Background: Salidroside, one of the main active ingredients in Fructus Ligustri Lucidi (FLL), is well demonstrated to exert anti-osteoporotic effect. However, the plasma pharmacokinetic profile of salidroside in FLL in estrogen-deficient rats remains unknown. Objective: The objective was to develop a sensitive, rapid, and accurate ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) method for the determination of the pharmacokinetics profile of salidroside after oral administration of FLL aqueous extract in normal and ovariectomized (OVX) rats. Materials and Methods: OVX and normal rats were orally administrated with FLL at a bolus of 7 g/kg. Plasma samples were precipitated by methanol, and the supernatant was chromatographed by a Waters BEH C18column with a gradient elution of ammonium acetate and acetonitrile. Quantification was carried out on the electrospray ionization, positive multiple reaction monitoring modes. Results: The lower limit of detection was 50 ng/mL, and the dynamic linear range was 50–30,000 ng/mL with a value of R2 > 0.99. The intra- and inter-day precisions were lower than 14.67%, and accuracy was in the range of 99.29%–103.37%. The recovery of salidroside ranged from 88.90% to 101.78%, with the matrix effect ranging from 85.53% to 100.45%. The t1/2, MRT0–∞, and apparent volume of distribution for salidroside increased in OVX rats. Conclusion: A sensitive, accurate, and rapid method was successfully established and validated for the determination of plasma characteristics of salidroside in Sprague–Dawley (SD) rats. The results suggest that ovariectomy could interfere with salidroside metabolism in SD rats.
