New oligomeric proanthocyanidins from Alhagi pseudalhagi

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-Gl c galloyl-(+)catechin-(4α-8)-(+)-catechin-(4α-8)-(–)-epigallocatechin and 7- O -β-D-Glc galloyl-(+)-catechi...
