In order to control the herbal quality, validation of rosmarinic acid determination using high-performance liquid chromatography was developed. The objective of this report was to validate an HPLC technique for assessing rosmarinic acid levels. and application that method to determine rosmarinic acid in &lt;em&gt;Rosmarinus officinalis, Symphytum officinale, Mentha piperita, Orthosiphon stamineus &lt;/em&gt;and &lt;em&gt;Salvia officinale.&lt;/em&gt; &lt;strong&gt;Methods&lt;/strong&gt;: The chromatographic separation was carried out on a reversed-phase C18 column with a mobile phase of 0,1% formic acid and acetonitrile and an isocratic elution at a flow rate of 0,5 mL/min. The wavelength for detection was set to 330 nm. The method has been validated for precision, accuracy, linearity, limit of detection, and limit of quantitation. &lt;strong&gt;Result:&lt;/strong&gt; The concentration response of the detector was linear, with a coefficient of determination of 0.9933. The HPLC technique had an accuracy of 101,00 ± 6,43%. The precision was 6,36% when expressed as a coefficient of variation (CV). The highest level of rosmarinic acid was 214,86 ± 0,60 μg/mL in &lt;em&gt;Rosmarinus officinalis&lt;/em&gt; extract.&lt;strong&gt; Conclusion:&lt;/strong&gt; The HPLC method was valid to analyse rosmarinic acid level. The method can be applied in routine determination of rosmarinic acid of phytopharmaceutical products.&lt;/p&gt;
