1H-NMR, 13C-NMR, Dept. NMR의 spectrum으로 compound 1은 safrole로, compoud 2은 o-methyleugenol로 추정(推定)되었으며 처리농도별(處理濃度別) 발아억제(發芽抑制) 효과조사(效果調査)에서 발아억제 물질로 추정한 safrole은 25mg/ml의 처리에서도 발아 및 생육억제 효과를 나타내지 않았다. o-methyleugenol의 경우는 5mg/ml의 처리(處理)로 최종발아(最終發芽)는 무처리구에 비해 58% 저해하였으며, 그리고 25mg/ml에서도 92%, 생육(生育)에는 100%의 저해도(沮害度)를 나타내었다. 이상(以上)의 결과(結果)를 보면 o-methyleugenol은 세신의 강(强)한 발아저해활성 물질의 하나로 처음 확인되었으며 천연(天然) 제초제(除草劑)로서의 개발(開發) 가능성(可能性)은 추후 재검증(再檢證)해 보아야 하겠다.
Treatment of ethylacetate extract of Asiasarum sieboldi inhibited the germination and the growth of radish seeds. Two phenylpropanoids were isolated from ethylacetate extract. Their structures were identified as safrole and o-methyleugenol by spectroscopic evidence. From the test to inhibitory effect, o-methyleugenol had inhibited the germination and the growth of radish seeds, while safrole did not. The germination rate and radicle length of radish seeds were decreased to 63.0%, 31.5 % of control at 5mg/ml of o-methyleugenol, respectively. At the same concentration, o-methyleugenol inhibited the hypocotyl growth up to 100%.
