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.

백삼 가공품과 홍삼 가공품의 사포닌 분포 내용과 함량을 비교하기 위하여 시판되고 있는 백삼 농축액(WGC)과 홍삼 농축액(RGC)을 각각 1종 선정하여 조 사포닌의 함량과 개별 ginsenoside의 함량분포를 조사하였다. Shibata의 방법과 우리나라 식품공전에 따라 측정한 조 사포닌의 양은 WGC가 각각 10.65와 21.77%이었으며 RGC는 5.80와 10.94%이였고, HPLC에 의한 총 사포닌의 양은 WGC가 7.40와 10.64%, RGC는 3.31와 3.13%로서 백삼 농축액의 사포닌 함량이 홍삼 농축액의 경우 보다 전반적으로 높았다. HPLC로 분석한 인삼 사포닌, ginsenoside $Rb_1,\;Rb_2,\;Rc,\;Rd,\;Re,\;Rf,\;Rg_1,\;20(S)\;Rg_3,\;20(R)Rg_3,\;20(S)\;Rh_1$ 그리고 $20(R)\;Rh_1$ 이었으며 대부분 홍삼농축액 보다는 백삼농축액의 함량이 높았으며, 특히 ginsenoside $Rb_1,\;Rg_1$ 그리고 $Rb_2$은 백삼 농축액에 3배 이상 더 함유되어 있었다. 또한 protopanaxadiol group과 protopanaxatriol group의 비율(PD/PT)에 있어서는 농축액간의 차이는 크지 않았다. 홍삼의 특유 사포닌으로 알려진 20(S)- 및 20(R)-ginsenoside $Rg_3$가 WGC와 RGC에 비슷하게 분포하는 것으로 확인되었다. 20(S)-ginsenoside $Rg_3$의 조 사포닌 조제법에 따라 RGC에서 0.48과 0.47% WGC에 0.40와 0.53%, 20(R)-ginsenoside $Rg_3$도 RGC에 0.10과 0.11%, WGC에 0.14와 0.22%이었다.
