Assuming that I understand what you want to do (that is, removing all
the packages that came from an non-official mirror) then the "Packages"
file that comes from any mirror are your friends.
For finding 'em, try:
% ls /var/lib/apt/lists/*Packages
then, detect the file that is related to the mirror that you want to
remove packages coming from it.
Let's use for example Christian Marillat's debian-multimedia.org mirror.
/var/lib/apt/lists/www.debian-multimedia.org_dists_sid_main_binary-i386_Packages
Say that you want to remove all the packages coming from that mirror.
Then, what you should do is:
# apt-get remove --purge `cat
/var/lib/apt/lists/www.debian-multimedia.org_dists_sid_main_binary-i386_Packages
|grep ^Package | awk '{print $2}' |xargs`
I hope that I did get what you wanted to do, and that his would solve
your problem.
