Abstract: The ultrasonic extraction technique has been used to extract coloring matter from Sargentodoxa cuneata and the application of coloring matter on wool fabric studied. The effects of temperature, ultrasonic power, extracting time and bath ratio on the extraction of coloring matter from Sargentodoxa cuneata have been studied. From the orthogonal experiment, the optimum extraction conditions are found to be 50ºC temperature, 90 min extracting time, 200 W ultrasonic power, and 1:50 bath ratio. It is also observed that the efficiency of the ultrasonic extraction at 50ºC is higher than the normal extraction at 100ºC, and this optimum extraction condition is stable, feasible, and has good repeatability. It has bright prospective in industrialization. Color of the fabrics dyed by ultrasonic extracting solution is found to be deeper.
