A new anthraquinone glycoside was isolated from the hydrophilic fraction of the Chinese medicinal plant Rhynchotechum vestitum. Its structure was determined as damnacanthol-11-O-β-glucoside by spectroscopic evidence. The occurrence of rubiadin-l-methylether-3-O-β-primeveroside, lucidine-3-O-β-primeveroside and rubiadin-3-O-β-primeveroside in the pl...

From the hydrophilic fraction of the Chinese medicinal plant Rhynchotechum vestitum, three anthraquinones were isolated. Munjistin-1-O-methyl ether is a new compound, its structure was determined on the basis of spectral analysis. The occurrence of rubiadin-3-O-β-glucoside and lucidin-3-O-β-glucoside in the plant and some of their spectral data are...

... This procedure yielded sixteen pure compounds (1–16), which were full identified by 1D and 2D NMR and HR-MS. The following fifteen known compounds were obtained: the iridoid glycoside deacetylasperulosidic acid (1) (Kamiya et al., 2002; Tzakou et al., 2007) and the anthraquinone lucidin primveroside (2) (Itokawa et al., 1983), rubiadin-l-methyl ether-3-O-b-primeveroside (3)(Lu et al., 1998), damnacanthol (4) (Rath et al., 1995), 3-hydroxy-2-(hydroxymethyl)anthraquinone (5) (Wu et al., 2009), alizarin-1-methyl ether (6) (Rath et al., 1995), morindone 6-O-b-primveroside (7) (Kamiya et al., 2008), rubiadin-1-methyl ether (8) (Rath et al., 1995), anthraquinone-2- carboxylic acid (9) (Zhang et al., 2010), 2-hydroxy-3- methyl-anthraquinone (10) (Fan et al., 2008), lucidin x-methyl ether (11) (Endale et al., 2013), tectoquinone (12) (Rath et al., 1995), morindone (14) (Borroto et al., 2010; Rath et al., 1995), soranjidiol (15) (Boisvert and Brassard, 1988) and 1-hydroxy-2- methylanthraquinone (16) (Itokawa et al., 1989) (Fig. 2). ...
... Liu et al. (1990) discovered a new anthraquinone from Rhynchotechum vestitum which they called rhynchotechol. Investigations have since been conducted in a search for the active compound, revealing new chemicals (Lu et al., 1998a(Lu et al., , 1998b. ...
