백삼 및 홍삼 농축액의 사포닌 분석

  • Published : 2003.06.01

Abstract

Commercial white and red ginseng concentrates were analysed for total ginsenoside contents, and compositions of ginsenosides $Rb_1,\;Rb_2,\;Rc,\;Re,\;Rf,\;Rg_1,\;20(S)\;Rg_3,\;20(S)\;Rh_1,\;and\;20(R)\;Rh_1$. The content of crude saponin and total ginsenosides of white ginseng concentrates (WGC) were about 2-3 times higher than those of red ginseng concentrates (RGC). HPLC showed that each ginsenoside content was higher in WGC, with those of $Rb_1,\;Rg_1,\;and\;Rb_2$ being over three times higher than that of RGC. 20(S)- and 20(R)-ginsenoside $Rg_3$, specific artifacts found only in red ginseng, were detected both in WGC and RGC by HPLC. differences in the contents of these specific ginsenosides between WGC and RGC were not significant. The contents of 20(S)-ginsenoside $Rg_1$, determined by HPLC were 0.40 and 0.53 in WGC, whereas 0.48% and 0.47%, and those of 20(R)-ginsenoside $Rg_3$, were 0.14 and 0.22% in WGC, and 0.10 and 0.11% in RGC using the methods of shibata and food Code, respectively.
