Abstract

This study was conducted to confirm the application as ingredients of cosmetics through an examination of the function for anti-cancer and anti-microbial of the fraction isolated from Pyrus ussuriensis leaves. The dried leaf of P. ussuriensis were extracted with acetone-$H_{2}O$ (6:4, v/v), concentrated and fractionated with the upper layer of acetone on a separatory funnel. Each fraction was freeze dried, then a portion of acetone soluble powder was chromatographed on a Sephadex LH-20 column using a series of aqueous methanol as eluents and also used the MIC-gel using a series of aqueous methanol as developing solvent. The isolated compounds were identified by silica-gel TLC. The growth inhibition activity was measured using the MTT assay by the mouse meltioma (B16F10) cell. The cancer cell growth inhibition rate of fractions isolated from P. ussuriensis leaf was 80%. In anti-microbial activity test, the fraction of P. ussuriensis with 0.25 mg/disc resulted in the clear zone of 1.3 cm and 2 cm for Staphylococcus aureus and S. epidermidis of gram positive bacillus, respectively. In Escherichia coli of gram negative bacillus, the fraction with 0.5 mg/disc resulted in the clear zone of 1.1 cm~1.5 cm each fraction. From these results, we confirmed that acetate fraction of P. ussuriensis has a great potential as a natural ingredients with a anti-cancer and anti-microbial source.

본 연구는 산돌배나무 잎에서 추출한 분획물의 항암 및 항균효과를 조사하여 화장품소재로 적용 가능성을 확인하기 위하여 수행하였다. 산돌배나무 잎을 채취하여 건조시킨 후 분쇄하여 60% acetone-$H_{2}O$(6:4, v/v)로 추출하고 아세톤 가용부를 분획하여 동결건조 시켰다. 아세톤 및 물 가용부를 Sephadex LH-20으로 충진한 칼럼에서 MeOH을 용출용매로 사용하여 칼럼크로마토그래피를 실시하고 또한 MeOH를 전개용매로 사용한 MIC-gel을 이용했다. 단리된 화합물들은 silica-gel TLC로 확인하였다. 항암효과는 마우스 피부암 세포(B16F10)를 이용한 MTT assay로 측정했다. 산돌배나무 잎으로부터 얻어진 분획물의 암세포 생장 저해율은 80% 이상의 저해률을 보였다. 항균활성 실험에서 산돌배나무 잎의 분획물은 그람양성균인 Staphylococcus aureus, Staphylococcus epidermidis에 대하여 0.25 mg/disc에서 1.3 cm, 2 cm의 생육 저해환을 나타내었다. 그람음성균인 Escherichia coli 에 대하여 0.5 mg/disc에서 각 분획물들은 1.1 cm~1.5 cm의 생육 저해환을 나타내었다. 이상의 결과로 미루어 보아 산돌배나무 잎의 아세톤 분획물은 항암 및 항균효과를 가진 천연소재임을 확인할 수 있었다.
