Planting of elderberry in Czech Republic, unlike abroad, do not reflect its importance. It correspond with lack of literary resources. The thesis is focused on monitoring of pathogens of genus Sambucus. The list and description of diseases and pests originators is presented. In years 2012 and 2013 in locality Botanical gardens and arboretum Mendel University in Brno and in Veleboř was monitored elderberry diseases and pests occurrence. On both localities was registered only light occurence of fungus Cercospora depazeoides (Desm.) Sacc. (1878) and aphid Aphis (Aphis) sambuci and on locality Veleboř the thrips, probably Thrips sambuci. During monitoring period dry weather dominated and for these reason the infection was rather slight, protective measures was not done.

Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of Pharmacognosy Candidate: Lenka Applová Consultant: doc. Dr. Jiřina Spilková, CSc. Microscopy of Sambuci fructus from cultivars of Sambucus nigra Sambucus nigra L. is the important plant of the traditional folk medicine, its knowledge is accepted in the pharmaceutical and food industry. The elderberry fruits are used as diaphoretic, diuretic, during the migraine and neurological difficulties. On the grounds of the rising demand the collection of the wild-growing berries do not suffice and that is the reason for growing the elderberry and its cultivated varieties in plantations. The cultivated varieties of elderberry, which are grown for the use of the fruits in the food industry, could be exactly provided the quality drug for pharmaceutical use. The thesis is focused on the research of the microscopic characteristics of the elderberries fruits wild-growing elderberry and its cultivated varieties Allesö, Bohatka, Haschberg, Mamut, Sambo, Sambu, Samdal, Sampo, Samyl and Weihenstephan, which originated from the Research and Breeding Institute of Pomology Holovousy Ltd. The berries of the wild- growing elderberry were obtained in the Botanical Garden of Medicinal Herbs of Faculty of Pharmacy in Hradec Králové. The...

The fruits of elderberry - Sambuci fructus are used in the pharmaceutical and food industry. Fruits contain anthocyanins and flavonoids in addition to cyanogenic glycoside sambunigrin, organic acids, vitamins, sugars. Fruits from cultivated varieties are not used in pharmaceutically yet. The content of anthocyanins in the fruits of Sambucus nigra L. varieties Alessö, Bohatka, Haschberg, Mammut, Sambo, Sambo, Samdal, Sampo, Samyl, Weihenstephan and wild elderberry was determined by spectrophotometry. The amount of anthocyanins was recalculated for dried fruits and expressed by percentage of cyanidin chloride. Cultivated varieties shown lower values of anthocyanins than wild elderberry excerpt for Samyl variety. Statistically significant differences were found between contents of anthocyanins of varieties.

1. Abstract Purpose of this thesis was to prove and determine antioxidant activity of flower extracts from black elder (Sambucus nigra L.) and compile summary of their content substances and effects. Sambuci flos is often used in natural therapy and food industry. The main content substances are flavonoids, phenolic acids, triterpenoids, further are contained in flowers sterols, mucilage, essential oils, tannins. Flavonoids are the most significant, specifically rutin and kvercetin, because they can show antioxidant, antiviral, anti-inflammatory and anticancer properties. Flowers are used mainly for their diuretic, diaforetic, expectorant, analgetic effects. Method DPPH (2,2-difenyl-1- pikrylhydrazyl) was used for determination antioxidant activity of methanolic flower extracts. Results of antioxidant activity were expressed as IC50 values (concentration of extract which causes 50% reduction of radical). The average observed IC50values were 0,79 mg/ml and 0,83 mg/ml. The individual IC50values have changed fluently during development of flowers, they range from 1,086 mg/ml and 0,701 mg/ml in both collections. Deviations can be caused by ongoing synthesis of the secondary metabolites.

