Studies on the Constituents of Osmanthus Species. X. Structures of Phenolic Glucosides from the Leaves of Osmanthus asiaticus NAKAI

Abstract

Three new phenolic glucosides were isolated from the leaves of Osmanthus asiaticus NAKAI (Oleaceae). The structures of 1, 2 and 3 were determined to be 2-hydroxy-5-(2-hydroxyethyl)phenyl β-D-glucopyranoside, 4-(2, 3-dihydroxypropyl)-2, 6-dimethoxyphenyl β-D-glucopyranoside and D-threo-guaiacylglycerol 7-O-β-D-glucopyranoside, respectively, on the basis of chemical and spectral data.
