To establish a convenient quantitative method for dammarane glycosides in Korea ginseng, the ginseng roots harvested at the cultivation areas of Ga Pyeong, Geum San and Jeung Pyeong were dried, powered, extracted with methanol and hydrolyzed. The ginseng root obtained at Gang Hwa was divided into three parts: main root, laterial root and cortex, and then these were treated in the same manner as the above. The various hydrolysates thus obtained were subjected to the analysis by an instrument coupled with flame ionization detector. The results showed that panaxadiol contents in the ginsengs of the three different cultivation sites were similar. However, the lateral root of Gang Hwa ginseng was found to contain the largest amount of panaxadiol among the three parts of ginseng. This method of the analysis for panaxadiol in ginseng was found to be one with relative rapidity and ease.
