[M⁻ H]⁻ 577 m/z
MS²⁻ 289 m/z
STD
True
TLC
False
UV/Vis detector description

Mass spectrometer description
UPLC-PDA-ESI-MS/MS, UPLC-QTOF-MS
Organism
Aronia melanocarpa 'Galicjanka'
cultivated
ground, dried, passed through a strainer (1mm)
Sample note
The fruit samples (about 15kg) were obtained from a horticultural farm in Trzebnica, near Wroclaw, Poland. The raw material was collected at the optimum ripening stage recommended for consumption. The whole fruits were freeze-dried, so that the pressure was reduced to 0.0960 kPa. The temperature in the drying chamber was -60 C, and in the shelves 26C. The dried material was ground with laboratory mill (IKA A.11, Christ) and then passed through a strainer (1mm). The powder (code PDF) was ready for the analyses.

Sample note
The fruit samples (about 15kg) were obtained from a horticultural farm in Trzebnica, near Wroclaw, Poland. The raw material was collected at the optimum ripening stage recommended for consumption. The whole, uncrushed fruits were pressed on a hydraulic press (SSRE, Waesaw, Poland). The obtained pomace was freeze-dried using an Alpha 1-4 LSC freeze dryer. The pressure was reduced to 0.960kPa. The temperature in the drying chamber was -60 C, and in the shelves 26C.Then, the material was ground, then passed through a strainer (1mm). After that the powder (code PPUF) was ready for the analyses.
