If you mean pure pyrogallol (1,2,3‑trihydroxybenzene), its formula is C6H6O3, so the elements present are carbon (C), hydrogen (H) and oxygen (O).

If you mean the reagent called "alkaline pyrogallol" (pyrogallol dissolved in alkali to make it strongly basic, e.g. KOH solution used to absorb O2), then the mixture also contains the alkali metal (typically potassium, K, from KOH — or sodium, Na, if NaOH is used) and usually water. So the elements in that reagent are C, H, O and K (or Na).
