[Chemical constituents from branch of Broussonetia papyrifera].
OBJECTIVE
To investigate the chemical constituents from the branch of Broussonetia papyrifera.


METHODS
Column chromatographic methods were used to isolate the chemical constituents. ESI-MS and NMR methods were employed for their structural elucidation.


RESULTS
Six compounds were isolated and identified as (2S)-7, 3'-dihydroxy-4'-methoxyflavan (1), ergosterol peroxide (2), D-galacitol (3), sulfuretin (4), liriodendrin (5), graveolone (6), respectively.


CONCLUSIONS
Compounds 1-6 were isolated from the plant for the first time.
