ABSTRACT

Aspectos farmacognósticos de Croton rhamnifolius H.B.K. e C. rhamnifolioides Pax & Hoffm. foram comparados. Evocou-se a armacogeografia do gênero em Pernambuco, bem como a farmacoetimologia, farmacoetnologia, farmacobotânica e a farmacoquímica das espécies citadas. Este estudo permitiu localizar os taxa nesse Estado, conhecer seus nomes vulgares e suas utilizações, segundo a população local. Comparou-se também as características botânicas e finalizou-se com um estudo fitoquímico, que evidenciou os protocolos extrativos, e a caracterização dos principais grupos de substância presentes nos dois taxa: polifenóis, terpenóides, alcalóides e açúcares redutores.


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.
