Sorry, no etymologies found.
Research done in recent years in our labs has showed that certain compounds in food, notably the blueberry's delphinidin, green tea's EGCG or the ellagic acid found in strawberries have the ability to impede the formation of these new vessels by blocking the activity of VEGFR-2, a protein essential to the angiogenesis process.
Working with the Australian company Florigene the researchers took the delphinidin gene, which creates the blue colour, from a petunia.
"High degradation rates of malvidin arabinoside and delphinidin arabinoside suggest that they may be highly susceptible to destruction and less suitable for food colourant use among those tested," they concluded.
When the stability of the individual anthocyanins was analysed, cyanindin glucoside was the most stable, followed by peonidin, petunidin, malvidin, and delphinidin.
