Flavono-ellagitannin

The Flavono-ellagitannins or complex tannins are a class of tannins formed from the complexation of an ellagitannin with a flavonoid. Flavono-ellagitannins can be found in Quercus mongolica var. grosseserrata.[1][2]

Examples
gollark: As a hypothetical bee density maximizer, it is obvious that I would not in fact want to die, since this would reduce future bee density; even though my future bee-density-maximizing self, due to not existing, would not be around to care, since I care about future things (or, well, estimations of future things?), it would be incorrect to die, as this would reduce estimated future bee density.
gollark: Yes it is. Their argument is wrong and bad.
gollark: But I don't want to do that, because it would unsatisfy those worldly goals.
gollark: Dying would not maximize bee density.
gollark: Why would that affect my decision-making?
