Sensitivity Analysis Of Vynyl Sulphone And BisMonochlorotriazine Reactive Groups Of Reactive Dyes

Reactive dyes contain different types of reactive groups which have different levels of sensitivity. Reactive dyeing is carried out by exhaust method on cotton knit fabric. A trichromatic combination is chosen containing vinylsulphone and bis-monochlorotriazine reactive groups. Dyeing of fabric is carried out with standard condition and variation of the conditions (electrolyte concentration, pH, exhaustion time, fixation time and M:L). Colorimetric data (DE*) is produced by comparing the difference between standard shade and the resulting shades by using spectrophotometer. Between the investigated reactive groups of reactive dye bismonochlorotriazine shows lower sensitivity in other terms higher robustness than vinyl sulphone

PHYTOCHEMICAL AND PHYSICOCHEMICAL ANALYSIS OF MICROWAVE-ASSISTED EXTRACTION CORIANDRUM SATIVUM L. LEAVES AND ITS BIOLOGICAL EVALUATION

Objective: The main objective of the present work is to carry out the phytochemical constituent present and physicochemical analysis of microwave-assisted extract (MAE) of Coriandrum sativum leaves and to investigate its antibacterial activity. Methods: The powdered samples of the leaves were extracted and analyzed for physicochemical properties. Extraction was carried out for C. sativum using different solvents and used for phytochemical investigation. Infrared (IR) spectrum and antibacterial activity of MAE were carried out. Results: The results show that the percentage extract is different in the different solvents and also differs in phytochemical constituents. Phytochemicals present in the MAE also confirmed by IR spectroscopy. MAE is active against bacteria. Conclusion: The phytochemicals present in C. sativum is confirmed by IR spectrum and these phytochemicals responsible for antibacterial activity
