中文摘要:为考察一级一项和一级两项动力学模型对黄芩黄酮浸提过程的模拟效果,通过不同浸提温度下的黄芩黄酮浸提过程试验,采用最小二乘法回归分别计算两动力学模型的参数。结果表明:两模型对黄芩黄酮浸提过程的拟合效果都较为理想(R2>0.9800,RSD小于1.00%);但一级两项模型的快速、慢速浸提速率常数等参数随温度变化的趋势未能反映相应的物理意义。因此,一级一项动力学模型更适用于黄芩黄酮浸提过程的模拟。

Abstract:The parameters of one-component kinetic model (OKM) and two-component kinetic model (TKM) for extracting flavonoids from scutellaria radix were calculated when the kinetic curves at 4 different temperatures were obtained under 50% ethanol as solvent, liquor-to-solid ratio of 20g/mL and scutellaria radix particles with the size of 20~40 mesh as the experimental material. It indicates that both of the regression results of the two models fit the experimental data well with the correlation coefficient of regression (R2) more than 0.9800 and the relative standard deviation of regression (RSD) less than 1.00%. And although the regression result of TKM was better than that of OKM, the changing of some TKM parameters with temperature were unreasonable.

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.
