What the study found
UHPLC/Q-TOF analysis identified 35 anthocyanins across blueberry, raspberry, and two fungal-resistant red grape varieties. Only two anthocyanins were found in all three fruits: Cy 3-O-hexosides and Pn 3-O-hexosides.
Why the authors say this matters
The authors state that the findings increase knowledge of these varieties as potential sources of nutraceuticals and natural colorants. They also say the study expands the HR-MS/MS dataset useful for characterizing anthocyanins in other fruit varieties.
What the researchers tested
The researchers performed a comprehensive UHPLC/Q-TOF investigation of anthocyanins in three red-berry fruits: blueberry, raspberry, and two fungal-resistant red grape varieties. The abstract also notes earlier mass spectrometry approaches used for anthocyanin characterization, including direct-infusion ESI/IT-MS/MS and LC-Chip Q-TOF.
What worked and what didn't
The analysis found high levels of diglucosides in the grape berries. Raspberries contained Pg derivatives and several di- and trisaccharide anthocyanins, while blueberry uniquely accumulated Pn-malonylhexoside and arabinosyl anthocyanins.
What to keep in mind
The abstract does not describe experimental limitations or study constraints. The findings are limited to the fruits and anthocyanins named in the abstract.
Key points
- UHPLC/Q-TOF analysis identified 35 anthocyanins in blueberry, raspberry, and two fungal-resistant red grape varieties.
- Only two anthocyanins were shared by all three fruits: Cy 3-O-hexosides and Pn 3-O-hexosides.
- Grape berries showed high levels of diglucosides, while raspberries contained Pg derivatives and several di- and trisaccharide anthocyanins.
- Blueberry uniquely accumulated Pn-malonylhexoside and arabinosyl anthocyanins.
- Raspberry contained sophoroside and rutinoside anthocyanins only, and several compounds were characterized for the first time.
