[Studies on non-anthraquinones in Rheum officinale Baill].Zhongguo Zhong Yao Za Zhi. 2000 Oct; 25(10):612-4.ZZ
To investigate the non-anthraquinones from the root and rootstock of Rheum officinale.
The chemical constituents were obtained from the 85% alcohol extract of the radix and rhizoma of R. officinale by column chromatography and identified by spectroscopic analysis.
Ten non-anthraquinones were obtained, of which eight were identified by spectroscopic analysis as rheosmine, daucosterol, d-catechin, 6-cinnamoylisolindleyin, (-)-epicatechin-3-O-gallate, resveratrol-4'-O-beta-D-(6"-O-galloyl)-glucopyranoside, gallic acid, D-sorbitol.
Compounds rheosmine and D-sorbitol were obtained from the genus Rheum for the first time.
