Hello everyone,

I'm currently working with TLC plates stained with NP/PEG and I've noticed distinct yellow and green bands, indicating the presence of flavonoids. I understand that both colors generally signify the presence of flavonoids, but I'm curious if there is any information on whether the green bands might be associated with a specific type of flavonoid, and similarly, if the yellow bands correspond to another type of flavonoid.

Any insights or references on this matter would be greatly appreciated! Thanks in advance.
