“…The extract also contained the acetyl derivative of the peonidin hexoside (5). The ion at m/z 505 gave the MS 2 fragment ion at m/z 301, identifiable in peonidin aglycone [23]. The loss of a 204 (42+162) Da residue allowed us to hypothesize the presence of an acetylhexoside moiety.…”

In order to promote breeding programs and a full reintroduction into production of two local red-fleshed apple varieties grown in Bekran and Bastam (Iran), the evaluation of their antioxidant properties was of interest. LC-MS(n) based metabolic fingerprinting analyses were applied to investigate the anthocyanin content of both peel and flesh components of the fruits. Cyanidin-3-O-hexoside isomers were present in both 'Bekran' and 'Bastam' apples, whereas 'Bekran' apple was a valuable source of anthocyanin rutinose derivatives. Employing DPPH(•), ABTS(•+), and ORAC methods, the antiradical efficacy was evaluated. The ability of the investigated fruit components to scavenge OH(•), and O(2) (•-) reactive species was also assessed. ID(50) values highlighted the massive antioxidant response of 'Bekran' peel component, able to counteract by 50 % OH(•), and O(2) (•-) at 130.3 and 91.6 μg/mL, respectively. The cytoprotective screening towards HeLa, HepG2, A549, SH-5YSY, and SK-N-BE(2)-C cell lines evidenced that the investigated Iranian red-fleshed apple fruits were able to exert a significant antioxidant response in hydrogen peroxide oxidized cell systems. Data collected suggested that the revaluation of 'Bekran' and 'Bastam' apple cultivars could represent a precious source of antioxidant compounds whose dietary intake could improve the human well-being reducing risks of free radical related chronic and degenerative diseases.

“…The CHCA-SA mixture has a main ion at about 414 Da that was removed from the MALDI-TOF mass spectrum in order to highlight anthocyanins signals profiles were acquired; ion gate has been set to corresponding mass range of the each compound mass, as given in Table 5, to allow the anthocyanins aglycon characterisation. The fragmentation of 531, 573 and 677 ions generated a common fragment (369) that derived from carboxy-pyrano compounds, this being reported even by Stefova and Ivanova (2011). In the MALDI-TOF mass spectrum of the samples was noticed the presence of Vitisin A (561 Da) and Vitisin B (517 Da); the 399 and 355 fragment ions are also due to the pyranoderivatives (Flamini and Traldi 2010).…”

“…The identification of the anthocyanidins and anthocyanins occurring in the analysed samples were per- Fig. 4), and compared to other published data (He et al 2012;Castañeda-Ovando et al 2012;Ivanova et al 2011;Grant and Helleur 2008;Stefova and Ivanova 2011) that confirmed the ascription of the fragments.…”

“…Contemporary research utilises approaches that are based on MS techniques. The MS technique has the advantage of being more accurate and efficient in the identification of anthocyanins (Castañeda-Ovando et al 2012;Ivanova et al 2011;Grant and Helleur 2008;Stefova and Ivanova 2011) Matrixassisted laser desorption/ionisation-time of flight (MALDI-TOF) is a mass spectrometry technique that prevents the unwanted fragmentation of the molecules and can be used for analysis of complex mixture without prior separation.…”

Phenolic and Anthocyanin Profile of Valea Calugareasca Red Wines by HPLC-PDA-MS and MALDI-TOF Analysis

et al. 2015

The quality of red wines is given by phenolic compounds and anthocyanins and is associated with colour, taste and therapeutic effects on human health. This work aims to provide a detailed profile of phenolic compounds and anthocyanins that are found in five red wine samples from Dealu Mare-Valea Calugareasca region. The phenolic and anthocyanin profiles of the red wine samples were determined by high-performance liquid chromatography-photodiode arraymass spectrometry and matrix-assisted laser desorption/ ionisation-time of flight, respectively. The results obtained showed that Feteasca Neagra had the highest content of phenolic compounds followed by Pinot Noir while the preponderant compound was gallic acid. Amongst anthocyanins, malvidin was found to be the major compound and the highest anthocyanin content was found also for Feteasca Neagra wine. A simple high-performance liquid chromatographyphotodiode array-mass spectrometry method was developed, optimised and applied for the quantification of phenolic compounds in red wine samples from Dealu Mare-Valea Calugareasca region. In the same time, a rapid matrixassisted laser desorption/ionisation-time of flight method that does not need sample preparation was applied for the identification of anthocyanins. Moreover, the phenolic and anthocyanin composition of red wines from Dealu Mare-Valea Calugareasca region is reported for the first time. The phenolic and anthocyanin profile determination will be beneficial for the Romanian winemakers to produce high-quality red wines.

“…MS data were assigned to metabolites on the basis of accurate mass, isotopic distribution and fragmentation pattern in both positive and negative ion modes. Assignments were confirmed after comparison with literature data (see for instance Cantos, Espín, & Tomás-Barberán, 2002;Cavaliere et al, 2008;Cejudo-Bastante, Pérez-Coello, & Hermosín-Gutiérrez, 2010;Flamini, 2013;Guerrero et al, 2009;Gómez-Romero, Segura-Carretero, & Fernández-Gutiérrez, 2010;Kajdžanoska, Gjamovski, & Stefova, 2010;Kneknopoulos, Skouroumounis, Hayasaka, & Taylor, 2011;Rodríguez-Medina, Segura-Carretero, & Fernández-Gutiérrez, 2009;Sonni et al, 2011;Stalmach, Edwards, Wightman, & Crozier, 2011;Stefova & Ivanova, 2011) and with on-line public metabolite databases (PubChem <http://pubchem. ncbi.nlm.nih.gov/>, Metlin <http://metlin.scripps.edu/> and Chemspider <http://www.chemspider.com>).…”
