متن کاملDetermination of Ursolic Acid and Ursolic Acid Lactone in the Leaves of Eucalyptus tereticornis by HPLC
Um método simples, isocrático, de HPLC foi desenvolvido para quantificação simultânea de dois triterpenos bioativos, ácido ursólico e lactona do ácido ursólico em folhas de E. tereticornis. As amostras foram analisadas em coluna RP-18 (4,6 × 250 mm, 5 μm) com metanol e água acidificada a pH 3,5 com TFA (88:12) a 210 nm. O método foi validado e aplicado para a quantificação simultânea dos triter...
