Determination of Lignan Compounds in Fruits of Schisandra chinensis BAILLON by Capillary-GC(FID)

Capillary-GC(FID)에 의한 오미자 Lignan 성분의 정량

The determinabilities of several lignan compounds by capillary-GC (F1D) were studied. The lignan compounds used were deoxyschizandrin, gomisin N, schizandrin, wuweizisu C, gomisin A, angeloylgomisin H and tigloylgomisin H which were isolated from fruits of Schisandra chinensis BAILLON and identified with GC/MS(EI, 70eV), 1H-NMR(300MHz) and IR. 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 linearities between concentration and FID response were maintained in $2{\sim}500ppm$ of deoxyschizandrin and wuweizisu C and in $5{\sim}500ppm$ of gomisin N, schizandrin, gomisin A, angeloylgomisin H and tigloylgomisin H. The contents of lignan compounds in fruits of S. chinensis BAILLON produced at Moo-ju area were analyzed by the GC method: the values obtained of schizandrin and gomisin N were 6.5 and 5.9mg/g respectively, and those of gomisin A, wuweizisu C, angeloylgomisin H, deoxyschizandrin and tigloylgomisin H were $0.5{\sim}1.6mg/g$.

무주산 오미자로부터 lignan 화합물인 deoxyschizandrin, gomisin N, schizandrin, gomisin A, wuweizisu C, angeloygomisin H 및 tigloylgomisin H를 분리 동정하고 capillary-GC (FID)를 이용하여 이들 화합물의 정량성을 조사하였다. 이 때 lignan 화합물의 동정에는 GC/MS (Finigan MAT 212; El, 70eV), 1H-NMR (Bruker FT; 300MHz) 및 IR (Perkin Elmer 599B)을 이용하였으며, lignan 화합물의 정량에는 FID 및 integrator(Hewlett-Packard 3393A)가 부착된 GC (Hewlett-Packard 5890A)를 이용하였다. 한편, 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, carrier gas는 $N_2$, 1.0ml/min(split ratio=40 : 1)을 사용하였다. 각 lignan 화합물의 정량 가능농도범위는 deoxyschizandrin과 wuweizisu C가 $2{\sim}500ppm$이었고 gomisin N, schizandrin, gomisin A, angeloylgomisin H 및 tigloygomisin H 가 $5{\sim}500ppm$이었으며 무주산 오미자의 lignan성분 함량은 schizandrin이 6.50mg/g으로 가장 높았고 gomisin N, gomisin A, wuweizisu C, angeloylgomisin H, deoxyschizandrin, tigloylgomisin H의 순으로 낮은 경향이었다.
