Type II ceramides were separated according to the length of their fatty acid alkyl chain using two column system. The packing of the first column was non-polar adsorbent prepared by coating of macroporous spherical silica with cationized poly(vinyl alcohol) of low substitution degree. Commercial normal phase column Lichrosorb Si 60 was used as a second column in this system. Elution was performed in an isocratic mode using methanol:chloroform 50:50 (v/v) as an eluent. 相似文献
