چکیده

A investigação química das plantas Phyllanthus cochinchinensis (Euphorbiaceae) levou ao isolamento de três novos glicosídeos fenólicos, filantuosídeos A-C, juntamente com 12 compostos conhecidos. Suas estruturas foram determinadas com base em extensivas análises espectroscópicas e métodos químicos. Dentre eles, filantuosídeos A e B são dois glicosídeos fenólicos raros, com um esqueleto C6-C3-C6. A configuração absoluta dos filantuosídeos A e B foi estabelecida por dicroísmo circular elétrico calculado (ECD) usando teoria do funcional da densidade e a sua abordagem dependente do tempo (TDDFT). Os compostos isolados também tiveram sua citotoxicidade e atividade antimicrobial testadas.
