Abstract：

A　biphasic　solvent　system　consisting　of　ionic　liquids　(IL)　and　petroleum　ethers　was　applied　in　the　extraction　of　Eucommia　ulmoides　gum　(EUG)　from　pericarp.　Effects　of　IL　and　extraction　parameters　on　the　yield　and　purity　of　EUG　were　investigated.　The　results　showed　that　the　addition　of　IL　could　enhance　the　yield　and　purity　of　EUG　extracted　from　pericarp　comparing　with　the　traditional　alike　pretreatment　method.　FTIR,　XRD　and　1H　NMR　characterization　conformed　the　chemical　structure　of　EUG.　DSC　analysis　reviewed　the　partial　destruction　of　crystal　structure　and　the　disappearance　of　β-crystal　phase　of　EUG　extracted　by　biphasic　solvent　system,　resulting　in　the　decrease　of　the　melting　point　and　increase　of　glass　transition　temperature.　Moreover,　the　extracted　EUG　exhibited　high　tensile　strength　of　27.68　MPa,　excellent　elongation　at　break　of　1069%,　and　thus　high　toughness　of　181.45　MJ∙m−3.　Additionally,　the　excellent　reusability　of　IL　and　petroleum　ethers　showed　the　extraction　method　of　the　biphasic　solvent　system　promise　as　a　feasible　method　to　replace　the　traditional　alkali　pretreatment.　©　2022　Elsevier　B.V.
