Abstract

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.
