OBJECTIVE
To isolate and identify pronuciferine monomer.
METHODS
The primary compositions in the seed of Nelumbo nucifera were extracted by supercritical CO2 way, then isolated and purified by column chroatography fractionation and identified by HPLC, TLC, GC-MS.
RESULTS
A monomer was further

OBJECTIVE
To establish an HPLC method for the determination of four alkaloids, i.e., 2-hydroxy-1-methoxyaporphine, pronuciferine, nuciferine and roemerine, in Nelumbo nucifera and its alkaloid fraction.
METHODS
The determination was carried out at 35 degrees C on a Hypersil C18 column (4.6 mm x 250

OBJECTIVE
Nelumbo nucifera (Gaertn.) leaves are used widely in modulating obesity in traditional Chinese medicine. Our previous work demonstrated that aporphine alkaloids from it increased the glucose consumption in mature 3T3-L1 adipocytes. However, the underlying mechanisms of this increase remain
