Abstract:
In the aerial parts of Eschscholtzia californica CHAM., E. douglasii (HOOK. etARN.) WALP. and E. glauca GREENE the main alkaloidal component is the quaternary base californidine. Eschscholtzine, allocryptopine, and protopine belong among the dominant tertiary alkaloids, which are accompanied by a small amount of N-methyllaurotetanine and the quaternary benzophenanthridines (sanguinarine, chelerythrine, chelirubine, chelilutine, and macarpine). The pavinane alkaloids isonorargemonine, caryachine, norargemonine, and bisnorargemonine and the aporphine alkaloids corydine and isocorydine were isolated from the aerial part of the E. douglasii species for the first time. These alkaloids were also detected in E. californica and E. glauca. Corytuberine was also isolated from all three species. From the fraction of Quaternary alkaloids after conversion to iodides, in addition to californidine, escholamidine iodide was isolated from E. californica and E. douglasii species. From E. douglasii N-methylcaryachinium iodide and from E. glauca magnoflorine iodide were also isolated. The presence of a small amount of the mentioned quaternary alkaloids, as well as traces of escholamine were also detectable in all three species.

Abstract:

Limited inductive photoperiod (LIP) significantly reduced stem length but had no effect on the peduncle length, leaf number, plant diameter, days from seed to first flower or days from start of long days (LD) to first flower in Eschscholtzia californica. However with fewer LD cycles, negative effects associated with LIP included an increasing number of bud abortions and plants remaining vegetative, while the number of axillary buds decreased. Ancymidol [alpha-cyclopropyl-alpha-(4-methoxyphenyl)-5- pyrimidinemethanol] at 35, 45 and 50 ppm reduced stem length, but had no effect on peduncle length. Although plant diameter was significantly reduced, ancymidol had no effect on number of leaves or days to flower. There were no bud abortions, all plants flowered successfully, and there was no negative effect on axillary bud number with the use of ancymidol. Cycocel [(2-chloroethyl) trimethylammonium chloride] had no effect on stem length or the overall plant height in the Eschscholtzia californica. In addition, cycocel proved to be ineffective on associated vegetative growth and reproductive development.

Abstract:
Au cours des 30 dernières années, l'implantation industrielle des technologies de culture végétale s'est avérée inefficace. Cela s'explique en partie par le fait que les conditions de croissance de ces cellules ne sont pas optimales. Afin de déterminer les conditions optimales de culture, il faut d'abord modéliser la cinétique de croissance. Mais les modèles déjà existants ne sont cependant pas au point pour expliquer adéquatement toute la complexité de la croissance cellulaire. De plus, l'analyse de plusieurs variables est nécessaire pour bien comprendre cette complexité. Le premier objectif de cette maîtrise consiste à développer une plateforme à haute capacité analytique permettant d'effectuer le suivi de plusieurs cultures cellulaires. Cette plateforme est composée de 9 minibioréacteurs incorporés dans un robot pipetteur fredom Evo [indice supérieur Copyright] (TECAN). En plus de prélever de façon aseptique et automatique les cultures cellulaires, ce robot permet l'analyse en duplicata de 7 variables de croissance : le sucre total, le glucose, le phosphate, le nitrate, l'ammonium, la biomasse et le compte cellulaire. Les méthodes d'analyse sélectionnées sont simples, rapides, peu dispendieuses et nécessitent un faible volume d'échantillonnage. Pour chaque échantillon, seulement 400 [mu minuscule]L sont nécessaires pour effectuer l'analyse des 7 variables en duplicata. Pour 9 cultures, cela donne un total de 126 analyses. De plus, la séquence d'analyse ne prend qu'une heure à effectuer. Cette plateforme permet de tester et suivre différentes conditions de cultures en peu de temps, avec peu de matériel et main d'oeuvre. Cela a permis d'obtenir rapidement plusieurs suivis de culture qui ont servi à élaborer un modèle cinétique de croissance cellulaire. L'élaboration d'un modèle de croissance correspond au second objectif de cette maîtrise. Le modèle développé est de type ségrégué et non structuré. Plutôt que d'être basés sur des rendements constants (nutriment/biomasse), ce modèle utilise les ratios stoechiométriques des bilans de masse pour estimer la consommation de nutriments et la biosynthèse de produits. Ceci permet d'estimer l’effet de la concentration intracellulaire des différents substrats sur la cinétique de croissance. Le modèle cellulaire sélectionné pour tester la plateforme est une lignée de cellules d'Eschscholtzia californica (Pavot de la Californie) qui a été dédifférenciée et mise en suspension. Cet organisme a la capacité de produire la sanguinarine, un alcaloïde prometteur pour le traitement de plusieurs cancers. Ce modèle a démontré que les concentrations optimales d'absorption des différents substrats sont supérieures à 19 mM pour le glucose et le nitrate, à 1,9 mM pour le phosphate et à 8 mM pour l'ammonium. Ces valeurs optimales représentent les concentrations pour lesquelles on obtient plus de 95 % de la vitesse maximale ([mu minuscule] max) des réactions d'entré des nutriments dans la cellule.

Charles University in Prague, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany and Ecology, Hradec Králové, 2011. Diploma thesis. 65 p. The aim of the diploma thesis was to process the pool of quaternary alkaloids from Eschscholtzia californica CHAM. (Papaveraceae). By means of column chromatography two alkaloids were isolated and subsequently subjected to structural analysis (MS and NMR studies). The first substance was identified as a tertiary alkaloid allocryptopine, the second one was a quaternary base californidine. Both alkaloids have previously been isolated from E. californica. Both substances were tested for their inhibitory activity against human erythrocyte acetylcholinesterase (HuAChE) and human plasma butyrylcholinesterase (HuBuChE). The measured values for allocryptopine were IC50 (HuAChE) = 250 ± 22,2 μM and IC50 (HuBuChE) = 530 ± 28,2 μM. Californidine's values were IC50 (HuAChE) = 36,7 ± 0,9 μM and IC50 (HuBuChE) >1000 μM. Galanthamine (IC50 (HuAChE) = 6,9 ± 0,3 μM, IC50 (HuBuChE) = 156 ± 6,9 μM) and huperzine A (IC50 (HuAChE) = 0,25 ± 0,01 μM, IC50 (HuBuChE) >1000 μM) were used as positive controls.

Within the screening of plants that contains alkaloids inhibiting the activity of the human erythtocytic acetylcholinesterase and human serum butyrylcholinesterase Eschscholzia californica Cham. (Papaveraceae) was studied. This work connect to the diploma thesis Jakub Doležal (2008). The task was to separate of alkaloids subfraction nonphenolic of chloride soluble in chloroform. The mother liquor was divided into various fractions by column chromatography on silica gel using a mixture of chloroform and ethanol increasing polarity. 45 fractions were obtained, which were joined by TLC monitoring. The united fractions 30-34 was obtained 4.57 g pěnovité white substance. The obtained substance was identified by MS and NMR studies as escholtzin. Escholtzin inhibitory activity against acetylcholinesterase was IC50 = 519 ± 5.8 µM and butyrylcholinesterase was worth more than 1000 µM. The measured values were significantly higher than the IC50 values of standards (galanthamine, eserine),...
