[Studies on chemical constitutents in seeds of Allium tuberosum Rottl].
OBJECTIVE
To study the chemical constituents in the seed of Allium tuberosum.


METHODS
Chromatography and spectral analysis were used to isolate the constituents and elucidate their structures.


RESULTS
Five compounds were isolated from the alcohol extracts of the seeds and identified as nicotianoside C, (22S)-cholest-5-ene-1 beta, 3 beta, 16 beta, 22-tetrol-1-O-alpha-L-rhamnopyranosyl-16-O-beta-D-glucopyranoside, daucosterol, adenosine and thymidine.


CONCLUSIONS
All the compounds were isolated from the seed of this plant for the first time.
