Lobelia inflata L. is a medicinally important species that contains numerous piperidine alkaloids. The main alkaloid lobeline is used as a respiratory stimulant. Recently, there have been studies that report on its effect on the central nervous system, drug abuse, and multidrug resistance. We have studied the piperidine alkaloid formation of in vitro cultivated L. inflata on solid Murashige and Skoog medium. With the aim of increasing the anti-addictive lobeline production, we have investigated the effect of changing MgSO 4 levels of the medium. The compounds (−)-lobeline, norlobelanine, lobelanidine-(−)-8-ethyl-10-phenyl-norlobelionol, (−)-8-ethyl-10-phenyl-lobelionol, norlobeline, lobelidine, and lobelanine were identified by HPLC-tandem mass spectrometry (MS/MS). We studied the effect of changing the MgSO 4 levels on the content of lobeline and its derivatives for in vitro cultivated L. inflata. The highest lobeline content was measured in roots cultured on 185 mg L −1 MgSO 4 -containing medium; this value was 2.5 times higher (232.4 μg g −1 ) than in the control cultures. The greatest (fourfold) increase was observed in lobelidine (71.61 μg g −1 ). Addition of MgSO 4 at 740 mg L −1 resulted in the highest lobeline contents in the herba (aerial tissues; 267.8 μg g −1 ), whereas maximum lobeline production was achieved by a further increase in the MgSO 4 level (1,480 mg L −1 ), due to an intensive increase in biomass production. A slight increase was observed in the amount of lobeline derivatives in the herba grown in 740 mg L −1 MgSO 4 -containing medium. The most significant increase (25%) was recorded in the level of norlobelanine.

“…Recent studies indicated the chemo-attractant character of Lobelia inflata extracts, while lobeline had chemo-repellent effects [22,23]. For economic production, it is important to increase the biomass and alkaloid content of the plant by nitrogen treatments in vitro [24] and in the open field [25][26][27][28]. There was a favorable effect of changing the NH 4 + and NO 3 -concentrations on the biomass formation of both in vitro cultures [29][30][31] and aquacultures [32,33].…”

There is a renewed interest in lobelia alkaloids because of their activity on the central nervous system. Lobeline, the most active of them, a nicotinic receptor ligand and neurotransmitter transporter inhibitor, is a candidate pharmacotherapy for metamphetamine abuse. In the present work, high-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry in positive ion mode was used for investigating the alkaloid profile in Lobelia inflata L. Chromatographic separations were achieved on a Gemini C6-phenyl reversed-phase column providing good peak shape and improved selectivity. Being mostly 2,6-disubstituted piperidines, lobelia alkaloids presented abundant [M + H](+) ions with typical fragmentation. Identification was possible from a few specific ions, especially those resulting from excision of one of the substituents. Based on fragmentation pattern of lobeline as reference compound, 52 alkaloids were identified in the aqueous methanolic extract of L. inflata in contrast to the previously known some 20. Structural variability of these alkaloids identified arises basically from their substituents which can be phenyl-2-ketoethyl- or phenyl-2-hydroxyethyl units as well as their methyl-, ethyl- or propyl- homologues attached in different combinations. Several propyl homologue lobelia alkaloids and five hydroxypiperidine derivatives were found in the plant at the first time. In addition to 8-O-esters of 2-monosubstituted piperidine alkaloids previously reported by us in L. inflata, a 3-hydroxy-3-phenylpropanoic acid ester of hydroxyallosedamine ring-substituted was also identified as a new natural product. High-performance liquid chromatography-electrospray ionization tandem mass spectrometry can be successfully applied to Lobeliacae plant samples in the routine screening for new and known bioactive constituents, quality control of the crude drug, lobelia herba, alkaloid production studies, breeding and chemotaxonomy.
