lasianthus stipularis/関節炎

OBJECTIVE To study the active constituents for the treatment of rheumatoid arthritis from the ethyl acetate extracts of the roots of Lasianthus acuminatissimus Merr. METHODS Various chromatographic techniques were used to separate and purify the constituents. Their structures were established on the

The genus Lasianthus (Rubiaceae) consists of approximately 180 species, of which the greatest species diversity is found in tropical Asia. Some of the Lasianthus species have been used in folk medicine to treat tinnitus, arthritis, fever, and bleeding. Lasianthus verticillatus

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,
