Identification of chemical components in Baidianling Capsule based on gas chromatography–mass spectrometry and high‐performance liquid chromatography combined with Fourier transform ion cyclotron resonance mass spectrometry

Baidianling Capsule, which is made from 16 Chinese herbs, has been widely used for treating vitiligo clinically. In this study, the sensitive and rapid method has been developed for the analysis of chemical components in Baidianling Capsule by gas chromatography–mass spectrometry in combination with retention indices and high‐performance liquid chromatography combined with Fourier transform ion cyclotron resonance mass spectrometry. Firstly, a...
