Genetic diversity among genotypes of Uncaria guianensis (Aubl.) J.F. Gmel. maintained in an in vitro germplasm bank.

ABSTRACT: Phytotherapeutic preparations from Uncaria guianensis (Aubl.) J.F. Gmel. (Rubiaceae) are marketed worldwide and are mainly used for their anti-inflammatory activity. The species has not yet been domesticated and is threatened by deforestation and overexploitation. It is, therefore, important to preserve and manage this genetic resource in germplasm banks, so that the extractive provision of plant material can be replaced by cultivated production. The aim of this study was to evaluate the genetic diversity among 20 genotypes maintained under in vitro conditions using 9 primers start codon targeted (SCoT) polymorphism, and to determine the concentrations of the pentacyclic oxindole alkaloids (POAs); mitraphylline and isomitraphylline in methanolic extracts by high-performance liquid c
