The effects of the mechanochemical assisted extraction parameters hydroxypropyl-β-cyclodextrin (HP-β-CD) content, particle size, and circulating water temperature on the extraction yield of eleutheroside B were investigated. The mechanochemical assisted extraction process was optimized based on an orthogonal experimental design. The optimum process conditions were a HP-β-CD content of 23% (w/w), a particle size of D95 ≤ 44 μm and circulating water temperature of 40 °C. The mechanochemical assisted extraction process produced a higher eleutheroside B extraction yield, using a shorter extraction time and a greatly simplified process compared with traditional heat-reflux extraction, which makes mechanochemical assisted extraction a potential tool for eleutheroside B extraction from Eleutherococcus senticosus. Moreover, this technique used water as the solvent, making mechanochemical assisted extraction a less expensive and eco-friendly technique compared with traditional heat-reflux extraction.
