The pharmacognostical aspects of Croton rhamnifolius H.B.K. and C. rhamnifolioides Pax & Hoffm. have been compared. The parameters applied for such comparison were the pharmacogeography concerning this genus in Pernambuco, as well as the pharmacoetymology, the pharmacoethnology, the pharmacobotany and the pharmacochemistry, all of which related to both species above mentioned. Not only was the present study able to ascertain the species’ rate regarding the State, but also to determine its medical usage and denomination among the locals. The botanical characteristics were compared and a phytochemical analysis was carried out in order to establish the extractive rocedures and also the main molecule’s rate found on both: terpenoids, alkaloids, polyphenols and reducting sugars.
