Fragrant rug found in ruins of Cairo (8)
I believe the answer is:
aromatic
'fragrant' is the definition.
('aromatic' can be similar in meaning to 'fragrant')
'rug found in ruins of cairo' is the wordplay.
'rug' becomes 'mat' (I've seen this before).
'found in' indicates putting letters inside.
'ruins of' indicates anagramming the letters.
'cairo' anagrammed gives 'aroic'.
'mat' placed within 'aroic' is 'AROMATIC'.
(Other definitions for aromatic that I've seen before include "Sweet-scented" , "Actor am I with nice smell" , "Perfumed" , "with fragrant quality" , "Scented" .)
