Ginseng is one of the most important plant drugs which has been used as a medicine in Asia. Main effective components of ginseng have been recently believed to be saponins which have been isolated and identified from Panax ginseng C. A. Meyer. Decrease in total saponin content of white ginseng by storage years was remarkable in contrast with red ginseng. In storage for three years, decrease in red and white ginsengs were 12% and 27% for total saponin content, and 16.8% and 42.2% for major saponin content, respectively. The PT/PD ratios of red and white ginseng saponins were ranged 0.646 to 0.694% and 0.414 to 0.428%, respectively. According to the result of PT/PD ratios, red ginseng was greater than 50% in compare with white ginseng. The change of PT/PD ratio would greatly influence on the biochemical and pharmacological effects of ginseng.
