Hi,
Please tell me the better reducing reagent for the reduction of heterocyclic oxime to amine.

Without first knowing what the heteroccle main structure is and any extra (reduction sensitive?) functionalities present in your molecule of interest I would propose:

LiAlH₄
Zn/AcOH
NaOEt, or formed in situ from Na + EtOH
BH₃
maybe NaBH₄
H₂/(Pd/Pt/Rh?) catalytic hydrogenation

And enantioselectively using baker's yeast as one possibility.
