Os extratos etanólicos das folhas e raízes de Combretum leprosum Mart. & Eicher (Combretaceae) foram investigados por CGAR-EM, após derivatização com BSTFA/ TMCS. Mono e oligossacarídeos, ácidos graxos e triterpenos foram identificados como componentes majoritários. Análise quantitativa por padronização externa revelou a presença de 65% de ácido arjunólico (1) no extrato etanólico das raízes secas. Foram observadas atividades anti-inflamatória, antinociceptiva e anticolinesterásicas (AChE e BuChE) para o extrato das raízes e para o ácido arjunólico, descortinando uma nova classe de produtos naturais no tratamento da doença de Alzheimer através de drogas multi- funcionais. Combretum leprosum Mart. & Eicher (Combretaceae) leaves and roots ethanolic extracts were investigated by HRGC-MS and showed mono- and oligosaccharides, fatty acids and triterpenes as major compounds after derivatization with BSTFA/ TMCS. Arjunolic acid (1) was quantified on dried roots ethanolic extract (65%) by external standard. Anti-inflammatory, antinociceptive and anticholinesterasic (AChE and BuChE) activities were observed for roots ethanolic extract of C. leprosum and arjunolic acid, suggesting both as promising targets for the development of innovative multi-functional medicines for Alzheimer desease treatment.
