Steam Explosion as a Green Pretreatment Strategy to Enhance Total Phenolics Release and Biological Activities in <i>Potentilla discolor</i> Bunge Stems.

ABSTRACT: To efficiently, sustainably, and rapidly extract bioactive compounds, steam explosion (SE) technology was tried to use for the first time as a pretreatment of Potentilla discolor Bunge (PDB) stems. This study systematically investigated the effects of SE on stem structure, total phenolic content, composition and bioactivities. Macroscopic observation showed that SE-treated stems became darker and deeper in color. Microscopic analysis indicated a reduction in hemicellulose and lignin contents, while the basic skeletal structure remained intact, which facilitated the release of active compounds. This structural modification was directly linked to an enhancement in biological activity. Compared with the untreated group, total phenolic content in SE-treated stems increased 1.11-1.94 tim
