Abstract

Malonyl ginsenoside content of the Panax ginseng C.A. Meyer 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. White ginseng was prepared by the freeze drying ($-70^{\circ}C$, 48 h) or air drying ($50^{\circ}C$, 48 h) methods form 4-year-old ginseng. Malonyl ginsenoside content of main, lateral, and fine root, and of the main root without skin and its skin was compared. Malonyl ginsenosides (m-Rb1, m-Rb2, m-Rc and m-Rd) content (58%, 19.17 mg/g) in total ginsenosides of air dried white ginseng was decreased about 4% compared to its content of freeze dried white ginseng (62%, 20.40 mg/g). Malonyl ginsenoside content was the highest in fine root, compared to the main or lateral root. Malonyl ginsenosides content in skin of main root was 20.08 mg/g, while its content of the main root without skin was 2.58 mg/g. These results are expected to help establishment of quality specification and processing process in Korean white ginseng.
