<jats:title>Abstract</jats:title><jats:p>In addition to fourteen known glycosides from leaves of <jats:italic>Quercus laurifolia</jats:italic> Michx., a new acylated triterpene soponin has been isolated and identified as 3‐<jats:italic>O</jats:italic>‐galloyl‐28‐β‐<jats:sc>D</jats:sc>‐glucopyranosyl diester of the 2α,3β,19α,23‐tetrahydroxyurs‐12‐ene‐28‐oic acid (<jats:bold>1</jats:bold>). The structure of the previously described α‐<jats:sc>D</jats:sc>‐glucopyranosyl ester of the 2α,3β,19α,23‐tetrahydroxyurs‐12‐ene‐28‐oic acid was revised to β‐<jats:sc>D</jats:sc>‐glucopyranosyl ester of the 2α,3β,19α,23‐tetrahydroxyurs‐12‐ene‐28‐oic acid (<jats:bold>2</jats:bold>).</jats:p>
