As Lou has pointed out it may be worth a quick vet check up on her teeth /mouth to check all is okay there. If all is okay would suggest trying really strong smelling foods such as sardines/pilchards or tuna.

It is worth noting that our vet once told us (as we were concerned about one of our cats who just never seemed to eat much) that an egg cup of a good dried food is more than enough to maintain an average cat all day. She may just not be a big eater. Do you leave a bowl of dried food out for her all day? It may be she is a "grazer" - just having the odd nibble when she is feeling peckish.
