II Techniques d’extraction L’extraction par solvant est une technique qui consiste à faire passer, par solubilisation , la substance à extraire dans un solvant Ces techniques concernent surtout l’extraction des colorants 1 Extraction liquide-liquide L’extraction liquide – liquide s’effectue avec une ampoule à décanter



Comparisons between Conventional and Microwave-Assisted

utilization of microwave-assisted extraction has significant improvement in the extraction of natural colorant compared to traditional boiling method In fact, application of microwave irradiation method proved to be a rapid and improved technique for natural colorant



Evaluation of different extraction methods for extraction of

ultrasonic assisted extraction methods and extensively study their effectiveness for the ir edge over conventional method The comparative investigation of different extraction technique for extraction of colorants from Pterocarpus marsupium saw dust has been reported The extracted colorant has been used for cotton fabric dyeing



Extraction of Natural Dye from Ixora coccinea (Linn) Flowers
