Chemical composition of white currant seed extract

Abstract

From the seeds of white currant (Ribes rubrum, cv. White Champagne), a new sesquiterpenoid glucoside (1) was isolated, along with two known compounds: dihydrophaseic acid 3’-O-β-Dglucopyranoside (2), and 3-carboxymethyl-indole-1-N-β-Dglucopyranoside (3). The structure of the new compound was identified as dihydrophaseic acid 3’-O-β-D-glucopyranosyl-1,6-β-D-glucopyranoside, based on extensive NMR and MS spectral studies.
