Comparative characterization of phenolic and other polar compounds in Spanish melon cultivars by using high-performance liquid chromatography coupled to electrospray ionization quadrupole-time of flight mass spectrometry

Chemical fingerprint and bioactivity evaluation of Globularia orientalis L. and Globularia trichosantha Fisch. & C. A. Mey. using non‐targeted HPLC‐ESI‐QTOF‐MS approach

“…Likewise, peak 3 was found in G. trichosantha and G. orientalis . Its characterisation as sucrose was based on the presence of the fragments at m / z 101 and 113, as reported by Rodríguez‐Pérez et al . Additionally, the trisaccharide tentatively characterised as raffinose was only found in the G. trichosantha .…”

“…Likewise, peak 3 was found in G. trichosantha and G. orientalis. Its characterisation as sucrose was based on the presence of the fragments at m/z 101 and 113, as reported by Rodríguez-Pérez et al49 Additionally, the trisaccharide tentatively characterised as raffinose was only found in the G.trichosantha. That compound presented three main fragments at m/z 221, 179 and 161 and the characterisation was made based on the MS data and comparing the fragments with the Metlin database.…”

In vitro simulated digestion and in vivo metabolism of chlorogenic acid dimer from Gynura procumbens (Lour.) Merr.: Enhanced antioxidant activity and different metabolites of blood and urine

“…Peak 1 was characterized as phloroglucinol glucuronide, based on accurate results of phloroglucinol glucuronide identified from hydro‐methanolic extract of watermelon by accurate‐MS (Ibrahim, Arráez‐Román, Segura‐Carretero, & Fernández‐Gutiérrez, ). Peak 2 was inferred as tryptophan, which confirmed to Rodríguez‐Pérez C's report that precursor and fragment ion of tryptophan identified from phenolic in Spanish melon cultivars was m/z 203 and 116, too (Rodríguez‐Pérez, Quirantes‐Piné, Fernández‐Gutiérrez, & Segura‐Carretero, ). Peak 3 and Peak 4 were identified as shikimic acid 1,8‐cineole‐2‐ O ‐β‐α‐glucopyranoside, respectively by matching data in the literatures (Liang et al, ; Rodríguezpérez et al, ).…”

“…Peak 11 was identified as dicaffeoylshikimic acid, consistent with the identification of phenolic acid derivatives and flavonoids from Helichrysum obconicum (Gouveia & Castilho, 2011). Peak 12, 13 and 15 were identified as methylquercetin glucuronide, benzyl alcohol hexose-pentose and salvianolic acid A by comparing with previous studies, respectively (Peng et al, 2011;Rodríguez-Pérez et al, 2013;Ye et al, 2014). Peak 17 was deduced as galloyl-glucoside consistent with the identification of major derivatives of ellagic acid (Rodríguezpérez et al, 2013;Sun et al, 2015).…”

Aroma volatiles obtained at harvest by HS‐SPME/GC‐MS and INDEX/MS‐E‐nose fingerprint discriminate climacteric behaviour in melon fruit

“…Fruits with climacteric behaviour have a short shelf‐life and higher aroma levels than non‐climacteric fruit, because some aroma compounds are produced almost exclusively by ethylene‐dependent pathways . In climacteric genotypes, the volatiles reported are mostly esters and sulfur‐derived ester compounds . On the other hand, non‐climacteric melons show lower levels of aroma volatiles mostly saturated and non‐saturated C 9 alcohols and aldehydes with a lack of sesquiterpenes and esters or, at least, lower levels of detection of the same …”
