Abstract

The parts of leaves, flowers and stems in ginseng were obtained for analyzing the component of saponin on 15th April, 25th April, 5th May, 25th May, which were considered as ginseng foliation stage. The total saponin content of the leaves were 97.29, 66.42, 67.61, 36.24 mg/g, respectively, in which the content of Re, $Rb_1$ and Rd were more than 2/3 amount of total saponin. Especially, the saponin content of leaves decreased according to the sequential collection days, in which the similar results were observed from the flowers and stems of ginseng. The total saponin content of the flowers and stems were 141.09,143.84,139.25,133.47 and 13.32, 9.85, 8.00, 4.65 mg/g, respectively. Among them, the content of Re, Rd and $Rb_2$ in flowers were more than 2/3 while the content of Re, $Rg_1$ and Rd in stems showed more than 9/10 amount of total saponin. The total saponin content of individual leaf were 19.46, 28.56, 58.82 and 169.24 mg/plant, 2.53, 2.76, 5.20 and 12.32 mg/plant in stems, and 14.11, 30.21, 37.60 and 73.41 mg/plant in flowers. Therefore, the total saponin content of aboveground parts in ginseng were leaves > flowers > stems.
