Triterpenes were separated on a Dionex HPG 3200 HPLC system (Thermo Scientific) equipped with a 150 x 2.1 mm, 2.7 μm, Cortecs C8 column (Waters) with a binary gradient system. Mobile phase A consisted of water + 0.1% formic acid (FA) and mobile phase B consisted of methanol + 0.1% FA.
For MS/MS optimization, a 15 μmol/L Hcy solution was prepared in 500 mL/L acetonitrile-500 mL/L water containing 0.25 mL/L formic acid and infused at a flow rate of 10 μL/min. In the multiple reaction monitoring (MRM) mode, the instrument was optimized automatically by the built-in algorithm to monitor the 136.1 to 90 m/z and 140.1 to 94 m/z
