Opis:: Agnieszka Gryszczyńska
Coltsfoot leaves are a traditional raw material, rich in polysaccharides and phenolics. The variability of the contents of these main compounds was determined, using plant material originated from 22 natural populations of Tussilago farfara L. growing in various regions of Poland.In the years 2008–2009, plants from each investigated population were collected in the Garden of Medicinal Plants in Plewiska near Poznań (Poland). Coltsfoot leaves were harvested in the middle of June and July of 2010, and then dried at room temperature. In these raw material we quantified swelling index (describing mucilage content) and spectrophotometrically: the amounts of total polyphenols, polyphenols unadsorbed on hide powder (non-tannin phenolics) and tannins (expressed as pyrogallol equivalent) as well as the sum of hydroxycinnamic acid derivatives (expressed as rosmarinic acid) and flavonoids (expressed as quercetin).The demonstrated results show the relatively high and balanced contents of the basic active compounds, especially flavonoids (0.7–1.3%) and polysaccharides (swelling index: 8.0–14.5). In addition, it was found that flavonoids and mucilage in coltsfoot leaves fluctuate in only a small range (V=11–13%), regardless of overshadow and the harvest time of raw material.

Opis:: The present study aimed to analyze the linear correlation between the production variables of biofuel based on cocoa (Theobroma cacao L.) mucilage in the city of Calceta - Manabí. The issue addressed was the generation of waste from cocoa farming, leading to contamination of aquifers and the land surface. The CCN-51 cocoa variety was used for the research, following the guidelines of the Completely Randomized Design (CRD), with the proportion of yeast (Saccharomyces cerevisiae) as the studied factor, in three quantities: 0.5 kg, 0.1 kg, and 0.025 kg, and two methods of sample dehydration: saline distillation and molecular sieves the interaction between factors generated six treatments, each of which was repeated three times. The study found significant differences in the variables of alcohol content and yield, while there were no differences in pH and ratio/biomass. Treatment T6 was identified as the most feasible for biofuel production, with a pH of 5.86, 83% alcohol content, 76.67 mL ratio/biomass, and 58.10% yield. Regarding the relationship between the production variables, the analysis of linear correlation revealed a strong, directly proportional correlation for all variables, with values ranging from 0.94 to 0.98.

Opis:: Nowadays there is a search for new alternatives to replace harsh and expensive chemical methods to wastewater treatments. The common methods include the usage of chemicals that negatively affect the environment and the human health. The cladodes of Opuntia ficus-indica (L.) Mill have a great potential for use in innovative, cheap, renewable and eco-friendly water treatment due to their flocculant properties. In this work, different water treatments including fresh cladodes, lyophilized cladodes and the material obtained through mucilage extraction were tested. The turbidity of the water was measured, and it was concluded that the use of 60 g of small pieces of fresh cut cladodes was the method with the best results, reaching 4 NTU of turbidity. It confirmed the ability of O. ficus-indica (L.) Mill cladodes to promote the flocculation of clay in water, enabling to turn the unused material waste into a useful raw material.

Tytuł:: Integument cell differentiation in dandelions (Taraxacum, Asteraceae, Lactuceae) with special attention paid to plasmodesmata
Autorzy:: Świątek, Piotr
Płachno, Bartosz
Kurczyńska, Ewa
Opis:: The aim of the paper is to determine what happens with plasmodesmata when mucilage is secreted into the periplasmic space in plant cells. Ultrastructural analysis of the periendothelial zone mucilage cells was performed on examples of the ovule tissues of several sexual and apomictic Taraxacum species. The cytoplasm of the periendothelial zone cells was dense, filled by numerous organelles and profiles of rough endoplasmic reticulum and active Golgi dictyosomes with vesicles that contained fibrillar material. At the beginning of the differentiation process of the periendothelial zone, the cells were connected by primary plasmodesmata. However, during the differentiation and the thickening of the cell walls (mucilage deposition), the plasmodesmata become elongated and associated with cytoplasmic bridges. The cytoplasmic bridges may connect the protoplast to the plasmodesmata through the mucilage layers in order to maintain cell-to-cell communication during the differentiation of the periendothelial zone cells.

