극성이 다른 여러 가지 용매를 사용하여 느릅나무의 뿌리 껍질(이하 유근피)을 추출하였다. MeOH 추출물이 SK-Hep-1에서 분리된 matrix metalloproteinase-9(MMP-9)의 zymography에서 저해능을 나타내었다. 분리 정제한 물질의 분자량은 GC-MS spectrum에서 <TEX>$M^+
Root bark of Ulmus davidiana Plancn. var. japonica Nakai was extracted by using several solvents with different polarities. Each extract was treated on the MMPs obtained from SK-Hep-1 in order to investigate inhibition effect. Zymography of MMPs showed that MeOH extract has significant inhibition effect. On the GC-MS analysis the highest mass to charge ratio (m/z) of the purified substance was 281. Also, on zymography of MMPs the substance showed 47% inhibition effect at the concentration of <TEX>$314.7{\mu}g/g$</TEX>. Cell viability of SK-Hep-1 was 60% at <TEX>$31.47{\mu}g/g$</TEX>.
