Acid-base indicator properties of dyes from local plants I: Dyes from Basella alba (Indian spinach) and Hibiscus sabdariffa (Zobo)
The acid-base indicator properties of aqueous and ethanol extracts from calyces of H. sabdariffa (Zobo) and a dye obtained from the ripe fruits of Basella alba (Indian spinach), two local plants, were investigated. A purple coloured dye obtained from the ripe fruits of Basella alba showed a λmax at 580nm, absorptivity of 0.2269 and was found to be photochemically unstable. A deep red coloured d...
متن کاملExploring and exploiting plants extracts as the natural dyes/antimicrobials in textiles processing
The large number of publications in the field of extraction, purification, modification, and process optimization of natural dyes and their application on textiles demonstrates the revival of natural dyes on textile coloration. The use of natural dyes is growing in popularity because of the quality of the natural dyestuff obtained, the environmental compatibility of the dyes and the substantial...
متن کاملEndosomal accumulation of pH indicator dyes delivered as acetoxymethyl esters.
Intracellular distributions of the putative cytosolic pH indicator dyes BCECF [2',7'-bis-(2-carboxyethyl)-5(and 6)-carboxyfluorescein], C.SNARF [5(and 6)-carboxy-seminaphthorhodafluor-1], and C.SNARF-calcein have been examined in Neurospora crassa and in murine fibroblasts (NIH-3T3 cells) under conditions in which both kinds of cells produce visible microscopic vacuoles. All three dyes were adm...
متن کاملChemical Sensing Using Indicator Dyes
T h i s chapter describes the des ign, f a b r i c a t i o n , a n d propert ies of mater ia ls that respond to the presence of a chemical species by a change i n their opt ical properties. Ideally, such effects are reversible. They may be detected by conventional methods of absorpt ion, reflection, or luminescence spectrometry, a n d appl ied i n various formats such as test strips and disposa...
متن کاملAcid-base indicator properties of sulfonephthaleins and benzeins in acetonitrile.
Sulfonephthaleins and benzeins differ only in the presence of a sulfonic acid group in the former. In aqueous medium, both exhibit two color changes, one from yellow to the strongly colored acid form in strongly acid medium, and one from yellow to the strongly colored basic form. The indicator constants of the sulfonephthaleins are about the same as those of the corresponding benzeins. In the p...
