Effect of Elicitors on the Production of Valepotriates and Valerenic Acid in the Adventitious Roots of Valeriana fauriei var. dasycarpa Hara

쥐오줌풀 부정근으로부터 valepotriates와 valerenic acid 생산에 미치는 elicitor의 효과

Effects of various concentrations of elicitors for enhancement in valepotriates and valerenic acids production in adventitious root culture of Valeriana fauriei were investigated. Although the growth of adventitious roots was suppresed by addition of biotic or abiotic elicitors, the production of valepotriates and valerenic acids was enhanced. Addition of $100\;{\mu}M$ methyl jasmonate or 1 $g/{\ell}$ yeast extract to the root culture of V. fauriei resulted in the optimal production of valepotriates ($12.56\;{\pm}\;0.78\;mg/{\ell}$) and valerenic acids ($10.63\;{\pm}\;1.1\;mg/{\ell}$), respectively.

쥐오줌풀 부정근으로부터 valepotriates와 valerenic acids 함량을 증진시키고자 다양한 elicitor를 처리하였다. 쥐오줌풀 부정근의 생장은 YE 처리구를 제외한 모든 처리구에서 대조구에 비해 감소하였다. 그러나 valepotriates와 valerenic acids 생산은 모든 처리구에서 대조구에 비해 증가하였으며 특히, valepotriates는 $100\;{\mu}M$ MeJA 처리구에서 $12.56\;{\pm}\;0.78\;mg/{\ell}$, valerenic acids는 1 $g/{\ell}$ YE 처리구에서 $10.63\;{\pm}\;1.1\;mg/{\ell}$ 로 가장 높았으며, 이는 대조구에 비해 1.6배와 1.8배의 생산성증가를 가져왔다.
