Identification of Lignan Compounds in Fruits of Schisandra chinensis BAILLON by Gas Chromatography/Mass Spectrometry

GC/MS에 의한 오미자 Lignan성분의 동정

Eleven lignan compounds in fruits of Schisandra chinensis BAILLON were identified by gas chromatography/mass spectrometry(GC/MS). The GC/MS conditions were as followed: the GC column used was SPB-1 fused silica capillary $(0.25mm\;id{\times}30m,Supelco)$ and the column oven temperature was programmed from $200^{\circ}C$ to $300^{\circ}C$ at the rate of $4^{\circ}C$ per minute; the MS ionization voltage was 70eV (EI mode). The compounds identified were gomisin J $(M^+;\;388)$, deoxyschizandrin$(M^+;\;416)$, gomisin N $(M^+;\;400)$, schizandrin$(M^+;\;432)$, wuweizisu C $(M^+;\;384)$, gomisin A $(M^+;\;416)$, angeloylgomisin H $(M^+;\;500)$, tigloylgomisin H $(M^+;\;500)$, angeloylgomisin Q $(M^+;\;530)$, gomisin B $(M^+;\;514)$ and benzoylgomisin H $(M^+;\;522)$, peaks of which were separated well on the GC chromatogram.

GC/MS를 이용하여 오미자의 chloroform-methanol 추출물로부터 11종의 lignan 성분을 동정하였다. GC column은 SPB-1 fused silica capillary $(0.25mm\;ID{\times}30m,\;Supelco)$를 사용하였고 column oven의 온도는 $200^{\circ}C$부터 $300^{\circ}C$까지 분당 $4^{\circ}C$씩 승온하였으며 MS의 ionization voltage는 70eV (El mode)이었다. 동정된 lignan 성분은 gomisin J, deoxyschizandrin, gomisin N, schizandrin, wuweizisu C, gomisin A, angeloylgomisin H, tigloylgomisin H, angeloylgomisin Q, gomisin B 및 benzoylgomisin H이었으며, GC chromatogram 상에서 이들 화합물의 분리상태는 양호하였다.
