You should never abbreviate any quotation. An abbreviation would be, for example, using abbrev. instead of the word abbreviation that is used in the quotation.
If you mean how do you truncate an abbreviation, you should use only the portion of the abbreviation you need. To truncate means to shorten. So for example, let's use Abraham Lincoln's quote:
"Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal."
Let's say you only want to use the part about equality, you could write:
Although Abraham Lincoln stated that our nation was "...dedicated to the proposition that all men are created equal", this is not the reality of many Americans today.
