Changes in the composition of the polar fraction of Persian lime ( Citrus latifolia ) during fruit growth by LC–QTOF MS/MS analysis

GC‐MS study of changes in polar/mid‐polar and volatile compounds in Persian lime (Citrus latifolia) during fruit growth

“…They suggested that the decrease in the concentration of citric acid at the final ripening stage could be due to sequential metabolism to isocitric acid, 2‐oxoglutaric acid and glutamic acid. The behavior of carboxylic acids was very similar to that reported recently by Ledesma‐Escobar et al . on the major phenolic compounds in Persian limes, the maximum concentration of which occurs in the last 3 weeks of the maturation process.…”

“…The GC‐MS analyses developed in this study allowed tentative identification of coumarins such as sphondin, psoralen, isopimpinellin and 7‐nitro‐3,4‐benzocumarin, which had not been identified from the MS/MS information obtained by LC‐QTOF‐MS/MS in our previous study . Probably the use of chloroform in the extraction step prior to GC‐MS analysis favors the extraction of this type of compound, as does 7‐nitro‐3,4‐benzocumarin, which was not found in the LC‐MS/MS databases used in our previous study.…”

“…Changes in polar compounds during Persian lime growth have recently been studied by the authors in both targeted and untargeted analyses, using liquid chromatography–triple‐quadrupole tandem mass spectrometry (LC‐QqQ MS/MS) and liquid chromatography–quadrupole time‐of‐flight tandem mass spectrometry (LC‐QTOF MS/MS), respectively. The present research was aimed at complementing our previous study and expanding the knowledge on changes in metabolite abundance during Persian lime growth and maturation from week 1 after fruit onset to week 14 . With this aim, the profiles of volatile and polar compounds were obtained by gas chromatography–mass spectrometry (GC‐MS) combining headspace solid‐phase microextraction (HS‐SPME) and direct GC‐MS analysis of derivatized extracts, respectively.…”

“…Changes in polar compounds during Persian lime growth have recently been studied by the authors in both targeted 10 and untargeted 15 analyses, using liquid chromatographytriple-quadrupole tandem mass spectrometry (LC-QqQ MS/MS) and liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (LC-QTOF MS/MS), respectively. The present research was aimed at complementing our previous study and expanding the knowledge on changes in metabolite abundance during Persian lime growth and maturation from week 1 after fruit onset to week 14.…”

“…The present research was aimed at complementing our previous study and expanding the knowledge on changes in metabolite abundance during Persian lime growth and maturation from week 1 after fruit onset to week 14. 10,15 With this aim, the profiles of volatile and polar compounds were obtained by gas chromatography-mass spectrometry (GC-MS) combining headspace solid-phase microextraction (HS-SPME) and direct GC-MS analysis of derivatized extracts, respectively. The results of this study could also provide a comprehensive exploitation of citrus by finding alternatives to fresh fruit commercialization, mainly in seasons with overproduction or when the quality of the fruit is not sufficient for the fresh fruit market.…”
