“…Natural dyes are mostly eco-friendly, less toxic, and less allergenic as compared with synthetic dyes (Feng et al, 2007;Vankar et al, 2007;Bechtold et al, 2003;Komboonchoo and Bechtold, 2009;Samanta et al, 2009;Sarkar and Seal, 2003). Natural dyes exhibit better biodegradability and generally have a better compatibility with the environment (Deo and Paul, 2000;Parvinzadeh, 2007, 2004;.…”

“…This provides an opportunity for reintroduction of natural dyes that could be considered as a suitable alternative to synthetic dyes, which have been known to cause health hazards due to their carcinogenic effects (Sewekow, 1988). A wide spread interest has emerged (Bechtold et al, 2003;Kenneth, 1973;Gulrajani and Gupta, 1992;Komboonchoo and Bechtold, 2009;Feng et al, 2007) in the dyeing of textile fibers using natural colourants on account of their better biodegradability and higher compatibility with the environment. India has an abundance of dye yielding plant species in different parts of the country.…”

“…Dyed cotton and wool yarns showed blue shade with negative values of b* and all yarns showed green shade with negative values of a* coordinate. Komboonchoo and Bechtold (2009) reported that optimum dye quality would require optimized dyeing baths of indigo which depends on pH, temperature, ratio of dyestuff and reducing agent, etc.…”

The role of natural indigo dye in alleviation of genotoxicity of sodium dithionite as a reducing agent

Indigo blue is a natural dye used for thousands of years by civilizations to dye fabric blue and it is naturally obtained from Isatis tinctoria. I. tinctoria is not only used for extraction of indigo blue color but also used medicinally in Traditional Chinese Medicine because of its active compounds. Sodium dithionite (Na 2 S 2 O 4 ) is used in dye bath for indigo blue extraction, but this reducing agent and its derivatives are major pollutants of textile industry and subsequently have hazardous influences on public health. Herein, the present study was designed to obtain the high yield of natural indigo dye but with low possible toxic effect. In this context, genotoxic effects of particular combinations of natural dye solutions obtained from Isatis tinctoria subsp. tomentolla with Na 2 S 2 O 4 as reducing agent were investigated. Dye solutions were obtained using two different pH levels (pH 9 and 11) and three different concentrations of Na 2 S 2 O 4 (2.5, 5 and 10 mg/ml). In addition to the dye solutions and reducing agent, aqueous extracts of I. tinctoria were assessed for their genotoxicity on human lymphocytes. For in vitro testing of genotoxicity, chromosomal aberrations (CAs), sister chromatid exchanges (SCEs) and mitotic indexes (MI) assays were used. Accordingly, Na 2 S 2 O 4 caused significant increases in CA and SCE as well decrease in MI but the genotoxic effects of sodium dithionite were reduced with natural indigo dye. As a result, aqueous extracts of Isatis leaves removed the toxic effects of sodium dithionite and showed anti-genotoxic effect. For the optimal and desired quality but with less toxic effects of natural dye, 2.5 mg/ml (for wool yarn) and 5 mg/ml (for cotton yarn) of Na 2 S 2 O 4 doses were found to be the best doses for reduction in the dye bath at Ph 9.
