Abstract:

Higenamine is an active ingredient of Aconite root in Chinese herbal medicine and might be used as a new agent for a pharmaceutical stress test and was approved to undergo clinical pharmacokinetic study. Therefore, there exists a need to establish a sensitive and rapid method for the determination of higenamine in human plasma and urine. This paper described a sensitive and rapid method based on liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) for the determination of higenamine in human plasma and urine. Solid-phase extraction (SPE) was used to isolate the compounds from biological matrices followed by injection of the extracts onto an Atlantis dC18 column with isocratic elution. The mobile phase was 0.05% formic acid in water-methanol (40:60, v/v). The mass spectrometry was carried out using positive electrospray ionization (ESI) and data acquisition was carried out in the multiple reaction monitoring (MRM) mode. The method was fully validated over the concentration range of 0.100-50.0 ng/mL and 1.00-500 ng/mL in plasma and urine, respectively. The lower limits of quantification (LLOQs) were 0.100 and 1.00 ng/mL in plasma and urine, respectively. Inter- and intra-batch precision was less than 15% and the accuracy was within 85-115% for both plasma and urine. Extraction recovery was 82.1% and 56.6% in plasma and urine, respectively. Selectivity, matrix effects and stability were also validated in human plasma and urine. The method was applied to the pharmacokinetic study of higenamine hydrochloride in Chinese healthy subjects.
