title: Polyacetylene glycosides from Pratia nummularia cultures.
abstract: Two polyacetylene glycosides, lobetyol 9-O-glc(6)-(1)rha (pratialin-A) and lobetyol 9-O-glc(6)-(1)glc(6)-(1)glc (pratialin-B), were isolated from Pratia nummularia (Campanulaceae) callus and hairy root cultures and their chemical structures were determined by analysis of spectroscopic data. From the methanol extract of the hairy root cultures, together with the known polyacetylene constituents lobetyol, lobetyolin, and lobetyolinin, tryptophan was also isolated. This report is the first example of the isolation and structure elucidation of rutinoside (pratialin-A) and triglucoside (pratialin-B) derivatives of polyacetylene constituents.
