Abstract

ABSTRACT The ultrasound-assisted extraction of Total Phenolic Content from Sesbania grandiflora L. leaves and its optimization with kinetics is dealt with in this study. The effect of extraction of solvents (ethanol–water composition), solid to solvent ratio (1:10–1:70), particle size (0.1–0.5x 10−3m), power (50–120 W), and extraction temperature (30–50°C) on total phenolic content (TPC) from Sesbania grandiflora leaf powder has been investigated. The overall optimized parameters for the ultrasound-assisted extraction of Total Phenolic Content from Sesbania grandiflora L. leaves are solid to solvent ratio of 1:50, particle size of 0.4–0.5 × 10−3m, power 120 W, extraction temperature 45°C with the maximum phenolic content of 14.37 × 10−3g GA/g. Comparatively, equilibration time of UAE (240 s) is very low than the conventional batch operation (960 s). A semi-empirical two parameter, Peleg’s model, assists in capturing the reaction kinetics where it elucidates the experimental behavior in a precise way. GRAPHICAL ABSTRACT

超声波提取田菁叶中总酚含量的动力学研究

本文研究了超声波辅助提取大花田菁叶中总酚含量的方法及其动力学优化。溶剂萃取（乙醇-水组成）、固溶比（1:10–1:70）、粒度（0.1–0.5x 10−3m）、功率（50–120W）和提取温度（30–50°C）对田菁叶粉总酚含量（TPC）的影响。超声波辅助提取田菁叶中总酚含量的总体优化参数为固溶比为1:50，粒径为0.4–0.5 × 10−3m，功率120 W，萃取温度45°C，最大酚含量14.37 × 10−3g GA/g。相比之下，UAE的平衡时间（240秒）比传统的分批操作（960秒）非常低。Peleg的半经验双参数模型有助于捕捉反应动力学，以精确的方式阐明实验行为。图形摘要
