A precise and selective high-performance liquid chromatographic (HPLC) method with diodearray detection for quantifying huperzine A in formulated products was developed and validated. A liquid chromatographic-mass spectrometric (LC/MS) procedure was devised to confirm the HPLC method. Huperzine A was dissolved in 1,2-dichloroethane, chromatographed on a YMCBasic C18 column, and detected at 308 nm. A gradient mobile phase of 10 mM ammonium acetate (pH=3.5)-methanol was used.
