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.

The present invention relates to a composition for preventing, treating or improving a prostate disease containing Acanthopanax sessiliflorus, Phragmites rhizome, and Pinus densiflora extracts as an active ingredient. According to the present invention, the complex extract of Acanthopanax sessiliflorus, Phragmites rhizome, and Pinus densiflora has an effect of inhibiting the activity of 5α-reductase associated with benign prostatic hyperplasia and has an advantage of having a few or no side effects of reducing a male sexual function by using a synthetic compound in the related art using ingredients derived from natural plants. Further, it is confirmed that in a complex extract obtained by mixing Acanthopanax sessiliflorus, Phragmites rhizome, and Pinus densiflora extracts at a more proper ratio, the 5α-reductase inhibitory activity is significantly excellent.
