscoporine with higher purity.
