Abstract
Studying the obstacles associated with continuous cropping is necessary for sustainable agricultural production. Phenolic acids play an important role in continuous cropping systems, although their mechanism of action in these systems remains unclear. Using High-performance Liquid Chromatography, we characterized the changes in phenolic acid contents in soils that had been continuously cropped with tobacco for different time periods and evaluated the interactions between soil physicochemical properties, bacterial community structure and diversity, and phenolic acids. Prolonged continuous cropping was associated with a significant increase in the content of phenolic acids and a significant decrease in soil pH and bacterial diversity. A significant negative correlation between pH and phenolic acids content was observed, suggesting that soil acidification potentially leads to the accumulation of phenolic acids. The Mantel test indicated that phenolic acids were positively associated with relative bacterial abundance (R = 0.480, P < 0.01), signifying that the accumulation of phenolic acids is a potential factor leading to changes in bacterial community structure. Continuous cropping lowered the soil pH, which stimulated phenolic acid accumulation and consequently altered the bacterial community structure and diversity, ultimately impacting tobacco plant growth.

Abstract
Hydroxamic acids are important defense compounds in cereals and have been subject to extensive research. Two important hydroxamic acids in maize are 2-β-D-glucopyranosyloxy-4-hydroxy-7-methoxy-2 H-1,4-benzoxazin-3(4 H)-one (DIMBOA-glc) and its 8-methoxylated derivative (DIM2BOA-glc). The compounds are typically reported as resolved by mass spectrometry rather than chromatography, with DIM2BOA-glc quantified relative to DIMBOA-glc. Biphenyl HPLC columns, however, allow good separation of the two compounds at both the analytical and semi-preparative scale, enabling both isolation and absolute quantitation of both compounds. In combination with established sample treatment and chromatographic methods, biphenyl chromatography thus promises new possibilities for resolving benzoxazinoid glucosides.

Abstract
Phenolic acids constitute a group of potentially immunostimulating compounds. They occur in all medicinal plants and are widely used in phytotherapy and foods of plant origin. In recent years, phenolic acids have attracted much interest owing to their biological functions. This paper reviews the extraction and determination methods of phenolic acids in medicinal plants over the last 10 years. Although Soxhlet extraction and ultrasonic assisted extraction (UAE) are commonly used for the extraction of phenolic acids from plant materials, alternative techniques such as supercritical fluid extraction (SFE), and accelerated solvent extraction (ASE) can also be used. After extraction, phenolic acids are determined usually by liquid chromatography (LC) owing to the recent developments in this technique, especially when it is coupled with mass spectrometry (MS). Also detection systems are discussed, including UV-Vis, diode array, electrochemical and fluorimetric. Other popular techniques for the analysis of this group of secondary metabolites are gas chromatography coupled with mass spectrometry (GC-MS) and capillary electrophoresis (CE).

Comparison of the levels of bioactive benzoxazinoids in different wheat and rye fractions and the transformation of these compounds in homemade foods. Food Chem 2013; 141:444-50. [PMID: 23768378 DOI: 10.1016/j.foodchem.2013.02.109] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2012] [Revised: 01/08/2013] [Accepted: 02/26/2013] [Indexed: 11/23/2022]
Abstract
Benzoxazinoids are important phytochemicals found in wheat and rye that are associated with plant resistance against pathogens, and recent studies have emphasized the potential health-promoting role of these compounds i.e. anti-cancer, anti-allergy and anti-inflammation. Accordingly, an understanding of their distribution in seeds and the effect of different processing techniques on their transformation will be helpful in identifying the mechanisms of their production and distribution and will support the on-going efforts to utilize these compounds in health-promoting food products. The analysis of seed fractions obtained from the milling of wheat and rye showed significantly higher concentrations of these bioactive compounds in the germ than in the other fractions, i.e. the bran and endosperm. Di-hexoses of 2,4-dihydroxy-1, 4-benzoxazin-3-one (DIBOA-glc-hexose) and 2-hydroxy-1, 4-benzoxazin-3-one (HBOA-glc-hexose) were the predominant compounds found in the different wheat and rye seed fractions followed by DIBOA-glc and DIBOA. The soaking and boiling of three rye-based breakfast cereals resulted in considerable changes in the benzoxazinoid contents. The soaking of pearled rye promoted the conversion of DIBOA-glc-hexose into DIBOA-glc. When these cereals were boiled, the increase in the DIBOA-glc content was much lower than that observed for soaking. For rye flakes, the pattern of these benzoxazinoids was different from that in pearled rye seeds. A considerable amount of the benzoxazinoids was also leached into the water during soaking or boiling. This study contributes to the understanding of the underlying processes involved in the biochemical changes of benzoxazinoids and will be the basis for future studies on other food-processing techniques.

Abstract
Barley (Hordeum vulgare) is an important cereal that has many applications; as a human food, in malt products and as livestock feed. The content of soluble health-promoting fibers, β-glucans, varies substantially among barley varieties. In the present study, the content of secondary metabolites with potential positive health effects in different high- and low-β-glucan barley varieties was studied. Five different flavanols were isolated and identified: (2 R,3 S)-catechin-7- O-β-D-glucopyranoside (1), prodelphinidin B3 (2), procyanidin B3 (3), (+)-catechin (4) and procyanidin B1 (5). Procyanidin B1 has never been reported in barley grains before. The compounds were identified using 1H NMR and quadrupolar time-of-flight mass spectrometry. A quantitative analytical method was developed for prodelphinidin B3, procyanidin B3 and (+)-catechin in liquid chromatography triple quadrupole-linear ion trap mass spectrometry and these compounds were quantified in all varieties, together with four phenolic acids: ferulic acid, vanillic acid, p-coumaric acid and p-hydroxybenzoic acid. Catechin was the compound that was present at the highest concentration in all varieties. The variation, between cultivars, in catechin concentration varied four fold. A Principal Component Analysis indicated no correlation between concentrations of β-glucan and secondary metabolites. Concentrations of catechin and prodelphinidin B3 were strongly correlated, whereas the concentration of procyanidin B3 was not correlated with that of catechin or prodelphinidin B3. Either two different enzymes could be responsible for the dimerization of prodelphinidin B3 and procyanidin B3, or the affinity of the enzyme could be different whether the dimerization is between two catechin units or between units of gallocatechin and catechin.
