The saponin yield and its compositional changes of red ginseng extract (RG-EXT) was investigated during extraction at various temperatures for 5 times of 8 hrs. The higher temperature resulted in an increase in solids yield while the total saponin recovered decreased, particularly at 100 deg. C. A relatively lower thermal stability was found for protopanaxadiol saponin, one of the saponin fractions, than protopanaxatriol saponin. The compositional ratio of saponin at ginsenoside level was little affected by extraction time
