2'-Hydroxy-4'-methoxyacetophenone (Paeonol) in Exacum affine cv.

Abstract

Since the lesioned part of the Exacum affine cv. plant showed remarkable insect attractivity to males of the giant danaid butterfly, Idea leuconoe, the volatile components of E. affine cv. were analyzed. The main component in every part was identitied as 2'-hydroxy-4'-methoxyacetophenone (paeonol), and authentic paeonol crystals showed similar insect attractivity.
