Objective: To optimize ultrasonic extraction technology of procyanidins from seed of Osmanthus fragrans. Method: With yield of procyanidins as index
extraction time
extraction temperature
solid-liquid ratio and the concentration of ethanol were chosen as factors
based on single factor test
ultrasonic extraction technology was optimized by orthogonal test. Result: Optimum extraction technology was:extracted 25 min with 8 times the amount of 50% ethanol at 50 ℃. Conclusion: This optimized extraction process was quick and simple
and it could provide experimental basis for development and utilization of seed of O. fragrans.
