To obtain data for the standardization of manufacturing method of red ginseng extract pouch products, saponin and physico-chemical properties of 44 Korean red ginseng extract pouch products were analyzed. The concentration of total ginsenoside contents were 5.5~185.7 ㎎/100 mL. Distribution of the contents of ginsenoside Rg₃, Rg₂, Rh₁, and Rh₂ known to have anticancer effect are as follows: Rg₃ is 1.6~46.3 ㎎/100 mL, Rg₂ is 0~22.0 ㎎/100 mL, Rh₁ is 0~4.3 ㎎/100 mL and that of Rh₂ is 0~20.4 ㎎/100 mL, respectively. The anti-diabetic effect of ginsenoside Rb₂ and Re distribution of contents were 0~10.8 ㎎/100 mL and 0~7.0 ㎎/100 mL, respectively. Among the other saponins, exhibited content to distribution of ginsenoside Rb₁ was 0~25.2 ㎎/100 mL, Rc was 0~12.5 ㎎/100 mL, Rd was 0~11.3 ㎎/100 mL, Rf was 0~5.9 ㎎/100 mL and Rg₁ was 0~4.4 ㎎/100 mL. Results of physicochemical characterization showed total sugar content of 226.6 ~3,102.9 ㎎/100 mL, total soluble solids content 1.4~9.5°Bx, turbidity 82.2~100.0%, pH in the range of 4.1 to 5.0, respectively. In approximately 50% of collected domestic ginseng extract pouch products (21~24 items), ginsenoside Rb₁, Rb₂, Rc, Rd, Re and Rg₁ were not detected, and saponin content of each product appears to differ greatly. Results indicated that standardization of production methods and standards set for red ginseng extract pouch products in Korea is needed.
