[Studies on the chemical constituents from Tribulus terrestris].
OBJECTIVE
To investigate the chemical constituents of the fruit of Tribulus terrestris J..


METHODS
Various chromatographic techniques were used to separate the chemical constituents. ESIMS, IR, 1HNMR, 13CNMR and HMBC were used to determine the structures of the isolated constituents.


RESULTS
Two new compounds were isolated from the fruits of Tribulus terrestris J. and were identified as neohecogenin-3-O-beta-D-glucopyranosyl (1-->2)-beta-D-glucopyranosyl (1-->4)-beta-D-galactopyranoside (I); neohecogenin-3-O-beta-D-glucopyranosyl (1-->4)-beta-D-galactopyranoside (II).


CONCLUSIONS
Compounds I and II are new steroidal saponins.
