For the present study Quercetin has been extracted and applied onto the gamma irradiated cotton. Fabrics and powder have been exposed to different absorbed doses and dyeing has been performed at various parameters. It is observed that 20 kGy is the optimum absorbed dose for surface modification of cotton. It has been also found that good colour strength has been obtained at 60 • C by dyeing optimal fabric for 40 min using dye bath of pH6 keeping liquor concentration of 1:30 and electrolyte concentration of 1 g. 7% of tannic acid as pre-mordant and 5% of Copper sulphate as post mordant was optimum conditions to get good fastness properties according to ISO standard methods. Quercetin from acacia bark under ionizing radiation can safely be used as possible substitute to reddish-brown synthetic dyes.

“…Today the main aspects in the selection of textile products that they should be non-toxic, have safe starting materials and finished products. The synthetic dyes contain toxic and carcinogenic chemicals that may lead to health hazards and cause water pollution 1,2 . The eco-standards narrated by different environmental agencies such as Environmental Protection Agency (EPA) and Food and Agriculture Organization (FAO) etc., have compelled the textile customers to choose the ecolabel products 3 .…”

Increasing awareness about safe products in textiles has developed the worldwide choice in natural colour based textiles. For the present study, barks of Acacia nilotica (Kikar) has been selected as source of natural flavone dye (querecetin). Both cotton fabrics and dye powder were exposed to UV radiations for 30, 45, 60, 90 and 120 min. Later on the dye was extracted using irradiated (RP) and un-irradiated dye powder (NRP) followed by dyeing of irradiated (RC) and un-irradiated fabric (NRC). Different dyeing variables such as temperature, time, pH, liquor concentration (M:L) and electrolyte concentration were optimized and dyeing was performed at these optimum coniditions. To improve colour strength and colour fastness properties different concentrations of mordants such as Cu (copper sulphate), Al (aluminum sulphate), Fe (iron sulphate) and tannic acid were employed. ISO standard methods were employed to determine the colour fastness to light, washing and rubbing to observe the effect of UV radiation on these fastness properties. The fabrics investigated in CIE Lab system using spectraflash showed that exposure for 90 min modifies the surface of fabric and dyeing for 50 min at 55 ºC, using 8 g/100 mL of salt using dye bath of pH 6 provides the best colour strength. It is also found that iron is the best mordant among other used that improves the colour fastness properties from moderate to good.

“…From the aerial parts of S. mollis eight compounds were isolated and named as (E)-phytyl epoxide, 7,11,15-trimethyl-3-methylenehexadecane-1,2-diol, loliolide, scopoletin, hexacosanol, octacosanol, β-sitosterol and daucosterol 6 and six new prenylated isoflavanones; sophoronols A-F, together with eight phenolic constituents were isolated from the roots of S. mollis 6,7 where sophoronol C and sophoronol E showed moderate antiplasmodial activity. Some authors [8][9][10][11][12][13][14] have studied chemical analysis and biological properties of various plants, more work is needed to explore the un explored plants. Because of many traditional and medicinal uses of this plant, it was further studied to evaluate phytochemical screening and various biological activities of different extract/fractions of the plant S. mollis.…”

Sophora mollis (S. mollis) belongs to Papilionaceae family 1. Genus Sophora contains 45 species which consists of small trees and shrubs. Genus Sophora is rich in flavonoids and alkaloids which include sophocarpine, sophoramine, oxymatrine, sophoridine and matrine. These alkaloids have various pharmacological effects and mainly used to relief from many diseases and chief effects are sedative, antipyretic, antihepatitis B virus inotropic and anti tumor effects 2,3. Numerous species of genus Sophora are traditionally used to treat various diseases like sore throat, dermatitis, dysentery, fever, eczema, inflammation, asthma, gastrointestinal hemorrhage, allergy and diarrhea 4. The seeds of S. mollis are frequently used to heal skin diseases and also helpful to kill vermin like cockroach, flee, rats, lice, pests and parasites 5. Extract of freshly grinded leaves are used to treat sore eyes and also helpful in relieving severe headache. Leaves and branches of S. mollis are also utilized by livestock as food. S. mollis is best soil binder and increase fertility. Roots of S. mollis enhanced the growth of hair and also impart dark colour to hairs. This plant is used
