Gas chromatogram of standardized samples for 10 different kinds of polyghenol components, which contained universally in common vegetables and fruits, and those of polyphenol extracts from various ginseng products and Acanthopanax, were revealed, respectively.
The consequent results are as follows;
1. There were practically no obvious difference in the polyphenol pattern among white ginseng with skin of either Korean, American, Canadian products, or Korean red ginseng. There was, however, no coincidence in to as indicated by peaks of polyphenol pattern for these ginseng products with those expressed by the standard samples.
2. A great similarity existed in the polyphenol pattern between white ginseng and red ginseng extracts, but the number of peaks for the ginseng extracts was far less than dried ginseng.
3. The polyphenol patterns of Russian and Korean Acanthopanax showed a similarity. However, the polyphenol pattern as represented by Acanthopanax was considerably different from that of ginseng products, especially chlorogenic acid which was not present in the ginseng products was identified in Acanthopanax.
