Two new ceramides from the fruit pulp of <i>Acanthopanax senticosus</i> (Rupr. et Maxim) Harms

<div><p>Two new ceramides, (3<i>S</i>,4<i>S</i>,5<i>R</i>)-3-octadecanoylamino-4-hydroxy-5-dodecane-2,3,4,5-tetrahydrofuran (<b>1</b>) and (3<i>S</i>,4<i>S</i>,5<i>R</i>)-3-[(2<i>R</i>)-2-hydroxyhexacosanoylamino]-4-hydroxy-5-[(4<i>E</i>)-dodecane-4-ene]-2,3,4,5-tetrahydrofuran (<b>2</b>), together with eight known compounds, eleutheroside A (<b>3</b>), eleutheroside B (<b>4</b>), eleutheroside E (<b>5</b>), 7-hydroxy-6-methoxy-coumarin (<b>6</b>), 6,7-dimethoxycoumarin (<b>7</b>), 5α,8α-epidioxyergosta-6,22-dien-3-ol (<b>8</b>), stigmasterol (<b>9</b>) and rutin (<b>10</b>), were isolated from the fruit pulp of <i>Acanthopanax senticosus</i> (Rupr. et Maxim) Harms. Their structures were elucidated by means of physicochemical properties and spectroscopic methods (1D, 2D NMR and MS).</p>
