Objective Explore the optimal process for extracting anthocyanins from red raspberry using ultrasonic-assisted methods.Method fresh red raspberry fruit was used as the test material， and methanol was chosen as the extraction solvent. A four-factor， three-level orthogonal experiment was conducted to explore the optimal process for extraction of anthocyanins from red raspberry.Result Under the conditions of a liquid-to-solid ratio of 1∶10 （g/mL）， an 80% methanol （volume fraction） was used as the extraction solvent， and after the treatment was undergone with 400 W ultrasound for 25 minutes， the anthocyanin extraction rate reached a maximum of 35.25 mg/100g.Conclusion The ultrasonic-assisted methanol solution extraction method for red raspberry anthocyanins is efficient and fast， and the optimized process parameters can provide a reference for the industrial production of red raspberry anthocyanins.
