torachrysone/スイバ属

Three novel and two known naphthalene glycosides were isolated from the roots of Rumex patientia L. (Polygonaceae). The structures of the new compounds were established, respectively as 2-acetyl-3-methyl-6-carboxy-1,8-dihydroxynaphthalene-8-O-beta-D-glucopyranoside,

OBJECTIVE To study the chemical constituents from aerial part of Rumex patientia. METHODS The compounds were isolated and purified by silica gels and polyamide column chromatography. Their structures were elucidated by physicochemical and spectroscopic evidences. RESULTS Twelve compounds were

OBJECTIVE Investigating the chemical constituents in the root of Rumex patientia. METHODS Compounds were separated by rechromatography on silica gel. Their structures were determined by spectral analysis and chemical evidence. RESULTS Eight compounds were isolated and identified as

Investigation of the N-BuOH extract of the roots of Rumex nepalensis afforded two new seco-anthraquinone glucosides, nepalensides A and B, along with nine known compounds, torachrysone ( 3), rumexoside, orientaloside, orcinol glucoside, aloesin, lyoniresinol 3 alpha- O- beta- D-glucopyranoside,

Plants belonging to the genus Rumex (family Polygonaceae) are used worldwide in traditional medicine for the treatment of various diseases caused by different microorganisms (e.g. bacteria-related dermatologic conditions, dysentery and enteritis). The present study focused on the antibacterial

BACKGROUND The approximately 200 species of the genus Rumex (sorrel, Polygonaceae) are distributed worldwide (European, Asian, African and American countries). Some species have been used traditionally as vegetables and for their medicinal properties. Based on the traditional knowledge, different
