A validated high performance liquid chromatographic method was developed for the determination of chromium picolinate in pharmaceutical dosage forms. The analysis was performed at room temperature using a reversed‐phase Supelcosil LC‐18 (250 × 4.6 mm, 5 µm) column. The mobile phase consisted of acetonitrile:water (40:60 v/v) at a ow rate of 0.8 mL/min. The UV‐detector was set at 264 nm. The developed method showed a good linear relationship in the concentration range from 0.125 to 12.5 µg/mL with a correlation coefcient from 0.999. The limit of detection and limit of quantication were 0.091 and 0.181 µg/mL, respectively. Copyright © 2004 John Wiley & Sons, Ltd.
