Efficient optimization approaches for microwave assisted extraction of high-quality antioxidant compounds from Salvia officinalis L.: UHPLC-HRMS differential analysis of phenolic profiles obtained by ultrasound and microwave extraction
SUSTAINABLE CHEMISTRY AND PHARMACY(2023)
摘要
The study aims to optimize MAE of total phenolic compounds (TPC) and antioxidant capacity from Salvia officinalis L. leaves using a definitive screening design (DSD) and I-optimal design. UHPLC-HRMS analysis was used to identify and compare the composition of MAE and UAE optimal extracts. The results showed that DSD and I-optimal design were successfully applied for the optimization of MAE targeting phenolics and other antioxidants from S. officinalis L. with the following optimum conditions: 60% ethanolic solvent, time of 4.75 min, power of 600 W, and L/S ratio of 50 mL g-1. The UHPLC-MS analysis results allowed the identification of more than 80 compounds, and the differential analysis indicated that the MAE yielded a higher level of 181 substance peaks, while the UAE yielded a higher level of 87 substance peaks. This study provides valuable information for selecting the appropriate extraction technique when targeting specific compounds.
