Abstract
Basing on the experiment of single factor, the optimum extraction conditions of flavonoids from the leaves of sweet potato using ultrasonic method was studied according to the orthogonal design. The optimum extracting conditions were as following: 80 % alcohol, treating with ultrasonic for 45 min, 40 times volumes.
