GLBD has been eluted at 6.36 min. Linearity was obtained over a concentration range of 5–50 μg/ml (r2>0.999). The Limit of detection (LOD) and Limit of quantitation (LOQ) were found to be 0.1 μg/ml and 05. μg/ml respectively. The mobile phase consisted of acetonitrile and water in the ratio of (60: 40, v/v), respectively. The analysis time was 10 min at a 1.0 ml/min flow rate. The UV detection was carried out at 228 nm. The RP - HPLC assay method developed for GLBD is rapid, precise, accurate, and specific. The method may be used for assessing the stability of GLBD as a bulk drug and in its pharmaceutical nanoemulsion formulations. The RT less than 10 min which was found to be practicably advantageous for the use of this method in routine analysis.
