This research was aimed to establish the standard extraction and analytical procedures for examining the chromophoric substance in madder root with the ultimate goal of identifying the dyes in badly faded textiles of archaeological origin. The separation temperature of gas chromatography, pH and other extraction conditions were tested. The results were as follows: The suitable separation temperature for the GC cappillary column was 50∼305$^{\circ}C$, and methanol was a good GC solvent for both standard alizarin and madder extraction. The best extraction of madder was achieved by 90 min soaking in room temperature followed by filtration and the actual heat extraction procedure. The best pH for extracting alizarin was pH 3 and above pH 5 alizarin was not detectible. Only alizarin and no purpurin was found in the extraction of the currently used madder plant.

This research was aimed to investigate and compare the effectiveness of TLC and GC-MS methods in the analysis of chromophoric substances extracted from madder plant. Alizarin and purpurin 0.3% solution were used as comparative standards; madder extraction was prepared by heating the solution of powdered madder at 80℃, pH 1.5, for 90 min. Best elution solvent for TLC in silica gel plate was toluene:ethyl acetate=9:1, which resulted in red and yellow spots from madder extraction each of which showed R/sub f/ values 0.32-0.43 and 0.07-0.11. Although the red spot in particular exhibited similar characteristics as standard purpurin in color, shape, and R/sub f/ values, the result was inconsistent throughout different TLC trials. GC-MS analysis showed only small amount of alizarin and no purpurin in the madder extraction. Other chromophoric substance such as 2-furancarboxaldehyde, 5-(hydroxymethyl)-, anthralin, and danthron were also detected in small amounts. The result indicated that TLC was less sensitive to detecting and identifying the natural dyestuff which is generally constituted with a number of similar but chemically different chromophoric substances.

Dyeability of Indian natural dyestuffs to fabrics was investigated. Indian dyestuffs are more inexpensive than domestic dyestuffs purchased at oriental medicine stores. We studied the dyeability of madder, marigold, and pomegranate imported from India on cotton, silk, and wool fabrics. Dyebaths of a combination ratio of 80:20, 60:40, 50:50, 40:60 and 20:80 of madder and marigold, fabrics with orange colors were dyed. To evaluate the dyeability of dyed fabrics, K/S values, Munsell color values and CIE L, a, b, ${\Delta}E$ were measured. The dyeability of fabrics dyed in dyebaths of pH 4 and pH 7 were higher than pH 10. The dyeability in pH 4 was better than pH 7. Silk fabrics dyed with madder and marigold showed good dyeability and wool fabrics showed good affinity in madder dyebath and fair affinity in marigold dyebath. Cotton fabrics showed fair affinity in a marigold dyebath of pH 4 and pH 7. Cotton fabrics dyed with a 60:40 ratio of madder and marigold showed 4.76YR of Munsell color value. Silk Fabrics dyed with a 40:60 ratio showed 4.76YR and wool fabrics dyed with 20:80 ratio showed 5.57RY. The ratios produced the closest colors to 5.0YR of orange. This result indicated that marigold had a more powerful effect on cotton fabrics while madder was stronger on wool fabrics. Fading grades of washing colorfastness of wool and silk fabrics dyed in mixed dyebaths were higher than 3.5-4.0 and higher than homogeneous dyebaths. Staining grades of washing colorfastness of all dyed fabrics were between grades 3.5-5.0. Colorfastness to dry-cleaning was high as grades 4.0-5.0 in all of dyed fabrics. Colorfastness to light of dyed fabrics showed a fair grade of 3.5-5.0; in addition, wool fabrics showed lower grades than silk and cotton fabrics.

The purpose of this study is to enhance the usability of hanji fabrics by expanding the color space of hanji fabrics. For the expression of various colors of hanji fabrics, single and combination dyeing were carried out using natural indigo(Niram, Polygonum tinctorium), marigold extract colorant, and madder extract colorant for three types of hanji fabrics with different fiber compositions(hanji, hanji/cotton, hanji/silk). The light, medium, and deep colors obtained through individual single dyeing were shown to be PB Munsell colors in the case of indigo dyeing, Y color for marigold dyeing, and R color for madder dyeing. For combination dyeing, indigo dyeing was first carried out under the conditions for light, medium, and deep colors, respectively, and marigold or madder dyeing was performed thereafter. Indigo and marigold combination dyeing produced PB, B, BG, G, and GY Munsell colors and indigo and madder combination dyeing produced PB, P, RP, and R Munsell colors. Overall, the color change of hanji/silk fabric was more diverse than that of hanji fabric and hanji/cotton fabric. In the indigo, marigold, and madder combination dyeing into individual deep colors, blackish PB and P Munsell colors was obtained. Colorfastness to washing, dry cleaning, rubbing, and light were relatively good with above rating 4. Finally, 9 colors excluding YR color out of 10 Munsell color were obtained. We confirmed that the expansion of the color space of Hanji fabrics by the single and combination dyeing with indigo, marigold, and madder.

In this study, improving the wash and rubbing fastness of a natural coloring matter from Madder extract dyed on Tencel nonwoven. The cationic finishing agent(RBP), nonionic finishing agent(HPX) and mordant(PAW) were used to improving the color fastness. The two types(exhaustion and pad-dry-cure) finishing process were investigated with various finishing agent concentration. The color strength, wash and rubbing fastness of Tencel nonwoven dyed with Madder extract have been evaluated by various dye concentration and finishing agent. The exhaustion process treated with the cationic finishing agent(RBP) was effective to improving washing and rubbing fastness.

