measuring OAS

Does anyone know how to seperate and detect (and therefore measure) O-acetyl
serine (OAS) in plant extracts. This is a precursor in cysteine synthesis. 

In preference we would like some kind of HPLC or GC based method. One
particular problem is the rapid spontaneous conversion to the N-acetylated form
that occurs in solution, at alkaline pH. 

Thanks, Malcolm
