Hi,

I worked with extracts from oak, walnut and tropical woods (Jatoba and Padouk). The diversity of polyphenols and flavanoids is very big. Some compounds can be differed by the UV spectra, but not all. Therefore you should use MS detection to identify all compounds. To buy each standard is even more expensive.

I prefer PFP columns because of their higher polarity and selectivity, especially for phenolic compounds, compared to C18.
