RESUMO: 

Neste estudo, uma técnica de cromatografia líquida de alta resolução em fase reversa
(CLAE-FR) para a determinação de ácido rosmarínico em Cordia verbenacea foi desenvolvida
e validada. A análise de regressão foi avaliada, com observação de uma boa linearidade (r
= 0,9997). Os valores obtidos para a precisão e exatidão estão de acordo com as diretrizes
do ICH e com a legislação brasileira. Os valores de repetibilidade e precisão intermediária
foram 2,79% e 4,76%, respectivamente. Os limites de detecção e de quantificação de ácido
rosmarínico foram de 1,92 µg/mL e 5,81 µg/mL, respectivamente. Os resultados mostraram
que o método desenvolvido é uma técnica por CLAE-FR de confiança para a determinação
de ácido rosmarínico em tintura de C. verbenacea. Além disso, essa metodologia foi aplicada
em estudo sazonal, que revela uma correlação positiva relativamente forte entre o período de
chuvas e o teor de ácido rosmarínico.

ABSTRACT: 

Determination of rosmarinic acid in Cordia verbenacea by liquid
chromatography: applicability in seasonal study. In this study, a reverse phase-high
performance liquid chromatography (RP-HPLC) technique for determination of rosmarinic acid
in the Cordia verbenacea was developed and validated. A regression analysis was performed,
with the observation of good linearity (r =0.999949). The values obtained for precision and
accuracy determination are in agreement with ICH guidelines and the Brazilian legislation.
The values of repeatability and intermediate precision were 2.79% and 4.76%, respectively.
The detection and the quantitation limits of the rosmarinic acid were 1.92 µg/mL and 5.81 µg/
mL, respectively. The results demonstrated that the developed method is a reliable RP-HPLC
technique for the determination of rosmarinic acid in C. verbenacea tincture. In addition, this
methodology was applied at a seasonal study indicating relatively strong positive correlation
between the rain period and the rosmarinic acid content.
