Abstract

Fifteen constituents, including a new compound, were isolated from an ethanolic extract of the peel of Citrus kawachiensis Hort. ex. Y. Tanaka (Japanese brand name, kawachibankan) which is one of the citrus products specific to Ehime, Japan. The new compound was characterized as 4'-dihydrophaseic acid β-glucopyranose ester (15) on the basis of spectral and chemical evidence.
