Purple tomato leaf anthocyanins

Had some old leaves looking sad on a purple tomato plant, very little green, purple showing especially bottom.
Crushed some up in a little 70% ethanol, one batch with a pinch of citric acid to acidify.
Ran TLC plate with 8:1:1 ea:water:vinegar, but the pigments mostly stayed put. Some other fluorescent stuff moved though.
Tried paper with acetone (+water & vinegar) and with IPA (70%, with a drop or two of vinegar) without nice results on either, could tweak if I cared, the IPA carried it too well and it stayed at the front.
Coolest thing is the color diff acidified vs not.
Also squished a leaf into a leaf print in my physical lab notebook.
Single indoor tomato is ~2cm across, outdoor plant has 5 flowers starting :D
