Abstract: Disclosed is a method for preparing a red ginseng saponin extract. In the method, saponin components and non-saponin components are extracted from red ginseng and the non-saponin components are selectively removed from the red ginseng extract to prepare a red ginseng extract containing large amounts of the saponin components. According to the method, saponin components are extracted from red ginseng in high yield and non-saponin components are efficiently removed from the extract. Also disclosed is a red ginseng saponin extract prepared by the method. The red ginseng saponin extract is free of precipitable substances and putrefactive substances, such as starch and free sugars, and contains high-purity saponin components at high concentrations. The red ginseng saponin extract is prevented from being discolored and precipitated even after long-term storage, achieving good storage stability and high marketability.
