OBJECTIVE
To study the chemical constituents of Cremastra appendiculata.
METHODS
The compounds were isolated by repeated column chromatography with silica gel, Sephadex LH-20 and ODS-HPLC. The structures were elucidated by analysis of spectroscopic data(1H-NMR and 13C-NMR).
RESULTS
Ten compounds were isolated from the EtOAc extract in the tuber of Cremastra appendiculata. Their structures were identified as shancigusin I (I), 4-O-β-D-glucopyranosyl cinnamate (II), bulbocodin D (III), blestriarene A (IV), 7-hydroxy-2,4-dimethoxy phenanthrene (V), coelonin (VI), militarine (VII), gastrodine (VIII), 3-hydroxyphenylpropionic acid (IX) and cinnamic acid (X).
CONCLUSIONS
Compounds I-III, IX and X are isolated from Cremastra appendiculata for the first time.
