Dig up assorted red tins containing iodine (8)
I believe the answer is:
disinter
'dig up' is the definition.
(disinterring is a kind of digging up)
'assorted red tins containing iodine' is the wordplay.
'assorted' indicates an anagram.
'containing' means one lot of letters goes inside another.
'iodine' becomes 'I' (I is the chemical symbol for iodine).
'red'+'tins'='redtins'
'redtins' is an anagram of 'disnter'.
'disnter' enclosing 'i' is 'DISINTER'.
(Other definitions for disinter that I've seen before include "Exhume a body" , "Bring up" , "Dig up something buried" , "Dig up a dead body" , "Dig up, say a body" .)
