Constituents of Japanese Peppermint Oil

Part III. Isolation and Identification of Two New Constituents from “Shubi”

Abstract

Isopentyl isovalerate and anisic acid were first isolated and identified from the Japanese peppermint oil. The former compound possesses characteristic apple-like oder. α-Bour-bonene, menthofurolactone, and β-caryophyllene epoxide were also isolated and identified from the oil of Shubi, a newly registered Japanese peppermint.
