Title: Optimization of Water Extraction Technology for Chlorogenic Acid from Eucommia ulmoides Oliver. Leaves by Response Surface Methodology
Abstract: [Objective] To optimize the water extraction conditions for chlorogenic acid from Eucommia ulmoides Oliver.leaves,so as to provide theoretical evidence for the industrialized production of Eucommia ulmoides Oliver.leaves chlorogenic acid.[Method]Solid to liquid ratio,extraction temperature,extraction times and extraction duration were employed to design response surface analysis based on single factor test using yield of chlorogenic acid as response value,optimizing the extraction conditions of water extraction.[Result] The optimum extraction conditions for chlorogenic acid from Eucommia ulmoides Oliver.leaves were: solid to liquid ratio of 1∶ 16,extraction duration of 20 min,extraction times of two and extraction temperature of 65 ℃.Under the optimal process,the extraction rate of chlorogenic acid from Eucommia ulmoides Oliver.leaves reached as high as 92.55%.[Conclusion] In comparison with traditional extraction methods,water extraction technology was higher in extraction rate,less in energy consumption,shorter in extraction duration and lower in cost,and this case provided theoretical evidence for industrialized production of chlorogenic acid from Eucommia ulmoides Oliver.leaves.
