Abstract

In a continuation of investigations of proanthocyanidins of the roots ofRhodiola pamiroalaica, we have isolated proanthocyanidins RP-3 and RP-4. Their compositions, structures, and relative configurations have been investigated: RP-3 is 7-O-(6-O-galloyl-β-D-Glcp)-3-O-galloyl-(-)-epigallocatechin-(4β-8)-[(-)-epicatechin-(4β-8)-(3-O-galloyl-(-)-epigallocatechin)]2-(4β-8)-[5-O-(β-D-Glcp→O-β-D-Glcp)-(+)-catechin], and RP-4 is 7-O-(6-O-galloyl-β-D-Glcp-3-O-galloyl-(-)-epigallocatechin-(4β-8)-[3-O-galloyl-(-)-galloyl-5-(β-D-Glcp→O-β-D-Glcp)-(-)-epigallocatechin