This research investigated the effect of mordants on the degradation of madder dye in silk when silk was treated by the H2O2/UV condition as a laboratory simulation of burial induced degradation. Alum, iron, and alum/iron composite mordanting methods were applied to silk before dyeing with madder dye. Dye extracted from silk was examined using HPLC-DAD-MS analysis. The abundance of the chromatogram peak at 8.88 min retention time was used as the concentration of alizarin pigment in silk. K/S values, CIE $L^{\ast}a^{\ast}b^{\ast}$ values; in addition, Munsell HVC values were obtained using a spectrocolorimeter. The findings indicated that alizarin degraded most severely in silk mordanted by alum/iron composite mordanting than alum mordanting or iron mordanting. Mordanting with alum alone provided a relatively lower dye fixation at the point of dyeing; however, it provided a better survival of alizarin after 12 hours of degradation treatment.

The purpose of this investigation was to investigate the degradation products of the dye component extracted from madder dyed fabrics using the GC-MS analysis and to evaluate the change of color due to degradation treatment. Four different degradation protocols were used in this study,; refrigeration at $7^{\circ}C$ (LT), room temperature (RT), oven treatment at $100^{\circ}C$ (OV), and $H_2O_2/UV(PER)$ method. Degradation times for each thermal system were 6 hour, 24 hour, 48 hour, 1 week, 2 week, 4 week. Alizarin was detected from the control and degraded samples of both alizarin dyed and madder dyed fabrics. Benzoic acid, 2, 4-di-tert-butylphenol, phthalic anhydride were detected as the degradation products for both alizarin dyed and madder dyed fabrics. The result suggest that these products can be used as the fingerprints of GC-MS analysis for the identification of madder dye in archaeological textiles. Both alizarin dyed and madder dyed samples became less red and less yellow after degradation. In the PER degradation system madder dyed sample showed the greatest color difference even after 1 week of degradation treatment. Further research is necessary for investigating the color change in the exhumed textiles, which is caused by the dual action of dye fading and the staining of organic matters in the soil.

Indigotin, indirubin, berberine, palmatine, alizarin, and purpurin are major pigments of indigo plant, Phellodendron bark, and madder. The six pigments were examined using the HPLC-DAD-MS instrument for the purpose of the simultaneous detection of the pigments in a single sample run. The HPLC-DAD-MS method examined the individual pigment solutions in DMSO, a solution containing 6 pigments, and the DMSO extract of the silk dyed with a dye solution of 5 pigments excluding indirubin. The retention times of the HPLC chromatograms, ${\lambda}_{max}$ of the uv-vis absorption bands in the DAD analyses, and the molecular ions detected for the compound peaks in the MSD analyses were consistent throughout the analyses of individual pigment solutions, mixed pigment solutions, and dye extracted from silk dyeing. The developed instrumental method of the simultaneous detection of six pigments can identify dye in an exhumed textile if the textile is dyed using any one (or multiple) pigments of indigo, Phellodendron bark, or madder plant.

An efficient protocol for cryopreservation of madder hairy root cultures has been developed using droplet-vitrification. In previous study, combining loading solution C4 (35% PVS3) and vitrification solution B5 (80% PVS3) was the most effective method. In this study, we tried three types of vitrification solution, B5, A3 (90% PVS2, on ice), and A5 (70% PVS2, on ice). Combining loading solution C4 and vitrification solution A5 (on ice) showed the best regeneration rate in this study. Histological changes of the cells within the hairy root of madder were also observed in different steps. The cells from the hairy roots of the control treatment were full and intact with different size of vacuoles and obvious cell nucleus having a dark nucleolus. After the stage of preparing for cryopreservation (after preculturing, loading, followed by dehydration solution A5 or B5), intercellular spaces had become distinct, and within cells, the cytoplasms had become denser and week plasmolyses had appeared. The cell plasmolyses were much more apparent and we measured the degree of plasmolysis by calculating, the area of cell/the area of cytoplasm. The value of plasmolysis degree was the highest in the combination of preculture, loading solution C4, and dehydration solution A5, 1.97. Because the highest regeneration rates appeared in the treatment of A5 for 20 min, we could assume that the optimal degree of plasmolysis for cryopreservation might be around 1.97. The changes in cell structure during cryopreservation might be a useful basis for the development of a proper long-term preservation method for madder germplasms.

This study examined non-destructive UV-Vis spectrophotometry as well as 3-D fluorescence spectrophotometry of textile that made use of red dye such as Sappan wood, madder, Safflower, Gromwell. The authors produced two textile specimen that were dyed by not only two kinds of textile (cotton and silk) but also three kinds of mordanting (no-mordanting, alumen and iron), and they investigated effects of each dye material upon investigation results. At analysis with UV-Vis spectrophotometry of dyed textile specimen, dyeing made by sappan wood, madder and gromwell had significant difference depending upon mardant regardless of kinds of textile, and safflower had no significant difference depending upon textile and mordant. At analysis with 3D-fluorescence spectrophotometry, specimen dyed with sappan wood had difference with mordants, and with madder, there were difference with textiles, and safflower had inherent fluorescence spectrum regardless of textiles and mordants, while gromwell had no fluorescence spectrum.
