“…Naringenin derivatives were determined in fabrics mordanted with only alum and tin salt and then dyed (Table ). According to the results of HPLC analysis, naringenin was found at a higher rate than apigenin in the dyed fabrics at 276 nm . The maximum amount of naringenin was obtained from the first mordanting process.…”

In this study, silk fabric samples were dyed by various procedures using Helichrysum arenarium extracts. Alum, ferrous sulfate, stanium chloride, calcium nitrate, and potassium bitartrate were used as mordants. Reversed-phase high-performance liquid chromatography with diode-array detection was utilised for identification of the dyes present in the dyed silk fabrics and the plant extracts. The extraction of dyes was carried out with a hydrochloric acid/methanol/water (2:1:1 v/v/v) mixture. The colour coordinates and K/S values, as well as wash, light, and rub fastness, were determined.

“…The formation constants of complexes can be calculated using several techniques such as UV-Vis spectrophotometric method, NMR, and electrochemical methods [7][8][9][10][11][12][13][14] .The advantages such as simplicity, low cost and ease to use are the main reasons of variety application of potentiometric and spectrophotometric methods. Spectrophotometric methods have been utilized as an alternative to determine stability constants of complexes with large molar absorptivities because of its high sensitivity at concentrations of substance as low as 10 -6 M. Nowadays, the spectrophotometric techniques remain largely used in this field because of the easy interpretation and handling of the spectral data.…”

In traditional spectrophotometric determination of stability constants of complexation, it is necessary to find a wavelength at which only one of the components has absorbance without any spectroscopic interference of the other reaction components. In the present work, a simple multi-wavelength model-based method has been developed to determine stability constants for complexation reaction regardless of the spectra overlapping of components. Also, pure spectra and concentration profiles of all components are extracted using multi-wavelength model based method. In the present work spectrophotometric titration of several cationic metal ions with new synthetic ligand were studied in order to calculate the formation constant(s). In order to estimate the formation constants a chemometrics method, model based analysis was applied.

In this study, the short information was given about flavonoids giving yellow colour to plants present in nature. In addition to these, flavones, flavonols, flavanones and isoflavonoids as subgroups were also reviewed. Among these subgroups, flavones and flavonols are one of the most important classes of phenolic compounds. The information about the most important dye plants including flavonoids was also given in this study. The investigated plants are weld (Reseda luteola L.), onion (Allium cepa L.), young fustic (Cotinus coggygria SCOP), Anatolian buckthorn (Rhamnus petiolaris Boiss), dyer's greenwood (Genista tinctoria L.) and Spanish broom (Spartium junceum L.). The most important yellow dyestuff and the oldest European dye among these dye sources is known as the luteolin dye. The dye plants were used for yellow color dyeing in ancient and historical textile. Nowadays, flavonoids are reused for sustainable, non-toxic, green textile and environment friendly textile dyeing. In the same time, flavonoids have been used for natural lake organic pigment, cosmetic, pharmaceuitical industries. In recent years, it has been suggested to use flavones in textile dyeing, cosmetic, pharmaceutical, etc. industries by the World Health Organization (WHO). Therefore, we have aimed to contribute to similar studies theoretical and experimental in natural dyeing studies.Keywords: Flavonoid, natural dye, dye plant. ÖzBu çalışmada, doğadaki mevcut bitkilere sarı renk veren flavonoidler hakkında kısa bilgi verilmiş olup, ek olarak da, bu bileşiklerin alt grupları olan flavonlar, flavonollar, flavanonlar ve isoflavonoidler hakkında genel bilgiler sunulmuştur. Bu alt gruplar arasında flavonlar ve flavonollar fenolik bileşiklerin en önemli sınıflarından birisidirler. Flavonoidleri içeren en önemli boya bitkileri hakkında bilgiler de bu çalışmada verilmiştir. İncelenmiş bitkiler muhabbet çiçeği (Reseda luteola L.), soğan (Allium cepa L.), boyacı sumağı (Cotinus coggygria SCOP), cehri (Rhamnus petiolaris Boiss), boyacı katırtırnağı (Genista tinctoria L.) ve katırtırnağı (Spartium junceum L.)'dır. Bu boya kaynakları arasında en önemli sarı boyarmaddesi luteolin'dir. Anadolu ve Avrupa'ya özgü boyarmaddenin en önemlilerinden birisi olarak bilinir. Bir çok boya bitkisi antik ve tarihi tekstillerde sarı renk boyamacılığı için kullanılmıştır. Günümüzde, flavonoidler sürdürülebilir, toksik olmayan, eko tekstil ve çevre dostu tekstil boyamacılığı için yeniden kullanılmaya başlanmıştır. Aynı zamanda, flavonoidlerin doğal lak organik pigment, kozmetik ve ilaç endüstrisi için kullanımı yeniden artmıştır. Son yıllarda, Dünya Sağlık Örgütü (WHO) tarafından tekstil boyamacılığında, kozmetik ve ilaç endüstrileri ve benzeri alanlarda flavonların kullanımı önerilmiştir. Bu nedenle, bu çalışmada doğal boyarmaddelerin teorik ve deneysel benzer çalışmalara katkı sağlaması amaçlanmıştır.Anahtar Kelimeler: Flavonoid, doğal boya, boya bitkisi.
