LC-MS/MS method for quantifying aescinate A and B and assessing their relationship with phlebitis.

The purpose of this study is to establish and validate a sensitive, robust and rapid liquid chromatography-tandem mass spectrometry method for quantifying the aescinate A and aescinate B in human plasma and assessing the association of phlebitis and aescinate A and aescinate B in vivo exposure. The chromatographic separation was completed on Agilent ZORBAX SB-C (2.1 mm × 100 mm, 3.
