学术论文｜Systematic Chemical Profiling and Quality Evaluation Framework for Essential Oil Derived from Epimedium brevicornu Maxim.

In this study, we systematically evaluated how extraction protocol, processing variables, and storage conditions influence the quality of essential oil (EO) isolated from Epimedium brevicornu Maxim. Supercritical fluid extraction (SFE) proved superior to all other methods tested, affording the highest yield and most consistent composition.. Furthermore, this study proposes a comprehensive quality standard for qualified Epimedium EO, covering key parameters such as sensory attributes (appearance, odor), physicochemi…
