[Isolation and identification of alkaloids from Armeniaca mume Sieb].
OBJECTIVE
To study the alkaloids from Armeniaca mume Sieb.


METHODS
The alkaloids were extracted with chloroform from 80% alcoholic extract and concentrated. Then they were transferred into aqueous solution and absorbed by macroporous cation exchange resin. The concentrated total eluent was extracted with chloroform. The alkaloids were purified by recrystallization with petroleum ether and sublimation. Then they were determined by Fourier Transform Infrared spectroscopy, Mass spectrometry and Nuclear magnetic resonance etc methods.


RESULTS
Two alkaloids were separated and their structures were elucidated as 2,2,6,6-tetramethyl-4-piperidone and tert-butylurea on the basis of spectral evidence.


CONCLUSIONS
They are new alkaloids from A. mume.
