Eucommia　ulmoides　gum　(EUG)　with　high　purity　was　extracted　directly　from　the　Eucommia　ulmoides　pericarp　using　a　biphasic　solvent　system　consisting　of　deep　eutectic　solvent　(DES)　and　petroleum　ether.　The　addition　of　DES　enabled　the　deconstruction　of　lignocellulose　and　the　exposure　of　EUG,　leading　to　the　efficient　dissolution　of　EUG　in　petroleum　ether.　The　extraction　rate　of　EUG　was　22.986　%,　and　the　purity　of　EUG　was　98.01　%.　The　chemical　structure　of　EUG　was　confirmed　by　FTIR　and　NMR　characterization.　XRD　and　DSC　analysis　reviewed　the　partial　destruction　of　crystal　structure　and　the　decline　of　β-crystal　phase　of　EUG　during　the　extraction　process.　Moreover,　the　extracted　EUG　exhibited　high　tensile　strength　of　10.360　MPa,　excellent　elongation　at　break　of　78.663　%　ascribed　to　the　unique　crystallinity　that　enhanced　the　flexibility　of　molecular　chains.　In　addition,　the　recycling　performance　of　DES　and　petroleum　ether　was　verified,　and　the　recovery　rate　were　up　to　94.04　%　and　82.60　%,　respectively,　indicating　that　this　method　is　expected　to　replace　the　traditional　pretreatment　method　for　extracting　EUG.　©　2024　Elsevier　B.V.
