Abstract

This study was conducted to investigate allelopathic potential from Korean Lycoris radiata HERB. Two different solvents such as MeOH and water were used for extraction from Lycoris radiata HERB. Both extract showed inhibitory effect on the germination of barnyardgrass and lettuce seeds, indicating that this species contained the biologically active substances. The inhibitory substance extracted from bulbs of this species was identified by GC-MS as lycorenan, a kind of alkaloid.

1. 꽃무릇으로부터 용매를 다르게 하여 잎과 인경의 MeOH와 수용추출물을 bioassay 한 결과, 농도가 5% 및 10%로 증가하였을 때는 전혀 발아되지 않았으며, 1%에서는 근장이 크게 억제되었다. 용매간의 추출효과에는 차이가 없었으나, 상추의 생장에서는 인경추출액이 잎추출액보다 억제효과가 다소 높은 것으로 보였다. 2. 꽃무릇의 인경을 추출하여 UV를 조사하였을 때 Rf 0.49-0.52에서 보인 spot는 GC-MS에 의해 lycoris alkaloid계통의 lycorenan으로 동정되었다.
