چکیده
As frações solúveis em hexano dos rizomas ou das folhas de cinco espécies do gênero Dorstenia (Moraceae) (D. bahiensis Kl., D. bryoniifolia Mart ex. Miq., D. carautae C.C.Berg., D. cayapiaa Vell. e D. heringerii Car. & Val.) foram analisadas por HRGC-MS (cromatografia gasosa de alta resolução acoplada a espectrometria de massas). Foram identificados triterpenos pentacíclicos, esteróides e furocumarinas. HRGC-MS mostrou ser uma ferramenta valiosa para a análise dos terpenóides de Dorstenia spp. Estas substâncias podem estar ligadas à utilização tradicional de Dorstenia spp. como plantas anti-ofídicas.
