When plants are exposed to various stress situations, their alkaloid concentration frequently is enhanced. This well-known phenomenon is presumably due to a passively enhanced rate of biosynthesis, caused by greatly elevated concentrations of NADPH in stressed plants. Here, we used Chelidonium majus L. plants, which accumulate high concentrations of dihydrocoptisine in their leaves, to study the impact of drought and salt stress on the biosynthesis and accumulation of alkaloids. In comparison to well-watered controls, in the transcriptome of the gene encoding the key enzyme in alkaloid biosynthesis, stylopine synthase, is enhanced in stressed C...

As antique as Dioscorides era are the first records on using Chelidonium as a remedy to several sicknesses. Inspired by the " signatura rerum " principle and an apparent ancient folk tradition, various indications were given, such as anti-jaundice and cholagogue, pain-relieving, and quite often mentioned-ophthalmological problems. Central and Eastern European folk medicine has always been using this herb extensively. In this region, the plant is known under many unique vernacular names, especially in Slavonic languages, associated or not with old Greek relation to "chelidon"-the swallow...

Chelidonium majus L. is a rich source of isoquinoline alkaloids with confirmed anti-inflammatory, choleretic, spasmolytic, antitumor, and antimicrobial activities. However, their chromatographic analysis is difficult because they may exist both in charged and uncharged forms and may result in the irregular peak shape and the decrease in chromatographic system efficacy. In the present work, the separation of main C. majus alkaloids was optimized using a new-generation XB-C18 endcapped core-shell column dedicated for analysis of alkaline compounds...

Chelidonium majus L. (greater celandine) has been used as an herbal medicine for several centuries. This study investigated an efficient method to purify chelidonine from the extract of C. majus L. using macroporous adsorption resins and evaluated the antifungal activity of chelidonine against Botryosphaeria dothidea as a model strain. Static adsorption and desorption tests revealed that D101 was the optimal resin for chelidonine purification. Pseudo-second-order kinetics model and Freundlich equation model were the most suitable for evaluating the endothermic and spontaneous adsorption processes of chelidonine on D101...

Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) is a complex that regulates several hundreds of genes, including those involved in immunity and inflammation, survival, proliferation, and the negative feedback of NF-κB signaling. Chelidonine, a major bioactive, isoquinoline alkaloid ingredient in Chelidonium majus, exhibits antiinflammatory pharmacological properties. However, its antiinflammatory molecular mechanisms remain unclear. In this work, we explored the effect of chelidonine on TNF-induced NF-κB activation in HCT116 cells...

Six pairs of previously undescribed 6-monosubstituted dihydrobenzophenanthridine alkaloids were separated as corresponding six scalemic mixtures from the aerial part of Chelidonium majus. The elucidation for the 2D structures of these alkaloids was achieved using regular spectroscopic and chemical methods. The assignment of scalemic-mixture nature was achieved using combined examinations of their NMR data, CD spectra, calculation of specific rotations, and chiral HPLC profiles. The identification for the relative configurations of alkaloids possessing two asymmetric carbons directly connected up by a rotatable sp3 -sp3 carbon-carbon single bond was significantly facilitated by discussing the erythro and threo relative configurations defined by the mutuality of the orders of decreasing steric hindrances between the two sets of ligands linked to the two chiral centers...

Thin layer techniques proved their usefulness in the analysis of plant extract material. Thanks to their low operation costs, high sample throughput and possibility to gather chromatographic data for the whole sample in a single act, they allowed to find, and in some cases identify, active ingredients often hidden in sophisticated plant extract matrices. It was also proved that the presence of a magnetic field changes the retention of some substances, and moreover changes the separation efficiency of chromatographic systems...

The most prominent alkaloid of Chelidonium majus is dihydrocoptisine, revealing the characteristic benzophenanthridine skeleton. To date, any informationon on the enzymes responsible for its biosynthesis and the related genes in C. majus is lacking. Based on sequence similarities to the corresponding methylenedioxy bridge-forming Cyt P450 enzymes involved in isoquinoline alkaloid biosynthesis in Eschscholzia californica, genes for a cheilanthifoline synthase and a stylopine synthase from C. majus were isolated, sequenced and heterologously expressed in yeast...

Plant non-specific lipid transfer proteins (nsLTPs) are small basic proteins, which mostly play a role in intracellular lipid transport and antimicrobial defense. Recently it was shown using shotgun proteomic approach that the whole plant extract of Chelidonium majus L. (Papaveraceae) contains relatively abundant nsLTPs. Therefore the aim of the work was to isolate and characterize nsLTP from C. majus latex. Results obtained using PCR approach with degenerate primers showed the presence of nsLTP protein in C...

Phenology is a key aspect of plant success. Recent research has demonstrated that herbarium specimens can provide important information on plant phenology. Massive digitization efforts have the potential to greatly expand herbarium-based phenological research, but also pose a serious challenge regarding efficient data collection. Here, we introduce CrowdCurio, a crowdsourcing tool for the collection of phenological data from herbarium specimens. We test its utility by having workers collect phenological data (number of flower buds, open flowers and fruits) from specimens of two common New England (USA) species: Chelidonium majus and Vaccinium angustifolium...
