“…Each colour is characterised by brightness, hue, and saturation, which cannot be systematised on a plane, and therefore it is presented in a coordinate system (on the x and y axes). The host herb harvested from Sers (12) and Geghard (11) was much darker (52.4 and 57.8, respectively) compared to plants harvested from other sites. This was a significant difference compared to plants harvested from Garni and Goght sites 1 and 2, where the L* value was 66.9 and 64.9, respectively.…”

AbstractSome holoparasitic species can become cultivated plants due to their unique chemical composition. A lot of bioactive contents are characteristic for them. Holoparasites of the family Orobanchaceae are known to be an important and rich source of polyphenols, especially metabolites of the phenylethanoid glycosides (PhGs) group. However, only a minority of the species in this family have been phytochemically tested. They are reported to have multiple biological and therapeutic effects and have been used for centuries in traditional Chinese medicine. This is the first study to present phytochemical profiling for a representative of genus Phelypaea. The chemical composition and biological activity in particular organs of the parasite, P. tournefortii, were determined. The interaction with its host, Tanacetum polycephalum (Asteraceae), from different places and altitudes was also studied. We presented the determination of polyphenolic compounds with the UPLC-PDA-MS/MS method, antioxidative effects and inhibitory activities, polyphenols, and nitrates content, ABTS•+, DPPH, FRAP, as well as colour parameters. The polyphenols profile of the parasite and host were different in quality and quantity. Identification of polyphenolic compounds revealed 41 compounds, 15 in the parasite (12 phenylethanoids and 3 anthocyanins), and 26 in the host (mainly flavonoids and phenolic acids). The amount and biological activity of polyphenolic compounds present in Phelypaea was very diverse and depended on the host plant and the parasite’s organs, as well as on population altitude. The results show that P. tournefortii is a potential source of functional and pro-health components. They also direct researchers’ attention to the parasite’s organs, host, and environmental influence.

“…This herb has a high and comparable antioxidant potential. It is widely used in Chinese medicine as a part of nutraceutical and medicinal preparations (Jedrejek et al, 2020). Owing to their unique properties, certain holoparasitic species like Cistanche are being considered for cultivation in specific regions of China (Xu et al, 2009).…”

“…It is generally recommended in antioxidant research that several different tests involving different mechanisms of interaction of active substances with radicals (e.g., radical scavenging and chelation of Fe and Cu metal ions) be used. The ability of natural phenolics to inactivate ROS depends on their chemical structure, including the location and number of hydroxyl groups (the presence/modification of catechol moiety is particularly important) [ 49 ].…”

Demonstrated limitations in the mineral and nutritional composition of refined flours have led to calls for the possibility of enriching them with health-promoting supplements, such as high-value non-cereal seeds. Teff and watermelon seeds have been found suitable for the production of gluten-free flour, but so far, their potential to enrich conventional baking flours has not been comprehensively studied. Hence, the present study aimed at farinographic evaluation of dough based on refined wheat flour with additions of whole white teff (TF) and watermelon seed (WSF) and pomace (DWSF) flours (tested levels 10%, 20%, and 30%), as well as possibly extensive chemical characterization of the plant material tested, including LC-MS/MS, GC-MS, total phenolics, flavonoids, melatonin, and antioxidant potential. Most of the rheological traits were improved in the flour mixtures compared to the base white flour: development time and quality number (above 1.6-fold increase), softening and stability time (up to 1.3-fold change), and water absorption (up to 6%). Overall, the best results were achieved after the addition of watermelon seed pomace. The DWSF material was characterized by the highest levels of P, Mg, Na (7.5, 1.7, 0.4 g/kg, respectively), and Fe and Zn (124 and 27 mg/kg), while TF was the richest in Ca (0.9 g/kg) and Mn (43 mg/kg). Protein and fat levels were significantly higher in watermelon seeds compared to teff (about double and up to 10-fold, respectively). Phytochemical analyses highlighted the abundance of phenolics, especially flavones, in TF, WSF and DWSF flours (244, 93, and 721 mg/kg, respectively). However, the value of total polyphenols was low in all materials (<2 mg GAE/g), which also correlates with the low antioxidant potential of the samples. Watermelon seed pomace was characterized by significantly higher melatonin concentration (60 µg/kg) than teff (3.5 µg/kg). This study provides new information on the chemical composition and application opportunities of teff and watermelon seeds.

“…The 1D and 2D NMR spectra of isolated compounds, including 1 H-, 13 C-DEPTQ (distortionless enhancement by polarization transfer with retention of quaternaries), selective TOCSY (total correlation spectroscopy), selective ROESY (rotation frame nuclear overhauser effect spectroscopy), 1 H-1 H-DQF-COSY (double-quantum filtered correlation spectroscopy), 1 H-13 C-HSQC (heteronuclear single quantum coherence) and 1 H-13 C-HMBC (heteronuclear multiple bond coherence) were recorded using an Avance III HD Ascend 500 MHz spectrometer (Bruker BioSpin, Rheinstetten, Germany) in deuterated methanol (MeOH-d4) at 30 °C. NMR spectra were calibrated to the signal of residual solvent: δ 3.31 for 1 H and 49.0 for 13 C [48,49].…”

It is not easy to find data in the scientific literature on the quantitative content of individual phytochemicals. It is possible to find groups of compounds and even individual compounds rather easily, but it is not known what their concentration is in cultivated or wild plants. Therefore, the subject of this study was to determine the content of individual compounds in the new Paulownia species, Oxytree, developed in a biotechnology laboratory in 2008 at La Mancha University in Spain. Six secondary metabolites were isolated, and their chemical structure was confirmed by spectral methods. An analytical method was developed, which was then used to determine the content of individual compounds in leaves, twigs, flowers and fruits of Paulownia Clon in Vitro 112®. No flavonoids were found in twigs and fruits of Oxytree, while the highest phenylethanoid glycosides were found in twigs. In this study, we also focused on biological properties (anticoagulant or procoagulant) of extract and four fractions (A–D) of different chemical composition from Paulownia Clon in Vitro 112 leaves using whole human blood. These properties were determined based on the thrombus-formation analysis system (T-TAS), which imitates in vivo conditions to assess whole blood thrombogenecity. We observed that three fractions (A, C and D) from leaves decrease AUC10 measured by T-TAS. In addition, fraction D rich in triterpenoids showed the strongest anticoagulant activity. However, in order to clarify the exact mechanism of action of the active substances present in this plant, studies closer to physiological conditions, i.e., in vivo studies, should be performed, which will also allow to determine the effects of their long-term effects.
