FIELD: biotechnology, biochemistry, natural compounds.
SUBSTANCE: invention relates to a method for preparing derivatives of steroid glycosides from the plant Ruscus aculeatus (ruscosaponins). Method for preparing desglucodesrhamnoruscin involves hydrolysis of steroid glycosides from Ruscus aculeatus (ruscosaponins) by fermentation of substrate containing indicated glycosides using fungus of species Aspergillus niger. Method provides preparing desglucodesrhamnoruscin with the high degree of effectiveness.
EFFECT: improved preparing method.
