The chemical investigation of Rheum sublanceolatum has led to the isolation of two new constituents, the structures of which were identified on the basis of physical and spectroscopic analysis as 2-acetyl-3-methyl-6,8-dihydroxy-2,3,4,4-tetrahydronaphthalene-1-one-6-O-beta-D-glucopyranoside (1) and 2,5-dimethyl-7-hydroxychromone-7-O-beta-D-(6'-O-galloyl)-glucopyranoside (2).
