Fragrance composition

Abstract

A fragrance composition including a cis isomer and a trans isomer. The cis isomer includes a compound represented by formula (Ia), a compound represented by formula (Ib), a compound represented by formula (IIa), and a compound represented by formula (IIb), the trans isomer includes a compound represented by formula (IIIa), a compound represented by formula (IIIb), a compound represented by formula (IVa), and a compound represented by formula (IVb), and a mass ratio of the cis isomer to the trans isomer [cis isomer:trans isomer] is 65:35 or more and 95:5 or less. In the formulae (Ia), (Ib), (IIa), (IIb), (IIIa), (IIIb), (IVa), and (IVb), R1 is an alkyl group having 1 or more and 5 or less of carbon atoms, and R2 is a hydrogen atom or an alkyl group having 1 or more and 4 or less of carbon atoms.
