Background : Malonyl ginsenoside content of the Panax ginseng is known to account for 35% to 60% of total ginsenosides content. However, its distribution by ginseng part has not been studied. In this study, four kinds of malonyl ginsenosides were compared in Korean white ginseng part using the purified malonyl ginsenoside standards in our laboratory. Methods and Results : White ginseng was prepared by the air drying (50℃, 48h) or freeze drying (-70℃, 48h) methods form 4-year-old ginseng. Malonyl ginsenoside content in total ginsenosides were similar in air dried and freeze dried white ginseng, 58% and 62%, respectively. Therefore, malonyl ginsenoside contents in main, lateral, and fine root, and in the main root without skin and skin of main root prepared by freeze dried method were compared. Malonyl ginsenosides (m-Rb1, m-Rb2, m-Rc and m-Rd) and total ginsenosides (Rg1, Re, Rf, Rb1, Rc, Rb2, Rb3, Rd, m-Rb1, m-Rb2, m-Rc and m-Rd) were 6.75 and 14.15 mg/g in main root, 14.15 and 26.35 mg/g in lateral root, 46.95 and 84.15 mg/g in fine root. Malonyl ginsenoside contents in skin of main root was 20.08 mg/g, while its contents of the main root without skin was 2.58 mg/g. Conclusion : As a result, the parts each air drying the sample was confirmed that the ratio of the distribution of malonyl ginsenoside (main root : lateral : fine root = 18.7 : 11.1 : 16.2), and distribution ratio of main root, skin of main root, lateral, skin of lateral was found to be (12.2: 14.6 14.3: 3.7). Malonyl ginsenoside content was the highest in fine root, compared to the main or lateral root. Malonyl ginsenoside contents in skin of root was higher than those of the main root without skin. These results is expected to help establish an efficient extraction and standardization. Malonyl ginsenoside analysis of White ginseng using HPLC expects that the standardization process can be established.
