I am assuming you are referring to the scientific name for a pineapple. Which would be Ananas comosus. The pineapple belongs to the Bromeliaceae family of plants. Botany simply differentiates the pineapple plant from its culinary uses.
The word 'ananas' is masculine therefore if you were sayin 'i would like one pineapple' you would simply say "je voudrais un ananas" not une ananas but unananas
The scientific name would be Ananas comosus.
