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.
本研究涉及从块根落葵薯中分离和鉴定三萜皂苷。这类天然产物至少在一定程度上导致了该植物块茎的不可口性。分离出了两种皂苷，28 - O - β - D - 吡喃葡萄糖基表异海得苷元和28 - O - β - D - 吡喃葡萄糖苷 - 3 - O - β - D - 吡喃葡萄糖基(1'' -- 2') - β - D - 吡喃葡萄糖基齐墩果酸酯。
