Abstract
The method of UHPLC-LTQ-Orbitrap mass spectrometry coupled with higher energy collision dissociation (HCD) was established to rapidly analyze the constituents absorbed into blood after oral administration of steroidal saponins from Radix Ophiopogonis. A total of 31 constituents, including 13 furostanol steroidal saponins and 18 spirostanol steroidal saponins, were characterized based on the accurate mass measurements, fragmentation patterns, chromatographic retention times, and diagnostic product ions. Among them, 8 compounds were unambiguously identified by comparison with their corresponding standards. The results provide comprehensive insights and guidance for elucidation of material basis of Radix Ophiopogonis activity.
