Off the cuff, I don't know if there are any natural "oils" extracted from these fruits. A lot of my creations have fruit notes, but I create these accords through the use of different aromachemicals. Sometimes you can look at aroma profiles of different fruits and decide how to reconstitute the aroma using chemical isolates.
Fruit accords are really important to all kinds of fragrances. Even what seems like a citrus scent will often have a fruit component--like the mango component to Eau D'Orange Verte. You can use citrus peel oils, neroli, bergamot, and orange blossom to make a good citrus scent, but to really give a scent "flesh", it's nice to have some fruit accords at your disposal.
