The present invention pertains to a lactone compound represented by general formula (A), and an ether compound represented by general formula (B). [In formula (A), R is a hydrogen atom or R1, R' is R1 if R is a hydrogen atom, carbon bond (1) is a single bond or a double bond, and carbon bond (2) is a single bond. If R is R1, then R' is a hydrogen atom or R1, and, among the carbon bonds (1) and (2), both are single bonds, or one is a double bond and the other is a single bond. In formula (B), R'' is R1. R1: an optionally-substituted C1‑8 alkyl group, an optionally-substituted C2‑8 alkenyl group, an optionally-substituted C2‑8 alkynyl group, or an aryl group. In formula (A) and formula (B), n is 0 or 1.] |
