Study on tissue distribution of curcumin solid lipid nanoparticles in rats
To study the tissue distribution characteristics of curcumin solid lipid nanoparticles (Cur-SLN) in rats.
METHODS
2
Cur-SLN was prepared with microemulsion. SD rats were randomly divided into Cur raw material group and Cur-SLN group, with 45 rats in each group. The rats of two groups were injected with the corresponding drugs (by Cur, 25 mg/kg) by single intravenous injection. The heart, lung, kidney and liver tisse were separated at 0.25, 0.5, 1, 2, 4, 6, 8, 12 and 24 h after administration. The contents of Cur in different tissues were determined by high-performance liquid chromatography method. Their tissue distribution was analyzed.
RESULTS
2
The linear range of detected mass concentration of Cur in heart, lung, kidney and liver tissues were 0.064 75-129.50, 0.064 75-64.75, 0.064 75-129.50, 0.064 75-129.50 μg/mL, respectively (all
r
>0.99). The lower limits of quantitation were all 0.064 75 μg/mL, and the limit of detection were all 0.012 95 μg/mL. The intra-day and inter-day precision, accuracy and extraction recovery were in line with the requirements of quantitative analysis. Compared with Cur raw material group, the contents of Cur in heart, kidney, lung (at each time point of 0.25-24 h) and liver tissue (at each time point of 0.25-1 h, 12-24 h) of samples were significantly increased in the Cur-SLN group (
P
<0.05 or
P
<0.01), while the contents of Cur in liver tissue (at each time point of 2-8 h) were significantly decreased (
P
<0.01).
CONCLUSIONS
2
After Cur was prepared into solid lipid nanoparticles, its distribution in heart, kidney and lung tissues is increased.
