Six new anthraquinone glycosides from Lasianthus acuminatissimus Merr.

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.

Three new Anthraquinones, one new Benzochromene and one new Furfural glycoside from Lasianthus acuminatissimus.

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 acuminatissimus. Their structures were elucidated on the basis of extensive spectroscopic data analysis (including 1D, 2D NMR, X-ray, and MS experiments) and comparsion to literature data.
