neroli

I'm a little stuck... Click here to teach me more about this clue!

'oil extract' is the definition.
'neroli' can be an answer for 'oil' (I've seen this before). I'm not sure about the 'extract' bit.

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for neroli that I've seen before include "Product of orange-blossom" , "Orange flower oil" , "Nil ore (anag.)" , "sort of oil" .)

I've seen this clue in the Sydney Morning Herald.
