“…Growth of carrot rosettes as shown in Table 1 was adversely affected by Cu treatment particularly at the 100 μM where after 24 weeks of cultivation significant decreases in the total number and weight of regenerated rosettes were observed in both cultures. Similarly as in our experiments a significant inhibition of biomass accumulation of chamomile cultures was observed in the presence of 120 μM Cu by Kováčik et al (2008). This is consistent with the reports of other authors about growth reduction in plants induced by Cu although its harmful concentrations vary considerably (Wiśniewski & Dickinson 2003, Alaoui-Sossé et al 2004.…”

“…The TBARS content of the Cu-treated Feria rosettes did not differ statistically from the controls after both 16 and 24 weeks of incubation. These results are similar to those reported by Kováčik et al (2008) in the leaf rosettes of Cu-treated Matricaria chamomilla but contradictory with those observed in Hydrilla verticillata (Srivastava et al 2006).…”

SummaryThe influence of copper ions on the regeneration of carrot (Daucus carota L.) androgenic embryos, accumulation of copper in rosettes, soluble esterbound phenolic acids and some parameters of oxidative stress were investigated. Two carrots: cv. Feria and 1014 breeding line were subjected to 1 μM, 10 μM and 100 μM Cu stress for 16 and 24 weeks. Under this stress, better growth, lower lipid peroxidation (TBARS level) and higher phenolic acid contents were observed in the cv. Feria. The rosettes of 1014 line accumulated less copper and produced smaller amount of TBARS after 24 weeks of incubation than after 16 weeks. Chlorogenic and caffeic acids were the main phenolic acids in both cultures. In the Feria rosettes the application of 10 μM Cu caused relatively high level of chlorogenic acid combined with low accumulation of copper in the tissues and unchanged levels of TBARS after both 16 and 24 weeks of incubation. On the other hand, despite the dose-dependent decline of chlorogenic acid in the rosettes of 1014 line, decrease in TBARS content was also observed after 24 weeks. The obtained results might suggest that the Feria carrot culture was able to develop more effective protection system/strategy against Cu excess in comparison to the 1014 line.

“…Secondary metabolites may contribute to antioxidant defense responses to copper stress in plants. Copper-induced accumulation of chlorogenic acid in M. chamomilla leaves could prevent lipid peroxidation [12]. Pre-treatment of leaf segments with the polyamine spermine prevented the loss of glutathione reductase enzyme activity and reduced increases in levels of lipid peroxidation and H 2 O 2 content induced by copper [13].…”

“…The quantification of lipid peroxidation has been used as an indicator of oxidative damage in leaves and roots of copper-exposed plants [7,[10][11][12][13][14]. Peroxidases such as guaiacol peroxidases (GPOD) are also considered to be reliable markers of metal stress.…”

“…Furthermore, incubation of wheat leaf segments in the presence of spermine prior to copper treatment prevented subsequent lipid peroxidation [13]. The copper accumulation in roots and leaves of Matricaria chamomilla increased the content of phenolic acids that may contribute to the avoidance of lipid peroxidation in leaves [12,23]. In Raphanus sativus shoots, the increases in cinnamic and benzoic acid derivatives and reduction in levels of ascorbate are dependent of the copper concentration.…”

Betacyanin accumulation and guaiacol peroxidase activity in Beta vulgaris L. leaves following copper stress

2012

The effect of copper stress on betacyanin accumulation and guaiacol peroxidase (GPOD) activity in leaves of different age was evaluated in red beet (Beta vulgaris L. var. Crosby Egyptian) plants. In hydroponic culture, plants were treated with 0.3 μM (control), 50 μM, 100 μM, and 250 μM of CuSO 4 for 6 days. Copper was taken up and accumulated in old roots but was not translocated to leaves. However in young leaves, the increase of lipid peroxidation and reduction of growth were evident from day 3 of copper exposure; whereas in old leaves, the lipid peroxidation and growth were the same from either copper-treated or control plants. In response to copper exposure, the betacyanin accumulation was evident in young leaves by day 3, and continued to increase until day 6. Betacyanin only were accumulated in old leaves until day 6, but the contents were from 4 to 5 times lower than those observed in young leaves at the same copper concentrations. GPOD activity increased 3.3-and 1.4-fold in young and old leaves from day 3 of copper treatment respectively, but only in the young leaves was sustained at the same level until day 6. Old roots shown betacyanin in the control plants, but the betacyanin level and growth were reduced with the copper exposure. In contrast, young roots emerged by copper effect also accumulated copper and showed the highest betacyanin content of all plant parts assayed. These results indicate that betacyanin accumulation and GPOD activity are defense responses to copper stress in actively growing organs.

Evaluation of the quality of herbal teas by DART/TOF‐MS

2017

The paper focuses on the optimization, settings and validation of direct analysis in real time coupled with time-of-flight detector when used for the evaluation of the quality of selected herbal teas (fennel, chamomile, nettle, linden, peppermint, thyme, lemon balm, marigold, sage, rose hip and St. John's wort). The ionization mode, the optimal ionization temperature and the type of solvent for sample extraction were optimized. The characteristic compounds of the analysed herbal teas (glycosides, flavonoids and phenolic and terpenic substances, such as chamazulene, anethole, menthol, thymol, salviol and hypericin) were detected. The obtained mass spectra were evaluated by multidimensional chemometric methods, such as cluster analysis, linear discriminate analysis and principal component analysis. The chemometric methods showed that the single variety herbal teas were grouped according to their taxonomic affiliation. The developed method is suitable for quick identification of herbs and can be potentially used for assessing the quality and authenticity of herbal teas. Direct analysis in real time/time-of-flight-MS is also suitable for the evaluation of selected substances contained in the mentioned herbs and herbal products.
