Abstract
|
|
|
This study compared the contents of ginseng prosapogenin depending on the extracting conditions of Ginseng Radix
palva(Panax ginseng) to provide basic information for developing Ginseng Radix palva-based functional foods. Our findings show that the content of crude saponin peaked at 18 hours of extraction and when extracted twice at 100oC (GRP-18). However, the content of total saponin reached its height at 6 hours of extraction at 100oC (GRP-6) and when extracted twice. On the other hand, the content of ginsenoside Rg3, Rg5 and Rk1 from Red and Black ginseng reached their heights at 18 hours of extraction, followed by 72 hours and 15 hours of extraction at 100oC. And at 100oC the main prosapogenin of the content of Black ginseng ginsenoside Rg5 and Rk1 reached their heights at 18 hours of extraction, followed by 72 hours and 15 hours of extraction.
