[Isolation and structure elucidation of chemical constituents from Pinellia ternata].
OBJECTIVE
To isolate and identify the chemical constituents of ethanol extract of Pinellia ternata.


METHODS
The constituents were isolated by silica-gel, Sephadex LH-20 chromatography and HPLC techniques. The structures were identified by spectroscopic analysis including 2D NMR techniques and chemical properties.


RESULTS
Nine compounds were obtained and identified as uridine (1), 5'-S-methyl-5'-thioadenosine (2), adenine (3), chrysophanol (4), 5-hydroxymethylfurfural (5), nicotinamide (6), (2S)-1-O-(9Z, 12Z-octadecadienoyl)-3-O-beta-galactopyranosylglycerol (7), daucosterol (8), beta-sitosterol (9).


CONCLUSIONS
Compounds 2, 6, 7 are isolated from this plant for the first time.
