[A new chromone glycoside from Cassia siamea lam].
OBJECTIVE
To study the chemical constituents of the stem of Cassia siamea.


METHODS
The compounds were isolated by chromatography on silica gel, and identified on the basis of spectral analysis.


RESULTS
Five compounds were isolated and identified as: beta-sitosterol (I), sucrose (II), n-octacosanol (III), 2-methyl-5-(2'-hydroxypropyl)-7-hydroxy-chromone-2'-O-beta-D-glucopyranoside (IV) and piceatannol (V).


CONCLUSIONS
Compound IV is a new compound. Compounds II, III and V were obtained from this plant for the first time.
