<div><p>From the <i>n</i>-BuOH-soluble fraction of a MeOH extract of the fruits of <i>Rosa soulieana</i>, one new phenolic glucoside (<b>1</b>) was isolated along with five known compounds, comprising two lignin glycosides, two flavonoid glycosides and a phenolic glycoside. The chemical structure of the new compound was elucidated by extensive spectroscopic analyses, including ESI-MS, UV, IR, <sup>1</sup>H and <sup>13</sup>C NMR, DEPT and 2D NMR (HSQC and HMBC). All the isolated compounds were evaluated for their antioxidant activity by using ABTS (2,2′-azino-bis(3-ethylbenzoline-6-sulfonic acid)) assay. Among these compounds, <b>1</b>, <b>3</b> and <b>6</b> exhibited strong scavenging activity in ABTS<sup>√+</sup>(SC<sub>50</sub> = 102.10, 193.85, 65.38 μmol/L, respectively) compared with the positive control l-ascorbic acid (<i>Vc</i>) (SC<sub>50</sub> = 117.16 μmol/L).</p></div
