“…Many different analytical methodologies have been utilised for the identification of dyes in cultural heritage materials (Degano et al 2009). High-performance liquid chromatography with diode array UV-visible spectroscopy (DAD) and/or electrospray mass spectrometry (ESI-MS) detection are the most widely applied methods (Karapanagiotis and Chryssoulakis 2005;Surowiec, Szostek and Trojanowicz 2007;Lech, Połeć-Pawlak and Jarosz 2009;Zhang and Laursen 2009;Mantzouris et al 2011;Wouters, Grzywacz and Claro 2011).…”

Among prehistoric native groups of North America, the Ohio Hopewell was a particularly notable cultural manifestation that prevailed during the Middle Woodland Period (ca. 2100 -1500 BP). The group is defined by the construction of elaborate burial mounds, evidence of ritual burning and cremation ceremonies, The presence of anthraquinones in these Ohio Hopewell textiles, and the absence of the bloodroot alkaloids, supports previous studies suggesting the prehistoric use of Galium species as dye plants in Eastern North America.Statement of significance Among the prehistoric native groups of North America, the Hopewell cultural manifestation are particularly notable for their elaborate ceremonial mounds, and the intricately decorated objects they made. While few textiles have survived, those fragments which remain provide important evidence for the technological knowledge and craftsmanship of the people of the past. A rapid method that requires a very small sample yields information about the red dye colorants employed in this fabrics. Direct analysis in real time-time-of-flight mass spectrometry (DART-MS) was used to examine fibers from red-and yellow-coloured textiles from the Seip Mound Group in Ohio, USA. The analysis showed that compounds characteristic of bedstraw plants of the Galium genus, rather than those from bloodroot, provide the red colour.This supports previous work suggesting the use of bedstraw for dyeing in prehistoric Eastern North America.

“…Micro-destructive analytical techniques such as high performance liquid chromatography coupled with diode array or mass spectrometric detectors (HPLC-DAD-MS) are the most suitable set-ups for dyes characterization because of their high sensitivity and selectivity, good chromatographic efficiency, and possibility to achieve quantitative detection [1]. Nevertheless, liquid extraction and separation of the chromophorecontaining molecules from the matrix must be achieved before their analysis.…”

“…Their easy availability in nature and great resistance to photo-oxidation are plausible explanations for their employment since ancient times [1]. Owing to the solubility of these organic compounds in water and in other binding media, they have to be either precipitated as metal complexes or adsorbed on an inert substrate for painting purposes.…”

Abstract. This study deals with the identification of anthraquinoid molecular markers in standard dyes, reference lakes, and paint model systems using a micro-invasive and nondestructive technique such as matrix-assisted laser desorption/ionization time-of-flight-mass spectrometry (MALDI-ToF-MS). Red anthraquinoid lakes, such as madder lake, carmine lake, and Indian lac, have been the most widely used for painting purposes since ancient times. From an analytical point of view, identifying lakes in paint samples is challenging and developing methods that maximize the information achievable minimizing the amount of sample needed is of paramount importance. The employed method was tested on less than 0.5 mg of reference samples and required a minimal sample preparation, entailing a hydrofluoric acid extraction. The method is fast and versatile because of the possibility to re-analyze the same sample (once it has been spotted on the steel plate), testing both positive and negative modes in a few minutes. The MALDI mass spectra collected in the two analysis modes were studied and compared with LDI and simulated mass spectra in order to highlight the peculiar behavior of the anthraquinones in the MALDI process. Both ionization modes were assessed for each species. The effect of the different paint binders on dye identification was also evaluated through the analyses of paint model systems. In the end, the method was successful in detecting madder lake in archeological samples from Greek wall paintings and on an Italian funerary clay vessel, demonstrating its capabilities to identify dyes in small amount of highly degraded samples.

“…MAK III category 2 dyes, which belong to the carcinogenic dyes used in the textile industry [1]) may cause skin allergies and other harm to the human body, in addition to producing toxic waste. Natural dyes are obtained from renewable sources such as crops, insects and so forth, and they may decrease the dependence on petrochemical sources [2][3][4]. These considerations have led to the publication of several studies on natural dyes from a number of sources [5][6][7][8][9][10][11].…”

ABSTRACT:In this study, silk fabric is dyed with natural indigo. Dyed silk fabric with natural indigo was cut in the 20x20 cm 2 size. Excluding a fabric, all fabrics were mordanted in the same percentage with alum metal (KAl(SO 4 ) 2 .12H 2 O). Then, silk fabrics for green color dyeing are dyed separately with weld (Reseda luteola), gall oak (Quercus infectoria Olivier) and together weld (Reseda luteola) and gall oak (Quercus infectoria) in different percentage. Antimicrobial functionality of the twenty seven silk fabrics is established. Tests were conducted against the Staphylococcus aureus ATCC 6538. The results of the counting test showed more reduction of survival Staphylococcus aureus in dark-colored fabric. The number of survival microorganism was determined by counting the colonies as colony-forming unit (CFU/ml) and reduction rate of bacteria was calculated. Coloring compounds and their percentages in the natural dyed silk fabrics are detected by HPLC-PDA (high performance liquid chromatography with diode array detection). Colour measurement is done of the dyed silk fabrics by CIEL*a*b* spectrophotometer.Keywords: Antimicrobial testing, natural dyeing, Staphylococcus aureus, HPLC-PDA, colour measurement. BAZI DOĞAL BOYALAR KULLANILARAK BOYANMIŞ İPEK KUMAŞLARIN ANTİMİKROBİYAL AKTİVİTESİNİN BELİRLENMESİÖZET Bu çalışmada, ipek kumaş doğal indigo bitkisi ile boyanmıştır. Sonra 20x20 cm 2 boyutunda kesilmiştir. Bir kumaş hariç tüm kumaşlar aynı yüzdede şap (KAl(SO 4 ) 2 .12H 2 O) çözeltisi ile mordanlanmıştır. Yeşil renk boyama için kumaşlar önce ayrı ayrı muhabbet çiçeği (Reseda luteola) ve mazı gomalağı (Quercus infectoria Olivier) ile daha sonra iki bitki beraber farklı yüzdelerde kullanılarak boyama yapılmıştır. Antimikrobiyel test 27 adet ipek kumaş için uygulanmıştır. Testler Staphylococcus aureus ATCC 6538 e karşı yapılmıştır. Sayım sonuçları koyu renkli kumaşlarda S.aureus' un daha fazla azaldığını göstermiştir. Canlı mikroorganizma sayısı CFU/ml olarak koloni sayımı ile belirlenmiştir. Bakteri azalması tayin edilmiştir. Boyama yapılmış ipek kumaşlardaki renk bileşenleri ve onların yüzdeleri HPLC-PDA (yüksek performanslı sıvı kromatografisi) ile renk ölçümleri ise CIEL*a*b* spektorofotometresi yardımıyla belirlenmiştir.
