ABSTRACT

Partes aéreas do arbusto Hyptis fasciculata Benth. foram estudadas do ponto de vista químico. Após vários processos cromatográficos em coluna de gel de sílica, foi possível isolar um triterpeno livre (ácido betulínico), além de triterpenos em mistura (ácido ursólico com ácido betulínico e ácido ursólico com ácido oleanólico), esteróides em mistura (sitosterol e estigmasterol) e misturas de estigmasterol com ácido caféico e sitosterol com lignana. Tais substâncias foram identificadas por ressonância magnética nuclear de 1H e 13C.


The species Hyptis fasciculata Benth. is a shrub that is still unknown by the chemical point of view. This species has been studied in our group using their aerial parts. After many cromatographic processes over silica gel column, it was possible to isolate free triterpene (betulinic acid) and triterpenes in mixture (ursolic acid with betulinic acid and ursolic acid with oleanolic acid), one steroid mixture (sitosterol and stigmasterol) and a mixture of steroid with cafeic acid (stigmasterol and cafeic acid) and with lignan (sitosterol and sesamin). These compounds were identified by nuclear magnetic ressonance 1H and 13C.
