Objective:
To isolate and identify chemical constituents from Phellodendron chinense.
Methods:
Chemical constituents were isolated by silica gel and Sephadex LH-20 column chromatography. The structures of the isolated compounds were determined by spectral means.
Results:
Ten compounds were isolated and identified as berberine (1), caffeic acid ethyl ester (2), iso-vanillin (3), ferulic acid (4), (+/-)-5,5'-dimethoxylariciresinol (5), Methyl beta-orsellinate (6), gamma-fagirine (7), (+/-)-Lyoniresinol (8), beta-sitosterol (9), stigmasterine (10).
Conclusions:
Compounds 2-6 are isolated and identified from this genus for the first time.
