Ultrasonic Extraction of Resins from an Historical Textile
Ultrasound assisted extraction was applied on the historical textile as the most appropriate sample preparation step for the identification of the resinous binder. Fragile silk banner from the 19th century was analyzed for the presence of different resins. After the ultrasonic extraction with ethyl acetate in the ultrasonic bath, resinous materials and unknown sample from the banner were separated by thin layer chromatography. The multiple developments in benzene- methanol (95:5) system as mobile phase and silica gel layer as stationary phase were applied, and afterwards the video densitometry determination of the components was performed by means of video camera HV-C20. The shellac resin was determined as an important part of the complex binder.
