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