Özet

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-glucopyranosyl 4,4 " -binaphthalene-8,8 " -O,O-di-beta -D-glucopyranoside and 2-acetyl-3-methyl-1,8-dihydroxynaphthalene-8-O-beta -D- glucopyranosyl (1-->3) beta -D-glucopyranoside on the basis of spectral analysis. The other napthalene glycosides were determined as nepodin-8-O-beta -D-glucopyranoside and torachrysone-8-O-beta -D-glucopyranoside by comparison of their spectral data with those previously reported.
