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).
