OBJECTIVE
To study the chemical constituents from the seeds of Allium cepa L., the constituents of the seeds of Allium cepa L.
METHODS
To isolate and purify by silica gel, macroporous resin HP-20, Sephadex LH-20, RP-18 column.
RESULTS
Seven compounds were isolated from the EtOH extract of the seeds of Allium cepa., their structures were elucidated by physico-chemical properties and spectroscopic analysis as tianshic acid (I), N-trans-feruloyl tyramine (II), beta-sitosterol-3 beta-glucopyranoside-6'-palmitate (III), sitosterol (IV), daucosterol (V), tryptophane (VI), adenine riboside (VI).
CONCLUSIONS
Compounds V-VIII are obtained from this plant for the first time, compounds I-IV are isolated from the genus Allium for the first time.