Elderberry is a traditional herb which has always been used in folk medicine. The berries contain many biologically active compounds, from which antocyanins are the most important. The fruits also contain flavonoids, organic acids, suggars, cyanogenic glycosides and another compounds such as vitamins, tannins, amino acids, potassium, calcium and phosphorus. The berries are used in food industry for production of marmelade, fruit syrups, wine and another delicacies. The drug Sambuci fructus is currently a subject of interest in pharmacy and medicine. The research examines the beneficial effects of antocyanins on human health and the possible use of antocyanins in medicine and pharmacy. Antocyanins exhibit a strong antioxidant activity, which can potentially be used for treating cardiovascular, tumor or metabolic disorders. The possibility of using the antioxidant effects in treatment for example hyperlipidemia, obesity and metabolic disorder is investigated. The listed effects can be also important as protection against oxidative damage of cells in diabetes mellitus. The antiinflammatory and antiinfective action is also important, it was investigated for both viral and antibacterial infections. At the same time it was shown, that elderberry could act as an effective immunostimulant. The ability of...

Elderberry is very popular plant, that is due to its beneficial effects to human organism very reputable. The main content substances are flavonoids and anthocyanins. Fruits of this flower are available only seasonally (which is usual for most of flowers), so we have to search for alternative solution of getting them. One of these solutions is conservation. Nowadays there are lots of types of postharvest adjustment, so we have more opportunities to find an optimal concept for every one specific plant. The diploma thesis is focused on assessment of content of phenolic substances harvested in different parts of Hradec Králové. They were conservated at laboratory temperature, elevated (40řC, 60řC) and reduced (-18řC) temperature. Next part of thesis is focused on assessing of the content of anthocyanins in fruits, that had been conservated for 3 years in refrigerator. The theme was finding the best concept of postharvestal adjustment. Despite to the individual places of harvest, there were not mentionable differences found out in content of phenolic substances in fruits. Main differences in content of substances were caused by different temperature of conservating area. With the upper temperature the content of phenolic substances was lower. Storage in the fridge for 3 years did not have any influence...

The aim of this work was to find out the content of flavonoids in the flowers of eleven cultivars of black elder (Sambucus nigra L.) and determine if their contents differ according to the statistical significance. Preparing the list of effects and substances that are contained in the flowers was the goal as well. The drug Sambuci nigrae flos is mostly used for its content of flavonoids and hydroxycinnamic acids in the therapy of colds and diseases of the urinary and respiratory tract. Its benefits were confirmed also by studies testing antibacterial and antiviral activity, diabetes and obesity, effects on the immune system and also protection against UV radiance. The content of flavonoids was established by the spectrophotometric method that is listed in the Czech Pharmacopoeia 2009 in the article Sambuci nigrae flos as the method for the determination of content. The statistic evaluation of the differences in the flavonoids content between the cultivars was made by ANOVA and the Bonferroni test. The demand of Czech Pharmacopoeia 2009 on the minimal content of flavonoids is 0,80%. This requirement was fulfilled in the flowers of these cultivars: Albida, Heidegg 13, Riese auß Voßloch, Sambu, Samdal, Sampo and Samyl. On the opposite side, flowers of the cultivars Allesö, Aurea, Dana and Juicy did...

