695 RESVERATROL - HPLC METHOD
By Special Request
Quantitation of resveratrol by HPLC with tandem mass spectrometry detection.
Summary:This method quantitatively determines the amount of the resveratrol in botanical materials. Freeze dried samples are extracted by homogenization with methanol, followed by heating at 60 degrees for 30 minutes and analyzed by HPLC with tandem mass selective detection. The analysis uses a Phenomenex SynerGi Hydro-RP (150 mm x 4.6 mm) HPLC column at a flow rate of 0.75 mL min-1 and a gradient elution using methanol:water. The method has a detection limit of 0.2 ppm.
