Abstract:
Objective To study the chemical constituents from the root of Rumex gmelini.MethodsThe compounds were isolated and purified by chromatography,polyamide column chromatography,and preparation HPLC etc.Their structures were elucidated by physicochemical and spectroscopic evidences.Results Ten compounds were identified as:nepodin (Ⅰ),emodin (Ⅱ),citreorosein (Ⅲ),chrysophanol 8-O-?-(6'-acetyl) glucopyranoside (Ⅳ),chrysophanol 8-O-?-D-glucopyranoside (Ⅴ),resveratrol (Ⅵ),9,9'-dianthranone-2,2'-dimethyl-5,5'-bis (?-D-glucopyranose)-9,9',10,10'-tetrahydro-4,4'-dihydroxy-10,10'-dioxo (trivial name:rumoside A) (Ⅶ),emodin-8-O-?-D-glucopyranoside (Ⅷ),resveratrol-3-O-?-D-glucoside (Ⅸ),and rutin (Ⅹ).Conclusion Compound Ⅶ is a new compound,named rumoside A.Compounds Ⅴ,Ⅷ,and Ⅹ are separated from R.gmelini for the first time.Compounds Ⅲ and Ⅳ are the compounds which have been found in the plants of Rumex L.for the first time.
