Vincristine sulfate liposome is a liposomal formulation of vincristine sulfate, a traditional anticancer drug, encapsulated in the aqueous core of phospholipid/cholesterol liposomes, which are kinds of targeted carriers to enhance malignancy targeting, exposure and anticancer activity of the drug. To evaluate and compare the pharmacokinetics of nonliposomal and liposome-encapsulated VCR and pharmacodynamic relationships associated with the toxicity and the efficacy behavior, it is essential to have a reliable method of separating the free and liposomal forms of the drug. In this paper, we have developed and validated methods to quantify the free vincristine (F-VCR) and total vincristine (T-VCR) in human plasma after intravenous administration of vincristine sulfate liposome injection (VSLI). The methods involve solid-phase extraction (SPE) for separating the F-VCR and liquid-liquid extraction (LLE) for releasing the VCR totally from the liposomal forms followed by an ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method. The detection was performed on a triple quadrupole tandem mass spectrometer in multiple reaction monitoring (MRM) mode using positive electrospray ionization (ESI). The methods were validated over the concentration range of 0.2-50 ng/mL for F-VCR and 0.5-400 ng/mL for T-VCR, respectively. Inter- and intra-day precision (RSD%) were
