中文摘要:采用三频恒温数控超声辅助提取技术优化了诃子总多酚提取工艺;通过比较试验和扫描电镜分析了该技术高效提取的原因;从Fick第一定律出发建立了诃子总多酚扩散动力学方程,并进行了验证。结果表明,恒温超声提取诃子总多酚最佳工艺条件为:乙醇体积分数60%、超声频率80kHz、超声功率180W、提取温度70℃;该工艺提取效率显著高于水浴振荡提取工艺(P<0.001);扫描电镜观察发现,恒温超声提取技术对原料粉末微观结构破坏更严重。结合Fick第一定律及超声提取动力学推导了恒温超声辅助提取诃子总多酚动力学方程;验证试验表明,在相应的范围内,提取时间对数和提取功率对数均与诃子总多酚浓度对数呈正比关系。结果表明:恒温超声辅助技术可用于诃子总多酚高效提取。

Abstract:In order to optimize the extraction of total polyphenols from Terminalia chebula Retz. (TCR), the extraction technology of total polyphenols from TCR were optimized by using ultrasound assisted extraction with constant temperature and three-frequency (UAE—CT & TF). The reasons for high efficiency of this extraction technology were analyzed by comparative experiments and scanning electron microscope (SEM). The dynamic equation of diffusion for the total polyphenols was determined and verified based on the first Fick theory. Results showed that the optimal parameters of extracting technology were as follows, the concentration of ethanol was 60%, ultrasound frequency was 80kHz, ultrasound power was 180W and extracting temperature was 70℃. The extraction efficiency of UAE—CT & TF dramaticlly exceeded that of water bath oscillator extraction (WBE) (P<0.001). The microcosmic structures of powders of raw material after being extracted by UAE—CT & TF were seriously destroyed from the analysis of SEM. The dynamic equation of diffusion for the total polyphenols extraction of TCR was determined based on the first Fick theory and ultrasound extraction dynamics. The verification experiment showed the logarithms of extraction time and power were all positively proportional to the concentrations of TCR total polyphenols. The technology of UAE—CT & TF was proved as a technology with high efficiency for extracting TCR total polyphenols.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
