New analogues of Sildenafil (Viagra
${\circledR}$ )were identified in the imported Chinese herb drinks, which have been added illegally for affecting penile erectile dysfunction. In order to elucidate the chemical structures of Sildenafil analogues, separation and purification were carried out and followed by analysis of the routine 1D and 2D NMR spectroscopy and FAB mass spectrometry. Based on analytical data one compound was maned as Homosildenafil contains ethylpiperazine switched with methylpiperazine of Sildenafil and the other one was called an Hongdenafil contains ethylpiperazine switched with methylpiperazine and acetyl group instead of sulfonyl group of Sildenafil. As results, Homosildenafil and Hongdenafil were put on the list as new inspection items of the imported food for protectiong public health in Korea. -
2002년 8월부터 11월까지 전국 27개 지역에서 희나리 고추를 포함하고 있는 태양초 시료 40군을 수집하여 총 197주의 곰팡이를 분리하였다. 이 곰팡이들을 고체배지상에서의 번식속도, 분생포자의 모양 및 배양특성의 특성에 따라 6개의 group오로 나누었고 각 group에서 대표가 되는 30 균주를 임의로 선택하여 18S rRNA gene 염기서열을 분석하여 동정하였다. 희나리 곰팡이 중 에서 Colletotrichum 속 곰팡이가 66.5% (131/197)를 차지하여 가장 많이 분리되었고, 기타 Diaporthe phaseolorum var. sojae (28주, 14.2%), Alternaria alternata (17주, 8.6%), Botryosphaeria ribis (9주, 4.6%) Aspergillus oryzae var. oryzae (3주 1.5%) 및 Fusarium incarnatum (9주, 4.6%)이 동정되었다. 각 group에서 임의적으로 한 균주씩을 선택하여 현미에 배양한 뒤 쥐(rat)에 투여시험한 결과 A. alternata를 접종한 사료를 먹인 실험동물이 2주내에 모두 죽었으며 다른 곰팡이를 배양한 사료에는 특이한 영향이 없었다. A. alternata 곰팡이를 현미와 고추즙에 배양하여 주요 독소들을 분석한 결과 17주의 곰팡이 중 8주가 현미와 고추즙에서 많은 양 (현미:
$488{\sim}1572\;{\mu}g/g$ , 고추즙:$115{\sim}1050\;{\mu}g/g$ )의 tenuazonic acid (TeA)를 생성하였다. alternariol(AOH)독소와 alternariol monomethyl ether (AME)는 현미에 배양했을 때만 흔적량 내지 소량씩이 관찰되었다. Alternaria 독소 중 altenuene는 현미와 고추즙 배지 모두에서 검출되지 않았다. -
