【摘要】 目的:考察主要因素对提取液中白藜芦醇稳定性的影响,为白藜芦醇的研究和应用提供参考。方法:采用正交试验法,以HPLC法检测提取液中白藜芦醇含量的变化研究白藜芦醇溶液的质量浓度、pH值、温度和保存时间对白藜芦醇稳定性的影响。结果:pH为3、质量浓度:0.5mg/mL,维持在50℃以下少于2.5h的条件下能够保持白藜芦醇的稳定。结论:以正交试验法来研究提取液中白藜芦醇的稳定性,可以综合考察多种因素对提取液中稳定性的影响,具有一定的可行性。更多还原

【Abstract】 Objective: To study the effects of primary factors on the resveratrol stability in extracting solution and to provide the reference for research and application of resveratrol. Methods: effects of resveratrol concentration, pH value, temperature, and holding period on resveratrol stability in extracting solution were studied by the resveratrol changes determined by HPLC in orthogonal design test. Results: the most steady condition of resveratrol is that the concentration of resveratrol is 0.5 mg/mL, pH value keep 3, the temperature retain the below of 50 ℃ and holding period less than 2.5 h. Conclusion: It is feasibility to study the stability of resveratrol in extracting solution with orthogonal design which can integrated survey the influence of several factors to the stability of extracting solution.更多还原
