Abstract

The root of Actinidia arguta was extracted with methanol and the methanol extract was suspended in $H_2O$ and successively partitioned with n-hexane, $CH_2Cl_2$, EtOAc and n-BuOH. Repeated column chromatographic separation of the EtOAc extract resulted in the isolation of two flavonoids (compounds 2 and 3) and two triterpenes (compounds 1 and 4) and $CH_2Cl_2$, extract to afford three lignans (compounds 5-7). Their structures have been established by spectroscopic, means to be (+)-tormentoside(1), (-)-catechin(2), (-)-epicatechin(3), (+)-uscaphic $acid-28-O-[\beta}-D-glucopyranoside$(4), (+)-pinoresinol(5), (+)-medioresinol(6), and (-)-syringaresinol(7).
