The present study aimed to use methods to perform the quality control of some vegetal drugs based on Bauhinia forficata from Itajaí and Balneário Camboriú, using the flavonoid kaempferitrin as chemical marker. The methods used were thin layer chromatography (TLC) and high performance liquid chromatography (HPLC), besides microscopic analysis, label analysis and organoleptic characteristics and strange material presence. All the analyses were compared with the authentic sample of B. forficata (A) results. This study used six commercial samples which were denoted as B-G. In the strange material analyses, all the samples were disapproved because they were above 2%. Microscopic analyses revealed that only B and G samples were identical to B. forficata (A). The chromatographic results suggested that only the samples B, C, E and G presented kaempferitrin.
