A simple and fast capillary gas chromatographic (CGC) method
with flame ionization detection is developed for the analysis of fatty oil
in Semen Ziziphi Spinosae. After methyl-esterification, eight components are
identified by gas chromatography–mass spectrometry. The derivatization
condition is investigated in order to validate this method. Palmitic acid and
stearic acid are quantitated simultaneously. The limits of detection are 5.024 µg/mL
for palmitic acid and 6.957 µg/mL for stearic acid, respectively. The
limits of quantitation are 16.76 µg/mL for palmitic acid and 23.19 µg/mL
for stearic acid, respectively. The percent recoveries of palmitic and stearic
acid are 97.4% and 96.6%. CGC is shown to be a quick and informative tool for
the analysis of fatty oil in Semen Ziziphi Spinosae.
