Objective To select the optimum ultrasonic extracting method of polysaccharides from Rosa Laevigatae Michx in Guizhou. Methods Independent variables were solid-liquid ratio, extraction time and extraction temperature, dependent variable was extraction rate ratio of polysaccharides from Rosa Laevigatae Michx.Linear or nonlinear mathematic models were used to estimate the relationship between independent and dependent variables. Response surface methodology was used to optimize the process of extraction.Prediction was carried out through comparing the observed and predicted value. Results The optimum extraction condition for the polysaccharides was as follows: extracting at 75 ℃ for 60 min and ratio of liquid to solid 30??1 ( mL??g ) . The average extraction yield of polysaccharides was 37. 54% under the optimum extraction condition. Conclusion This optimized extraction process is simple and reliable for the extraction of polysaccharides from Rosa Laevigatae Michx in Guizhou.
