lasianthus acuminatissimus/glycoside

A series of iridoid glycosides were isolated from the leaves of Lasianthus verticillatus (Lour.) Merr., belonging to family Rubiaceae. A new iridoid glycoside, lasianoside F (1), and three new bis-iridoid glycosides, lasianosides G-I (2-4), together with four known

Three new anthraquinones, lasianthurin B (1), C (2), lasianthuoside D (3), a new benzochromene, lasianthurin D (4), and a new furfural glycoside, lasianthuoside E (5), together with one known compound 4- hydroxymethyl-2-furaldehyde (6) were isolated from an alcohol extract of the root of Lasianthus

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,

Six new anthraquinones named lasianthuoside F (1), G (2), H (3), I (4), J (5), K (6) were isolated from an acetone extract of the root of Lasianthus acuminatissimus. Their structures were elucidated by physical and chemical evidence and spectral analysis.
