OBJECTIVE
To investigate the chemical constituents from the root of Lasianthus acuminatissimus of Rubiaceae.
METHODS
Normal, reverse phase silica gel, macroporous resin column and HPLC chromatography were used for isolation. Spectroscopic methods (13C-NMR, 1H-NMR, DEPT, EI-MS) were used for identification.
RESULTS
Six compounds were isolated and elucidated as isoscopletin(I), isoscopletin-6-O-beta-D-glucopyranoside (II), beta configuration of Mudanoside-A (Ill), asperuloside (IV), (-)-pinoresinol 4-O-beta-D-glucopyranoside (V), daucosterol (VI).
CONCLUSIONS
These compounds were obtained from this plant for the first time.