Flores das espécies Sambucus nigra, de origem européia, e Sambucus australis, nativa da América do Sul (Caprifoliaceae), denominadas sabugueiro e sabugueirodo- brasil, respectivamente, são utilizadas popularmente sob forma de infusão, como antiinflamatórias, laxativas e para condições febris resultantes de afecções do trato respiratório. Estudos prévios para S. nigra indicam compostos fenólicos como principais constituintes químicos, sendo estes relacionados às principais atividades biológicas avaliadas. Objetivando comparar esta espécie com Sambucus australis, foram realizadas análises botânicas macro e microscópicas das flores, identificando as principais diferenças entre as espécies, tais como o número de lóculos no ovário e presença de idioblastos cristalíferos em algumas estruturas, e observando os possíveis contaminantes (pedicelos). Também foram determinados os parâmetros farmacopéicos: cinzas totais e perda por dessecação. Após a análise química, foi escolhido o flavonóide rutina como marcador das espécies, para realizar análises quantitativas nas 31 amostras adquiridas e / ou coletadas, utilizando método de CLAE previamente validado. Soluções hidroetanólicas apresentaram maior capacidade de extração do produto alvo. Os limites mínimos de rutina observados para ambas as espécies foram de aproximadamente 0,65%. Também foram quantificados, por método espectrofotométrico, os flavonóides totais expressos em quercetina, sendo 0,93% e 1,46% os teores mínimos determinados para S.nigra e S. australis, respectivamente. O estudo da estabilidade acelerada (50°C ± 90% U.R.), avaliando a degradação dos constituintes químicos presentes permitiu sugerir a cinética de degradação de segunda ordem para da rutina nas duas espécies. Comparações de atividades biológicas das espécies foram realizadas pelos ensaios das atividades antiinflamatória (inibição do edema em pata de rato induzido por carragenina) e antioxidante (DPPH). Os resultados para o primeiro ensaio demonstraram ação equivalente em ambas as espécies para extratos hidroetanólicos a 80% (86% de inibição) e aquosos (81%), com atividade semelhante ao padrão indometacina (~83%); para a atividade antioxidante os extratos hidroetanólicos a 80% foram mais ativos (CE50 = 16 μg/ml) que os aquosos (CE50 = 27 μg/ml) em S. australis, e ambos extratos, superiores ao 28 extrato padronizado Gingko biloba (CE50 = 40 μg/ml) e aos extratos de S. nigra (CE50= 50 μg/ml – hidroetanólico e CE50= 32 μg/ml – aquoso). / Sambucus nigra (from Europe) and Sambucus australis (from South America) flowers (Caprifoliaceae), called sabugueiro and sabugueiro-do-brazil, respectively, are used in the folk medicine as anti-inflammatory, laxative and for respiratory diseases. Previous studies for S. nigra indicate phenolic compounds as the main chemical constituents, being related for these ones the biological activities reported. In order to compare this species with S. australis macro and microscopical analysis of the flowers were carried out to identify the major differences between the species, such as the number of ovary locules and idioblasts in some structures, verifying the possible contaminants (pedicels). The following Pharmacopoeia parameters were also determined: total ash and loss on drying. After the chemical analysis, it was chosen the rutin flavonol as the mark constituent for both species, to carry through quantitative analysis of the 31 acquired and/or collected samples, by previously validated HPLC method. Hydroethanolic solutions had shown greater capacity of extraction of the target product. The minimum limits of rutin observed for both species had been of approximately 0.65%. The total flavonoid content was also quantified by spectrophotometer method, being expressed as quercetin, finding 0.93% and 1.46% the minimum values for S. nigra and S. australis, respectively. The accelerated stability test (50 ºC ± 90% UR) that evaluate the degradation of the constituents, allowed to verify a kinetic degradation of second order for rutin in both species. Comparison of biological activities of these species was carried out using the antiedematogenic (rat paw edema) and antioxidant (DPPH) activities. The results for the first test showed an equivalent action for the hydroethanolic (86% of edema inibition) and aqueous (81%) extracts, exhibiting a similar activity to indometacin (~83%). For the antioxidant activity, the ethanolic extracts (CE50 = 16 μg/ml) were more active than the aqueous (CE50 = 27 μg/ml ) for S. australis, and, both extracts were superiors to the Ginko biloba (CE50 = 40 μg/ml) and to the S. nigra extracts (CE50 = 50 μg/ml – hydroethanolic and CE50 = 32 μg/ml - aqueous).

This master´s thesis focuses at bioactive compounds in edible berries during its culinary processing. Elderberries (Sambucus nigra L.) were selected as a representative of edible berries variety. Elderberry is known for presence of significant bioactive compound content and usage in traditional medicine. Elderberries were processed acording to common culinary recipes. Amount od selected bioactive polyphenolic compounds (chlorogenic acid, quercetin, rutin, anthocyanes) was detected accordingly. Additionally content of ascorbic acid was determined. On the basis of the experimental determination, it was found that anthocyanes and rutin are the most common compounds found in elderberries. All analytes in juices and sirups gradually decreased during the treatments and long-term storage. On the contrary, the content of quercetin increased with gradual modifications and storage. The highest decrease was observed for vitamin C content. The lowest values in the products from elderberries were reached by quercetin and ascorbic acid.
