Re: HYB: pigments: anthocyanic vacuolar inclusions

Thanks Chuck for posting that interesting abstract.

Stuff I don't quite understand:
They mention AVI's in the <vacuoles of the petal epidermis>, then later
mention isolating AVI's <from the inner region of lisianthus
petals> and <they consist of a protein:anthocyanin
complex to which only a subset of the anthocyanins and flavonoids
produced in these [inner?] tissues is bound.>

Back to my old question about layers of cells in the petal and
distribution of pigments.  If I understand what they are saying,
anthocyanins are present in more than one layer of petal cells (at least
in Lisianthus), and they occur in <both> the watery cell sap and the
oily vacuoles.

Does the rest of the article say whether or not those
protein:anthocyanin complexes can be extracted from the petals with
water/alcohol?  Or maybe acetone?

Or ..?
