RE: HYB: leaf pigment extraction


I took a good number of photos of Purple based foliage. All the ones appearing red looked much more purple once the leaf was rubbed, removing the  white coating on the leaves. This white coating is much heavier on some plants then others. I havn't done any extraction but have assumed it is anthocyanin as this same phenomenen appears on many different species. There is a fair bit of reseacrch on it, all in plants other iris. It makes for interesting reading. I ran accross one today while looking for something else. It was about the amount of anthocyanin (its always anthocyanin) in a plant (tomatoes leaves I think, but not positive as I just glanced at it long enough to know it wasn't what  I was looking for at the time). They were measuring amount of anthocyanin as a relationship to exposure to sunlight. 
Key words for an internet search would be anthocyanin, leafs, foliage sunlight, etc. One of the current theories that seems to be receiving suport is that it protects plants that are normally found in high altitudes and it protects from ultraviolet light which could damage cells esepecially in newly germinated plants.

Subject: [iris] HYB: leaf pigment extraction

Has anyone tried extracting red pigments from the base of fans?

Is it water/alcohol soluble?  What color does it look in solution?
