[Studies on chemical constituents from the root of Mirablis jalapa].
OBJECTIVE
To investigate the chemical constituents from the root of Mirabilis jalapa.


METHODS
Compounds were isolated from 75% ethanolic extract of the titled herb by silica gel column chromatography, and their structures were elucidated by physical and chemical evidences and spectroscopic analysis.


RESULTS
Four compounds were obtained and identified as (2, 5-dioxoimidazolidin-4-yl)-urea (1), glycerin monoeicosate (2), boeravinone (3) and beta-sitosterol (4).


CONCLUSIONS
Compound (2) is a new compound, and compound (1) was obtained from this plant for the first time.
