Complanatoside A
Complanatoside A is a flavonol glycoside isolated from Astragalus complanatus, and currently it is used as a quality control index for A. complanatus in the 2010 edition of the Chinese Pharmacopoeia.

Biological Activity
A simple and sensitive LC-MS/MS method is developed for the determination of complanatoside A in rat plasma over the range of 2.3–575 ng/mL. Complanatoside A is extracted from plasma by a protein precipitation procedure, separated by LC and detected by MS/MS in positive electrospray ionization mode. The lower limit of quantification is established at 2.3 ng/mL. Intra- and inter-day precisions (LLOQ, low-QC, med-QC and high-QC) are less than 7.9%, and accuracies are between 94.0 and 105.1%. Matrix effect is acceptable (97.9–103.0%) and extraction recovery is reproducible (88.5–94.4%). Complanatoside A is stable in the investigated conditions. The method is applied to the pharmacokinetics of complanatoside A in rats[1].

Solvent & Solubility
DMSO : ≥ 35.7 mg/mL (55.56 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.

Protocol
Rats: The rats are fasted for 12 h before the experiment. Complanatoside A is formulated in water and a single dose of 30 mg/kg is administered by oral gavage. Blood samples are obtained from the vena orbitalis just prior to dose and at 0.083, 0.167, 0.25, 0.5, 0.75, 1, 2, 3, 5, 7, 10 and 14 h after administration. After centrifugation at 6000g for 10 min, the upper plasma is collected and stored at–20°C before analysis. The data are calculated by Drug&Statistics software[1].
