is it true that n-oxide of amine compound will form in trace amount while using ether solvent?

Depends which amine.  I doubt all do or I would not need to use hypofluorous acid to generate some oxides.

Depends on how much peroxide is present in the ether solvent.

my compound have trace amount of n-oxide which is form while i am doing workup in ether solvent, by doing repeated crystallization the n-oxide not wash out completelly,which is best method to remove n-oxide from organic compound ??

[discodermolide]

try a reductive work-up. or better do not use an etheric solvent

Use distilled ether and you may not see the oxidation product.
