I have a compound of which 1H-NMR spectra was recorded (in Methanol-d4) as in the attached file. I can see some similarities to simple phenolic glycosides, but I'm not sure about that. I would like to know predictions for the structure of this compound.
P/S: No other peaks were obtained outside the chemical shift range shown in the attached spectra.
What a shame that you ran this in d4MeOH - you have lost all the exchangeable signals. This would have been much better in d6DMSO so you could have seen the hydroxyls and their splittings.
Without other data it is almost impossible to come up with a putative structure for this (unless it matches a known material). It looks very much like a glycoside. The anomeric proton is very deshielded. I think that you need a mass spec (to understand what we are dealing with) and probably HSQC and HMBC.
