Separation Methods and Seasonal Changes in Quinolizidine Alkaloid Composition of Maackia amurensis Rupr. et maxim. Shoots

The work studies seasonal changes in quinolizidine alkaloid composition in M. amurensis 1-4-year shoots. The influence of ionic force of solvent on extracting efficiency of quinolizidine alkaloids from vegetable materials was investigated.
The maximum efficiency was reached when ionic force of solvent extracting efficiency is equal to 3,5 mole/l. Using gas chromatographic - mass-spectrographic analysis 14 alkaloids were separated and identified.
Key words: maackia amurensis, shoots, quinolizidine alkaloids, ionic force, gas chromatography - mass-spectrometry, seasonal changes in alkaloid composition.
