Abstract
OBJECTIVE: To study the polysaccharide and lipid components of Cinnamomi Cortex by GC-MS and provide experimental evidence for its exploitation. METHODS: The polysaccharide components of Cinnamomi Cortex were extracted,and hydrolyzed with trifluoroacetic acid (TFA) and followed by adding hydroxylamine hydrochloride, pyridine and acetic anhydride acetylation for reaction. After that, spectrometry of polysaccharides was measured by GC-MS. Lipid components were esterified and identified by GC-MS. RESULTS: 6 kinds of polysaccharide components were identified by GC-MS. D-glucofuranose accounted for 38.64%, which was the most proportion. 13 kinds of fatty acids were identified, accounted for 72.68% in total lipids. 5 kinds of unsaturated fatty acids accounted for 13.83% and 8 saturated fatty acids accounted for 58.85%. CONCLUSION: There are many kinds of polysaccharide and lipid components in Cinnamomi Cortex and GC-MS can analyze the polysaccharide and lipid components of Cinnamomi Cortex effectively.
