Abstract

Fifteen samples commercialized as Pau-pereira have been purchased from open-air fairs, herbal stores, newsstands, and Internet sites, and their anatomical features were compared with two reference samples of Geissospermum laeve, Apocynaceae. In addition, an analysis was carried out to track the presence of flavopereirine, an alkaloid described in G. laeve and other species of the genus, in both ethanolic extract and infusions of the reference samples, as well as the 15 samples acquired from commercial sources.
