Water-soluble constituents of Glehnia littoralis fruit

Abstract

From the water-soluble portion of the methanol extract of the fruit of Glehnia littoralis Fr. Schmidt ex Miq. (Umbelliferae; "hamabōfu" in Japanese), thirty compounds, including three new monoterpenoids and a new monoterpenoid glucoside, a new benzofuran glucoside, a new alkyl glucoside, and a new glucide, were obtained. Their structures were clarified by spectral investigation.
