| Abstract:
Lobelia inflata L. contains piperidine alkaloids. The main alkaloid is the pharmacologically active lobeline. We have studied the effect of macroelements (Mg2+, Na+ and Ca2+) on the growth and alkaloid production of hairy root cultures of L. inflata (clone 8009/f4). Macroelements influenced characteristically the linear growth and biomass formation of hairy roots. The greatest biomass formed in B5 media containing 1000 mg/l MgSO4. It was found that the highest amount of lobeline (39 µg/g, dry weight) was reached at 75 mg/l CaCl2. The results suggest that the optimal nutrient mixture for the best lobeline production was the basal B5 medium (containing 150 mg/l CaCl2, 150 mg/l NaH2PO4) supplemented with 1000 mg/l MgSO4. | |
