This study was conducted to study the influence of plant density and irrigation on the content of phenolic compounds, i.e., phenolic acids and flavonols in cv. ‘Sevilla’ cauliflower curds. Levels of phenolic acids and flavonols were in the range of 3.0–6.2 mg and 25.4–87.8 mg/100 g of dry weight, respectively, depending on plant density and irrigation. Of the phenolic acids, caffeic acid was detected in the highest amount, followed by p-coumaric acid, sinapic acid, gallic acid, and ferulic acid. Of the two flavonols detected, the levels of quercetin were higher than those of kaempferol. The content of the detected phenolic acids (with the exception of ferulic acid) and both flavonols increased with increasing plant density. Furthermore, the concentration of phenolic compounds (with the exception of ferulic acid) was significantly higher under irrigation.

Ferulic and coumaric acids were determined by high-performance liquid chromatography in 21 oat genotypes supplied from the gene bank of the Research Institute of Plant Production in Piešťany (Slovak Republic) with the aim of selecting some genotypes suitable for the preparation of functional foods. The content of coumaric acid was higher than that of ferulic acid in 61.9% of samples. The latter acid exceeded proportionally the former one in genotypes with a low content of phenolic acids, namely in the amount of up to 50 mg/100 g of grain, especially in chaffless oats. Ferulic acid content varied in the range from 16.50 mg/100 g (cultivar Jakub) to 149.36 mg/100 g of grain (cultivar Izak). The content of coumaric acid ranged between 8.05 mg/100 g (cultivar Detvan) and 210.27 mg/100 g of grain (cultivar Izak). The fact that the samples were grown in the same year (2003) in one locality (Vígľaš-Pstruša, Slovak Republic) minimises the influence of soil and climatic conditions and proves that remarkable differences between the content of ferulic and coumaric acids and the total content of phenolic compounds were caused by the genetic outfit of oats. A high correlation was found between the contents of the total phenolic compounds, ferulic acid, coumaric acid and their sum. The corresponding correlation coefficients R had the values of 0.9229, 0.9141, and 0.9211, respectively. This correlation enables one to employ a simple and inexpensive method for the determination of the total phenolic compounds using Folin-Ciocalteu reagent for a rapid assessment of differences detectable in the content of the sum of ferulic and coumaric acids in oat samples in view of the selection of genotypes suitable for the preparation of functional foods.

South African lovegrass (Eragrostis plana Nees) is an aggressive and difficult-to-control species in grazing areas of the south of South America, whose invasion capacity is increased by its phytotoxic capability. The objectives of this work were to identify and quantify chemicals produced by the plant shoots, to evaluate the inhibitory capability of plant extracts on development of lucerne (Medicago sativa L.) and wheat (Triticum aestivum L.), and to determine the spatial distribution of phenolics in rhizosphere soil in an infested field. Extracts were obtained by exhaustive extraction of dry shoot biomass, using solvents in increasing order of polarity. Soil samples contained in the rhizosphere were collected from an infested field. Bioassays for determination of phytotoxicity of extracts on lucerne and wheat seedlings were conducted in a completely randomised design with four replicates. The extracts showed suppressive, stimulating or neutral effects on the development of the radicle, shoots, and total lucerne and wheat seedlings, with greater phytotoxicity, generally, of ethyl acetate and methyl alcohol extracts. In the shoot extracts, nine phenolic compounds were identified and quantified: caffeic acid, coumaric acid, ferulic acid, gallic acid, vanillic acid, catechin, epicatechin, resveratrol, rutin. Of these, four were identified in the soil: catechin, epicatechin, coumaric acid, ferulic acid. Catechin, epicatechin and ferulic acid showed similar distribution patterns in the soil profile, with higher concentrations detected on the surface and on the side opposite the plant crown, which indicates release by the decomposition of tissues deposited on the soil surface. Coumaric acid showed higher concentrations on the surface and in the deeper layer of the soil next to the plant, indicating release both from decomposition of the shoots and from the root system. Future work may explore the phytotoxicity of the analytes identified, either isolated or in admixture, using dose curves and an inhibitory response to target plant species.

Fractions enriched in the cell walls of wheat and barley scutella were prepared from isolated, ungerminated scutella. The cell-wall fractions were subjected to hot, alkaline extraction under an inert atmosphere. An ether extract was investigated for phenolic compounds by thin-layer chromatography using three solvent systems and by ultraviolet spectroscopy. The major autofluorescent component of the scutella of both wheat and barley is ferulic acid. There is apparently no p-coumaric acid.

Environmental Relevance

Peat bogs are valuable archives of environmental change, including climate history, landscape evolution, and atmospheric deposition of trace elements, fallout radionuclides, and organic contaminants. Maintaining the fidelity of peat samples during collection and handling can be challenging, given that bogs consist mainly of fossil plant materials that typically have a very low density and are easily compressed. The surface layers of bogs, which are dominated by living plants and poorly decomposed fibrous peats, are especially problematic. To extract peat monoliths, we use a Belarus corer for deep layers and a Wardenaar device for surface layers. Both corers are constructed using titanium alloys to improve strength, reduce weight, and minimize the risk of contamination by the trace metals of environmental relevance. In this review, we include detailed drawings of the Belarus corer and photographs of the modifications to the Wardenaar corer. Modifications to the motorized Noernberg corer for frozen peat are described, and a complete set of drawings provided. A summary is given of simple procedures to minimize the risk of metal contamination in the laboratory from slicing and subsampling the peat cores and milling the dried samples.
