Abstract

The alkaloid and procyanidin composition of Uncaria sp. from eastern Peru, used in folk medicine was studied. Five alkaloids have been separated and identified as pteropodine, speciophylline, isopteropodine, uncarine F and isomytraphylline, all belonging to the oxindole group characteristic of the Rubiaceae. Moreover (--) epicatechin and four dimeric procyanidins A1, B1, B2 and B4 have been shown to constitute the polyphenolic fraction of the plant extract.
