Method for producing xanthoceraside

The invention relates to the field of development and utilization of shiny-leaved yellowhorn and discloses a method for extracting xanthoceraside from shells, fruit stems and/or flowers of the shiny-leaved yellowhorn. The method provided by the invention comprises the following steps of: firstly, selecting dry and mildew-free shells, fruit stems and/or flowers of the shiny-leaved yellowhorn; crushing until the granularity is 20-40 meshes; extracting by utilizing alcohols with the volume percentage concentration of 50-95% or water to obtain an extracting solution; processing the extracting solution extracted with the alcohols by a macroporous resin or concentrating the extracting solution extracted by water and then processing the concentrated solution by the macroporous resin to remove sugar and pectin; enriching effective components and carrying out a gradient elution on the resin column through utilizing the ethanol with the volume percentage concentration of 20-95% and de-coloring the eluent; respectively
