Abstract

This study was conducted to gather the basic data on making good use of a kind of groundsel (Ligularia fischeri). We have made methanol extracts from Ligularia fischeri and have also determined the effects of extracting temperature and time on the physiological activities of methanol extracts from Ligularia fischeri. Total phenolic compound and flavonoid contents in the methanol extracts from Ligularia fischeri at the extracting concentration of $1,000mg{\cdot}L^{-1}$ were $75.8-297.7mg{\cdot}L^{-1}$ and $45.6-173.6mg{\cdot}L^{-1}$. Total phenolic compound and flavonoid contents, and DPPH radical scavenging activities were most increased when Ligularia fischeri was extracted with methanol at $95^{\circ}C$ for 6 hours, however, nitrite radical scavenging activities were extremely increased at $75^{\circ}C$ for 12 hours by 97.4%. At $200mg{\cdot}L^{-1}$ and $400mg{\cdot}L^{-1}$ methanol extracting concentration, the hyperplasia of lung cancer cells (Calu-6) and stomach cancer cells (SNU601) were effectively inhibited over 90%. Consequently, it was assumed that Ligularia fischeri was a functional vegetable with a higher physiological activities. Making the processed foods, it had better make the extracts from Ligularia fischeri with methanol at $95^{\circ}C$ for 6 hours.

곰취(Ligularia fischeri)의 이용성을 높이데 필요한 기초자료를 확보하고자 메탄올을 용매로 하여 추출 온도 및 시간에 따른 생리활성 효과를 조사하였다. 곰취 메탄올추출물 $1,000mg{\cdot}L^{-1}$에 함유된 총 페놀함량, 총플라보노이드 함량은 각각 $75.8-297.7mg{\cdot}L^{-1}$ and $45.6-173.6mg{\cdot}L^{-1}$이었다. 추출온도와 시간은 총 페놀함량, 총 플라보노이드 함량, 전자공여 능 의 경우 $95^{\circ}C$에서 6시간 동안 추출했을 때 가장 좋았다. 그러나 아질산염 소거능은 $75^{\circ}C$에서 12시간 추출한 것에서 97.4%로 가장 높게 나타났다. 곰취 메탄을 추출물 $200mg{\cdot}L^{-1}$ 및 $400mg{\cdot}L^{-1}$ 농도는 각각 폐암과 위암세포 증식을 90% 이상 억제시켰다. 따라서 곰취는 높은 생리활성 기능을 나타내는 채소로 나타났으며, 곰취를 가공품으로 이용하기 위해 메탄올로 추출할 때는 $95^{\circ}C$에서 6시간 정도 하는 것이 좋을 것으로 생각되었다.
