AI Article Synopsis
- * Optimal conditions found were 61.14% ethanol concentration, an ultrasonic extraction time of 59.73 minutes, and a solvent ratio of 27.72:1, resulting in a polyphenol yield of 1.352%.
- * The results suggest that ultrasonic extraction is efficient for extracting polyphenols and that using central composite design can enhance extraction outcomes effectively.
Article Abstract
Objective: To optimize ultrasonic extraction technology process conditions of polyphenol from Scindapsus officinalis by the response surface method.
Methods: Based on ethanol concentration, ultrasonic time, the liquid-solid ratio of single factor experiment, the principle of design for 3 star factor 3 level response surface methodology was applied. With FC extraction method for determination of polyphenols, the response surface optimization extraction conditions were studied.
Results: The ethanol concentration of 61.14%, ultrasonic wave extracting time of 59.73 min and the ratio of solvent volume of 27.72:1 (Extract 3 times) were selected as the optimum conditions,the extraction yield of polyphenols was 1.352%, with the theoretical 1.361% for the relative error of -0.66%.
Conclusion: Ultrasonic extraction is a good method for saving time, energy and material,and can be applied to the polyphenols extraction. Central composite design-response surface optimization can get better ecasting results.
