Relationship among Ginsenosides of Panax ginseng Root under the Variation of Mineral Nutrients

무기영양변화에서 인삼근Ginsenoside의 상호관계

Relationships among ginsenosides, panaxadiol(PD), panaxatriol(PT), and total saponin(TS) in Panax ginseng root (2nd Year) grown with culture solotion different in nitrogen, phosphorus and potassium level were analyzed by simple correlation, multiple regression and standard partial regression coefficient. The closeness between ginsenosides by simple correlation was closely related with the similarity of molecular structure. The content of PT was much attributed to Re and Rg1. The contribution order of ginsenosides for PD was Rb1>Rb2$\geq$Rd>Rc. There was significant positive correlation between PT and PD but PD increased more rapidly than PT. Thus total saponin depended much on PD and PT/PD decreased with the increase of total saponin content. All ginsenosides, especially Re showed decreasing tendency with the increase of root weight.

양분조성(N.P.K)을 달리하여 양액재배한 인삼근(2년생)에서 ginsenoside, triol(PT), diol(PD) 및 총saponin(TS)과의 관계를 단순, 다중회귀 및 standard partial regression coefficient의 검정으로 분석하였다. ginsenoside 상호간의 밀접도는 분자구조의 유이도와 관계가 깊은 것으로 나타났다. PT는 Re와 Rg1에 의존하였으며 PD의 변화는 Rb1>Rb2$\geq$Rd>Rc의 순으로 의존하였다. TS도 PD에 의존도가 커서 TS가 클수록 PT/PD가 적어졌다. PT가 커지면 PD는 더 커지므로 PT와 PT/PD는 부상관을 보였다. 근중이 커지면 모든 ginsenoside는 감소하는 경향이며 Re와는 유의성이 있었다.
