Plant extract is a complex concoction of several phytochemicals, for instance, phenolics, sugars, flavonoids, xanthones, and others. In general, it said that hydroxyl-rich phenolics act as reducing agents metal ions, but little discussed about the stabilizing ligands nanoparticles (NPs). Thus, despite popularity plant extract-mediated synthesis NPs, phytochemical basis process exact mechanism are still unclear. Herein, systematic study was carried out to unveil St. John's wort (Hypericum...
Determining the role of plant secondary metabolites in stress conditions is problematic due to diversity their structures and complexity interdependence with different biological pathways. Correlation metabolomic data genetic background provides essential information about features metabolites. LC-MS analysis leaf from 100 barley recombinant inbred lines (RILs) revealed that 98 traits among 135 detected phenolic terpenoid compounds significantly changed level as a result drought stress....
In this study, the effects of treatment with Ag, Au, Cu, Pd, CeO2, CuO, TiO2 and ZnO nanoparticles (NPs) on plant secondary metabolism were tested using an untargeted metabolomic approach in cell suspension cultures Hypericum perforatum L. Variations accumulation metabolites observed after exposure to NPs. Overall, number compounds increased by metal NPs was higher than that oxides. Among oxide tested, Ag CuO respectively induced greatest changes metabolism. cellular bisxanthone (540.3 fold)...
Abstract Flavonoid conjugates constitute several classes of plant phenolic secondary metabolites including many isomeric compounds differing in the hydroxylation pattern and substitution their rings with different groups such as alkyls, acyls or sugars. These occur tissues mainly glycosides cases it is necessary to have reliable detailed information concerning structure these natural products. Our results were obtained using leaf extracts Arabidopsis thaliana Lupinus angustifolius which...
Passiflora caerulea L., P. alata Curtis and incarnata L. (synonym for edulis Sims), are the most popular representatives of genus in South America. In recent years, a growing attention is paid to biological activity phytochemical profiles crude extracts from various species worldwide. The aim this study was evaluate compare anti-leukemic dry leaves three greenhouse Poland two human acute lymphoblastic leukemia cell lines: CCRF-CEM its multidrug resistant variant. Two systems liquid...
Twenty-nine flavonoid glycosides were identified in the aqueous extract (PC) of <italic>Petroselinum crispum</italic> var. <italic>crispum</italic> leaves and apiin, major compound, was isolated thereof.
Silver nanoparticles are widely used in industry, medicine, biotechnology and agriculture. As a consequence, these reaching the environment as waste products, which might have negative impact on environment, especially plants. This includes elicitation of various biochemical processes In this article, we report changes secondary metabolic profile Arabidopsis thaliana seedlings subjected to silver nanoparticle treatment vitro. Briefly, sizes (10 nm, 40 nm 100 diameter) concentrations (0.5–5.0...
Trees of the Annona species that grow in tropics and subtropics contain compounds are highly valuable for pharmacological research medication development have anticancer, antioxidant, migratory properties. Metabolomics was used to functionally characterize natural products distinguish differences between varieties. Natural therefore bioactive-marked respected field drug innovation. Our study aimed evaluate interrelationships among six species. By utilizing Start Codon Targeted (SCoT) Inter...
Structural analysis via HPLC-ESI-MSn, UPLC-HESI-MS/MS and NMR reported 152 phenolic secondary metabolites in spring barley seedlings (Hordeum vulgare L.). Flavonoids with various patterns of glycosylation acylation, as well hydroxycinnamic acid glycosides, esters amides, were identified methanolic extracts from leaves nine varieties originating different regions the world. Hordatines derivatives, flavones acylated directly on aglycone, hydroxyferulic derivatives deserve special attention....
Melissa officinalis (MO, English: lemon balm, Lamiaceae), one of the oldest and still most popular aromatic medicinal plants, is used in phytomedicine for prevention treatment nervous disturbances. The aim our study was to assess effect subchronic (28-fold) administration a 50% ethanol extract MO leaves (200 mg/kg, p.o.) compared with rosmarinic acid (RA, 10 huperzine A (HU, 0.5 on behavioral cognitive responses scopolamine-induced rats. results were linked acetylcholinesterase (AChE),...
Sinapic acid and its derivatives are main phenolic compounds present in rapeseed. Identification quantitative determination of those were carried out crude extracts as well after basic acidic hydrolysis. The total content the extracts, expressed sinapic equivalent, ranged from 1577 to 1705 mg/100 g for cv . Visby Bellevue, respectively. An increase phenolics contents was observed hydrolysis comparison extracts. predominant acids rapeseed samples trans ‐sinapic cis acids. highest...
Plant interactions with environmental factors cause changes in the metabolism and regulation of biochemical physiological processes. defense against pathogenic microorganisms depends on an innate immunity system that is activated as a result infection. There are two mechanisms triggering this system: basal perception microbe-associated molecular patterns through pattern recognition receptors situated cell surface effector-triggered (ETI). An induced biosynthesis bioactive secondary...
The study describes isolation and semi‐preparative HPLC scale purification of plastochromanol‐8 (PC‐8). PC‐8 standard was obtained from flaxseed oil. purity the 93.06% determined by UV–Vis detection. HPLC/MS n fragmentation pattern side chain resulted in successive release eight isoprene fragments which confirmed correct structure identification. established molar absorption coefficient (3616.5 M −1 cm ) will allow precise quantitative analysis this compound real samples without use a...
Fusarium proliferatum and F. verticillioides are considered as minor pathogens of pea (Pisum sativum L.). Both species can survive in seed material without visible disease symptoms, but still contaminating it with fumonisins. Two populations pea-derived strains were subjected to FUM1 sequence divergence analysis, forming a distinct group when compared the collection originating from different host species. Furthermore, mycotoxigenic abilities those evaluated on basis planta vitro fumonisin...
