Abstract

The present invention relates to a process for preparing an extract from ivy leaves which includes the active ingredient hederacoside C and α-hederin, and to extracts prepared by this process. According to this there is initially provision of a first, α-hederin-rich extract and subsequently provision of a second, hederacoside C-rich extract. In a last step, the two extracts are blended to give an extract which has an adjusted hederacoside C content and an adjusted α-hederin content.
