try HPLC MS MS

The simplest identification of phenolic compounds is through the ferric chloride test. You take little sample & add the yellow FeCl3 solution to it.If there is phenolic group, then a blue-violet color will be observed (in many cases) but colors such as purple, green, or red-brown were also detected. There is a reaction which forms a complex as the equation shows:

3ArOH + FeCl3 → Fe(OAr)3 + 3HCl

Adding few drops of 1% FeCl3(aq) is sufficient.

Yes HPLC-MS/MS. You can use phenolic compounds standard if you know what are the compounds you expecting.

Yes LC-MS with standards will work.
