초록
치자황색소로부터 미생물에 의해 변환된 색소의 색조차이를 규명하고자 L. plantarum과 S. epidermidis에 의해 변환된 색소를 Amberlite XAD-4 column chromatography로 정제 한 다음 Sephadex LH-20 column의 gel filtration 용출양상과 분리된 색소의 분광학적 특성을 조사 하였다. L. plantarum에 의해 변환된 색소는 crocetin보다 큰 분자크기를 갖고 588 nm에서 홉수극대를 갖는 단일의 청색소를 생성하며, S. epidermidis에 의해 변환된 색소는 L. plantarum에 의해 생성되는 588 nm에 흡수극대를 갖는 청색소와 함께 crocetin 보다 작은 분자크기와, 413 nm에서 흡수극대를 갖는 황색소를 동시에 생성함으로서 청녹색을 띠는 것임이 밝혀졌다.
The Gardenia jasminoides yellow pigment and converted pigments were completely separated by Amberlite XAD-4 column chromatography. These Pigments were gel filtrated on Sephadex LH-20 column chromatography. The characteristics of absorption spectra of eluate and fractionated pigments were investigated. The pigment converted by Lactobacillus plantarum showed a single blue color with an absorption peak at 588 nm and its molecular size was bigger than that of crocetin. The pigment, converted by Staphylococcus epidermidis, Showed blue-green color, which was composed of yellow color with an absorption peak at 418 nm and blue color at 588 nm. Molecular size of the yellow pigment was smaller than crocetin and that of blue color.
