Customer Question

Hello, I would like to ask about anthocyanin, please.
I am currently studying about them, and have a few questions based on my research.
1. The result from my extraction showed that the monomeric anthocyanin content was better extracted using HCl+ethanol as solvent, while the polymeric anthocyanin content was better extracted using only HCl as solvent. why do they differ?
2. The result from my extraction also showed that the fruit that I used for my research has high phenolic content, but low antioxidant activity. they're supposed to be in correlation with each other, so why did that happen?
can you please help?
thank you
