An FPLC-RID coupled with AEC and SEC method was firstly used for preparation and purification of high purity XOSs.
The XOSs with degree of polymerization 2–6 from xylan were separated and purified.
The XOSs was rapid analyzed by HPTLC and HPLC-CAD.
The XOSs were further identified by MALDI-TOF-MS and GC–MS analysis.