Tytuł:: Immunodetection of pectic epitopes, arabinogalactan proteins, and extensins in mucilage cells from the ovules of "Pilosella officinarum" Vaill. and "Taraxacum officinale" agg. (Asteraceae)

Opis:: The main aim of this study was to compare the cytological difference between ovular mucilage cells in two Asteraceae species - Pilosella officinarum and Taraxacum officinale - in order to determine whether pectic epitopes, arabinogalactan proteins, or extensins are present. The immunocytochemical technique was used. Both the Taracacum and Pilosella genera have been used recently as models for understanding the mechanisms of apomixis. Knowledge of the presence of signal molecules (pectic epitopes, arabinogalactan proteins, and extensins) can help better understand the developmental processes in these plants during seed growth. The results showed that in Pilosella officinarum, there was an accumulation of pectins in the mucilage, including both weakly and highly esterified pectins, which was in contrast to the mucilage of Taraxacum officinale, which had low amounts of these pectins. However, Taraxacum protoplasts of mucilage cells were rich in weakly methyl-esterified pectins. While the mucilage contained arabinogalactan proteins in both of the studied species, the types of arabinogalactan proteins were different. In both of the studied species, extensins were recorded in the transmitting tissues. Arabinogalactan proteins as well as weakly and highly esterified pectins and extensins occurred in close proximity to calcium oxalate crystals in both Taraxacum and Pilosella cells.

Tytuł:: Integument cell gelatinisation : the fate of the integumentary cells in Hieracium and Pilosella (Asteraceae)

Opis:: Members of the genera Hieracium and Pilosella are model plants that are used to study the mechanisms of apomixis. In order to have a proper understanding of apomixis, knowledge about the relationship between the maternal tissue and the gametophyte is needed. In the genus Pilosella, previous authors have described the specific process of the "liquefaction" of the integument cells that surround the embryo sac. However, these observations were based on data only at the light microscopy level. The main aim of our paper was to investigate the changes in the integument cells at the ultrastructural level in Pilosella officinarum and Hieracium alpinum. We found that the integument peri-endothelial zone in both species consisted of mucilage cells. The mucilage was deposited as a thick layer between the plasma membrane and the cell wall. The mucilage pushed the protoplast to the centre of the cell, and cytoplasmic bridges connected the protoplast to the plasmodesmata through the mucilage layers. Moreover, an elongation of the plasmodesmata was observed in the mucilage cells. The protoplasts had an irregular shape and were finally degenerated. After the cell wall breakdown of the mucilage cells, lysigenous cavities that were filled with mucilage were formed.

Liście podbiału stanowią tradycyjny surowiec zielarski, bogaty w polisacharydy i związki fenolowe. W niniejszych badaniach określono poziom zróżnicowania zawartości wspomnianych związków czynnych. Jako materiał roślinny wykorzystano 22 naturalne populacje Tussilago farfara L., pochodzące z różnych regionów Polski. W latach 2008–2009 pobrano rośliny z każdej badanej populacji i założono kolekcję pochodzeniową w Ogrodzie Roślin Leczniczych w Plewiskach koło Poznania. Liście podbiału do analiz fitochemicznych zbierano w połowie czerwca i lipca 2010 r., a następnie suszono w temperaturze pokojowej. W pozyskanym surowcu zielarskim oznaczono wskaźnik pęcznienia (określający zawartość śluzów) oraz spektrofotometrycznie: poziom polifenoli ogółem, polifenoli nie wiążących się z proszkiem skórzanym i garbników (w przeliczeniu na pirogalol), a także sumę pochodnych kwasu hydroksycynamonowego (w przeliczeniu na kwas rozmarynowy) i flawonoidów (w przeliczeniu na kwercetynę). Prezentowane wyniki badań wskazują na relatywnie wysoką i wyrównaną zawartość głównych związków czynnych, szczególnie flawonoidów (0,7–1,3%) i polisacharydów (wskaźnik pęcznienia: 8,0–14,5). Stwierdzono, iż poziom wspomnianych grup związków zmienia się w małym zakresie (V=11–13%) i nie zależy od ocienienia roślin i terminu zbioru surowca.
