| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Development and validation of a liquid chromatography-tandem mass spectrometry method for the determination of xanthinol in human plasma and its application in a bioequivalence study of xanthinol nicotinate tablets.[Pubmed:18718822]
J Chromatogr B Analyt Technol Biomed Life Sci. 2008 Sep 15;873(1):20-6.
A sensitive, rapid liquid chromatographic-electrospray ionization mass spectrometric method for the determination of xanthinol in human plasma was developed and validated. Xanthinol nicotinate in plasma (0.5 mL) was pretreated with 20% trichloroacetic acid for protein precipitation. The samples were separated using a Lichrospher silica (5 microm, 250 mm x 4.6 mm i.d.). A mobile phase of methanol-water containing 0.1% formic acid (50: 50, v/v) was used isocratically eluting at a flow rate of 1 mL/min. Xanthinol and its internal standard (IS), acyclovir, were measured by electrospray ion source in positive selected reaction monitoring mode. The method demonstrated that good linearity ranged from 10.27 to 1642.8 ng/mL with r=0.9956. The limit of quantification for xanthinol in plasma was 10.27 ng/mL with good accuracy and precision. The mean plasma extraction recovery of xanthinol was in the range of 90.9-100.2%. The intra- and inter-batch variability values were less than 4.8% and 7.9% (relative standard deviation, R.S.D.), respectively. The established method has been successfully applied to a bioequivalence study of two Xanthinol nicotinate tablets for 20 healthy volunteers.
Xanthinol Nicotinate (Xanthinol Niacinate), a vasodilator, can act directly on the smooth muscle of small arteries and capillaries. Xanthinol Nicotinate expands blood vessels, improves blood rheology and reduces peripheral vascular resistance.
