title: Three new and antitumor anthraquinone glycosides from Lasianthus acuminatissimus MERR.
abstract: Three new anthraquinone glycosides, lasianthuoside A (1), B (2), and C (3), were isolated from the root of Lasianthus acuminatissimus MERR., The structural elucidation of these anthraquinones was mainly established on the basis of 1D and 2D NMR and HR-MS spectroscopic analysis. Ten known compounds, damnacanthol (4), damnacanthol 11-methyl ether (5), damnacanthol-3-O-beta-D-primeveroside (6), asperuloside (7), asperulosidic acid (8), deacetyl asperulosidic acid (9), a nonglycosidic iridoid (10), 2,6-dimethoxy-4-hydroxyphenol-1-O-beta-D-glucopyranoside (11), tachioside (methoxyhydroquinone-4-O-beta-D-glucopyranoside) (12), and isotachioside (methoxyhydroquinone-1-O-beta-D-glucopyranoside) (13) were also identified for the first time from this plant in the course of the phytochemical and spectroscopic investigation. In addition to this report, a preliminary evaluation of 13 compounds in treating rheumatoid arthritis and antitumor effects of six anthraquinones are presented.
