摘要
Phytochemical investigation of the 70% ethanolic extract of the roots of Rubia oncotricha Hand.-Mazz. led to the isolation of 2 new anthraquinone glucosides named 1-hydroxy-2-hydroxymethyl-9,10-anthraquinone-11- O- β-D-glucopyranoside (1) and 1,3,6–trihydroxy-2-hydroxymethyl-9,10-anthraquinone-3- O- β-D-glucopyranoside (2), together with 5 known compounds (3-7). Their structures were elucidated by extensive spectroscopic data analysis (1-dimensional, 2-dimensional-nuclear magnetic resonance, and high resolution-electrospray ionization-mass spectrometry).
