If you have only had your kitten for one night, i dont see how you could have carried out the introduction procedure as this process is over a week. This gives the cats time to get to know each other in a safe environment.
Also you say your cat is not neutered. This will naturally make him more aggressive and territorial.
Your big cat may feel threatened by the presence of the new kitten and this could be why he is anxious and is not eating. Having him neutered and the kitten too when he is old enough is a good starting place to having cats that can live together.
Cats especially un neutered cats are very territorial, this is what drives them and their behavior. I really think you should consider neutering your cats. I'm not sure why you have not so far so i have attached a link to a page about neutering which lots of information about the benefits and the process etc.
