Abstract

Two new oligomeric proanthocyanidin glucosides were isolated from the aerial part and roots of Alhagi pseudalhagi. Their structures and relative configurations were elucidated as 7-O-β-D-Glc p 6 galloyl-(+) catechin-(4α-8)-(+)-catechin-(4α-8)-(–)-epigallocatechin and 7-O- β-D-Glc p 6 galloyl-(+)-catechin-(4α-8)-(+)-catechin 3-(4α-8)-(–)-epigallocatechin-3-O- gallate.
