In this paper, we intend to present a classical method of extraction and analysis betanin from Algerian red beetroot, know the efficiency binary mixture (Ethanol-Water) on extraction. Also, content extract obtained using optical spectroscopic methods. This dye is natural pigment with high antioxidant power widely used as dye. addition, bioavailability reinforces its potential for future therape...

Report of a complication related to the use of 0.1% trypan blue during capsular staining of the anterior crystalline lens capsule in an extracapsular cataract extraction with intraocular lens implantation. The capsular dye was injected using an air-bubble technique, inadvertently, it was done using high pressure dispersing the dye through the zonules leading to a complete lost of red reflex, th...

Moringa oleifera seeds contain about 40% of highly valued oil due to its wide range of applications, from nutritional issues to cosmetics or biodiesel production. The extraction of Moringa oil generates a waste (65%-75% of seeds weight) which contains a water soluble protein able to be used either in drinking water clarification or wastewater treatment. In this paper, the waste of Moringa oleif...

We present mechanistic characterization of alternating current cloud point extraction (ACPE) in a microchannel. ACPE is our original technique for on-chip extraction and preconcentration of membrane-associated biomolecules [1]. Joule heating of nonionic surfactant micellar solutions plays an important role in ACPE, but temperature of solutions during the extraction has not been investigated. In...

Several methods (e.g., UV/H2O2 oxidation, adsorption, flocculation-precipitation) are normally employed to remove dye from water. A new technique based on liquid/liquid extraction using reverse micelles is proposed whereby recovery of solvent and reuse of dye is possible. Experiments were conducted by mixing a known quantity of dye in aqueous phase and solvent-containing surfactants in a simple...

A natural dye lawsone (2-hydroxy-1, 4-naphthoquinone) was isolated from dry leaves of Lawsonia inermis L., by extraction with clove oil, ethyl alcohol, water and its effectiveness as staining agent for angiospermic stem tissue was studied. Lawsonia revealed meta-chromatic property of staining. A 10%w/v crude extract of Lawsonia inermis L., leaves in ethyl alcohol and water were used for stainin...
