Abstract:
It's established a high-performance liquid chromatography-time of flight mass spectrometry(HPLC-TOF-MS) method to analyze chemical constituents in Salvia chinensis. The separation was performed on a SHISEIDO MG C18 reverse phase column (3.0 mm x 100 mm, 3 microm). The mobile phase consisted of acetonitrile (A) and water (containing 0.1% formic acid, B) was used as gradient elute. The gradient of a phase, 10%-90% (0-33 min), 90% (33-40 min). The flow rate was 0.6 mL x min(-1). Post-column split ratio was 2:1. Temperature of column was 25 degrees C. Time-of-flight mass spectrometer (TOF-MS) and electrospray ion source (ESI) was applied for qualitative analysis under positive ion mode, and mass scan range was m/z 100-1 000. As a result,28 of the major chemical constituents of S. chinensis were identified by HPLC-TOF-MS. In this study, a rapid and efficient method for studying the chemical constituents in S. chinensis by HPLC-TOF-MS was established, which paves a way for the quality control and further studies of the herb in vivo.
