建立了一种从木豆叶提取物中分离球松酯的高效连续系统，该系统采用阳离子交换树脂柱（固定床柱反应器）连接聚酰胺树脂柱（固定床柱分离器）。以苯乙烯-二乙烯基苯为骨架、带有-SO 3-官能团的NKC-9阳离子交换树脂为催化剂，将球松酯查尔酮转化为吡醚菌酯，动态转化率为97.67 ± 1.82%。采用聚酰胺树脂柱对转化反应后的木豆叶提取液中的球松酯进行吸附，确定了最佳吸附条件。吸附平衡后，将30-70%的乙醇注入聚酰胺树脂柱作为解吸溶剂，从中收集50-70%的乙醇洗脱液作为最终产物，并用30-40%的乙醇洗脱杂质。该系统大大提高了产量，干品中球松酯含量从2.32 ± 0.16%增加到57.23 ± 1.18%，增加了24.67倍，球松酯的最终回收率为151.12 ± 1.53%。
An efficient continuous system for separation of pinostrobin from pigeon pea leaf extract using a cation exchange resin column (fixed-bed column reactor) connected to a polyamide resin column (fixed-bed column separator) was developed in this study. An NKC-9 cation exchange resin, with a styrene divinyl benzene matrix and –SO3– functional groups, was used as a catalyst to transform pinostrobin chalcone into piostrobin, with a dynamic transformation efficiency of 97.67 ± 1.82%. A polyamide resin column was used to adsorb pinostrobin from the pigeon pea leaf extract solution after the transformation reaction, and the most optimal condition was identified. After adsorption equilibrium, 30–70% ethanol was injected into the polyamide resin column as a desorption solvent, from which 50–70% ethanol eluates were collected as the final product and 30–40% ethanol was used to wash out impurities. This system greatly improved production, yielding a 24.67-fold increase in pinostrobin content in the dry product from 2.32 ± 0.16% to 57.23 ± 1.18%, and a final recovery of pinostrobin of 151.12 ± 1.53%.
