Objective: To establish a method to determine the content of costunolide in Laurus nobilis leaves by high-performance liquid chromatography (HPLC). Materials and Methods: The separation was performed on a reversed-phase C18 column (100 Å, 150 mm × 4.6 mm, 5 μm pore size) using a mobile phase composed of water:acetonitrile (40:60) at a flow rate of 1.0 ml/min. The detection was carried out on a ultraviolet detector at 210 nm. The developed method was validated according to the requirements for International Conference on Harmonisation guidelines. Results: The proposed method for costunolide was validated for linearity with excellent correlation coefficient (r2 > 0.999). The relative standard deviation (RSD) is less than 1% in precision (i.e repeatability and intermediate) of the method. The recovery rate for costunolide was within 100.54%–102.62%. The limit of detection and limit of quantitation were 2.29 and 6.64 parts per million, respectively. Conclusion: The developed HPLC method is simple, rapid, precisely, accurately, and widely accepted and it is recommended for efficient assays in routine work. Abbreviation Used: HPLC: High-performance liquid chromatography; UV: Ultraviolet; ICH: International Conference on Harmonisation; r2: Correlation coefficient; WHO: World Health Organization; ppm: Parts per million; % RSD: Percentage relative standard deviation
