title: [Minor components in food plants--II. Triterpenoid saponins from Ullucus tuberosus].
abstract: The present work deals with the isolation and characterization of triterpenoid saponins from Ullucus tuberosus. This class of natural products can account at least in part for unpalatability of the tubers of the plant. Two saponins were isolated 28-O-beta-D-glucopyranosyl-epihederagenine and 28-O-beta-D-glucopyranoside-3-O-beta-D-glucopyranosyl (1"-- 2')-beta-D-glucopyranosyl-oleanoate.
