, (2008/06/13)
An excellent fragrance compound having high palatability. A 3-(3-hexenyl)-2-cyclopentenone represented by a general formula (1) (wherein wavy line represents a double bond cis-form and/or trans-form) is used as an active ingredient of scent and mixed in a small amount with fragrance compositions, cis-jasmone and/or various materials to be scented. Since the above compound has a characteristic fragrance quality and high palatability, it is markedly useful as a scenting component of various fragrances and cosmetics, sanitation materials and the like.
