Essential oil and the prime compounds (eugenol and eugenol acetate) present in clove have numerous biological potentials and usages leading to the commercial importance. A symbiotic effect between sonication and the hydrotropic solution was investigated for selective extraction of valuable compounds, namely eugenol and eugenol acetate from the clove buds. The combined approach was aimed to lessen extraction time while maintaining selectivity by improving the mass transfer characteristics. Solubility study has assisted in selecting a suitable hydrotrope i.e. sodium cumene sulfonate for extraction. Using parametric study and optimization by central composite design, optimum conditions have been achieved as 38 °C temperature, 1.04 M NaCuS concentration, 8.2 g solid loading, 158 W sonication power and 30 min of extraction time with the extraction yield of 20.04 %. The prediction of the yield using models developed by the central composite design and an artificial neural network was within 5 % of the actual value, thereby providing aid for estimating the yield without experimenting. It was possible to reuse the hydrotropic solution after extraction without affecting the yield. The impact of sonication on clove buds has been assessed using the scanning electron microscope. In comparison with extraction using an open reflux system, ultrasound assisted hydrotropic extraction has tendered an eco-friendly and sustainable solution for isolating target compounds from clove buds.

使用超声波辅助水溶提取法从丁香花蕾中强化提取有价值的化合物

丁香中存在的精油和主要化合物(丁香酚和丁香酚乙酸酯)具有许多生物学潜力和用途,从而具有商业重要性。研究了超声处理和水溶助长溶液之间的共生效应,以从丁香芽中选择性提取有价值的化合物,即丁香酚和醋酸丁香酚。组合方法旨在通过改善传质特性来减少提取时间,同时保持选择性。溶解度研究有助于选择合适的水溶助长剂,即用于萃取的异丙苯磺酸钠。使用参数研究和中心复合设计优化,已实现最佳条件为 38 °C 温度、1.04 M NaCuS 浓度、8.2 g 固体负载、158 W 超声处理功率和 30 分钟提取时间,提取率为 20.04 %。使用由中央复合设计和人工神经网络开发的模型对产量的预测与实际值的误差在 5% 以内,从而有助于无需实验即可估算产量。萃取后可重复使用助溶溶液而不影响产率。已经使用扫描电子显微镜评估了超声处理对丁香芽的影响。与使用开放回流系统的提取相比,超声辅助水溶提取为从丁香芽中分离目标化合物提供了一种环保且可持续的解决方案。使用由中央复合设计和人工神经网络开发的模型对产量的预测与实际值的误差在 5% 以内,从而有助于无需实验即可估算产量。萃取后可重复使用助溶溶液而不影响产率。已经使用扫描电子显微镜评估了超声处理对丁香芽的影响。与使用开放回流系统的提取相比,超声辅助水溶提取为从丁香芽中分离目标化合物提供了一种环保且可持续的解决方案。使用由中央复合设计和人工神经网络开发的模型对产量的预测与实际值的误差在 5% 以内,从而有助于无需实验即可估算产量。萃取后可重复使用助溶溶液而不影响产率。已经使用扫描电子显微镜评估了超声处理对丁香芽的影响。与使用开放回流系统的提取相比,超声辅助水溶提取为从丁香芽中分离目标化合物提供了一种环保且可持续的解决方案。已经使用扫描电子显微镜评估了超声处理对丁香芽的影响。与使用开放回流系统的提取相比,超声辅助水溶提取为从丁香芽中分离目标化合物提供了一种环保且可持续的解决方案。已经使用扫描电子显微镜评估了超声处理对丁香芽的影响。与使用开放回流系统的提取相比,超声辅助水溶提取为从丁香芽中分离目标化合物提供了一种环保且可持续的解决方案。
