Figure 5.The characteristic of the altered content lyso phosphatidylcholine (LPC) and platelet-activating factor (PAF). Orbitrip coupled with HPLC detected altered content metabolites with the m/z = 496.3324 and 518.3168 that were continuously eluted in 34 - 41 minutes (A). The structure information obtained from Orbitrip showed m/z = 496.3324 is a kind of LPC (B), and m/z =518.3168 is a kind of PAF (C).
