AIM: To separate and quantitatively determine six alkaloids: aconitine, mesaconitine, hypaconitine, beiwutine, benzoylaconine and benzoylmesaconine in the Chinese traditional medicine Radix Aconiti Lateralis Preparata (Fuzi). METHODS: A RP-ion-pair HPLC method was established. An AichromBond-1 C18 column was used at a column-temperature of 35 degrees C. The mobile phase was CH3CN5 mmol x L(-1) NaH2PO4(50:50) containing 7 mmol x L(-1) SDS at a flow-rate of 1.0 mL x min(-1). The detector was set at UV 235 nm. RESULTS: These six alkaloids can be completely separated and determined quantitatively. CONCLUSION: This method is accurate and suitable for the determination of six alkaloids in Fuzi.
