Figure 4. Farnesol production of BWP17-DPP3-GFP cells stimulated by bisbibenzyls.

The cells were pretreated with A1, A3, A5 and FLC at 37°C for 12 hours and the farnesol amounts were determined by HPLC-MS. A) The retention time of farnesol eluting at 20.29 min. B) MS profile showed a molecular ion of m/z 221.2 and 222.2. C) Values of ordinate represents the increased folds of farnesol treated by tested agents compared with control.
