OBJECTIVE
To study the alkaloids of Macleaya cordata.
METHODS
The alkaloids were isolated and purified by various column chromatography as well as recrystallization. Their structures were identified by physico-chemical properties and spectral analysis.
RESULTS
Thirteen alkaloids were isolated and
OBJECTIVE
To study the alkaloids of Macleaya cordata and their anti-tumor activities.
