[Quality Analysis and Evaluation of Anemarrhena asphodeloides Rhizome from Different Habitats]

tive: To compare and analyze the quality of Anemarrhena asphodeloides rhizome from different habitats.

Simultaneous determination of nine components in Anemarrhena asphodeloides rhizome by UPLC-TQ/MS was performed on a Phenomenex Kinetex XB-C18 (100 mm x 2.1 mm, 1.7 μm) column with the mobile phase consisted of 0.1% formic acid-acetonitrile (gradient elution) at the flow rate of 0.4 mL/min and thecolumn temperature at 35 degrees C. Multiple reaction mode detection (MRM) in mode was used in this assay.

Nine components were separated totally within 15 min. Good correlation were found between the investigated compounds concentrations and their peak areas within the test ranges with the correlation coefficient from 0.9917 to 0.9992. The average recoveries were from 98.1% to 103.7%, and the RSD of precision was in the range of 1.7% - 4.7%. 0.074-3.620 mg/g for sarsasapogenin, 0.042-2.530 mg/g for timosaponin A III, 22.1- 50.4 mg/g for timosaponon B II, 0.10 -8.28 mg/g for officinalisinin II, 0.64 -7.29 mg/g for anemarsaponin B III, 3.28 -27.40 mg/g for mangiferin, 1.83 - 7.21 mg/g for isomangiferin, 0.36 -9.25 mg/g for neomangiferin and 4.72 x 10(-5) - 1.38 x 10(-3) mg/g for baohuoside I in Anemarrhena asphodeloides rhizome from different habitats were detected.

The method is rapid, accurate and can be used for quality evaluation of Anemarrhena asphodeloides rhizome. The quality of Anemarrhena asphodeloides rhizome from different habitats are different. The saponins content of Anemarrhena asphodeloides rhizome in Hebei is higher than that of the others.
