You cant, as you can set the anchor to anything.
Why do you need that information? Most of the time you can simply work around it using the bounds.

 ;)   so quickly reply!!!

I want to  add a cube to the left of the tk2dSprite, if the Anchor  is middle center, then i add like this:
  cube = new cube;
  cube . x = transform.position.x  - bound.x / 2f;

 if the Anchor  is low leftr, then the cube. x should be   transform.position.x;

Ah but thats the point you don't need to know what the anchor is.

Bounds b = sprite.GetUntrimmedBounds();
cube.position = sprite.transform.position + b.center - b.size * 0.5f; // lower left
Or something like that.
