[Chemical constituents from fruit of Panax ginseng].
OBJECTIVE
To investigate chemical constituents from the ripe fruit of Panax ginseng.


METHODS
The compounds were isolated and purified by chromatographic methods such as macroporous resin, sephadex LH-20, Bio-gel P-2, ODS and silica gel. Their structures were identified by their physical and spectral data(ESI-MS, 1H-NMR and 13C-NMR).


RESULTS
Eleven compounds were isola- ted and identified as arginyl-fructose (1), arginyl-fructosyl-glucose (2), L-pyroglutamic acid (3), p-hydroxybenzoic acid (4), 5-hydroxy-methylfuraldehyde (5), ginsenosides Rb1 (6), Re (7), Rg1 (8), Rb2 (9), Rc (10) and daucosterol (11).


CONCLUSIONS
Compounds 1-5 were obtained from the fruit of Panax ginseng for the first time.
