Abstract:

The extraction, purification and GC-MS analysis of terpenoid compounds from Grateloupia filicina C.Ag. were investigated in the present study. The supercritical fluid extraction conditions of terpenoid compounds from Grateloupia filicina C.Ag. were optimized by orthogonal test, and the main components in the terpenoid compounds were analyzed by GC-MS. The results of orthogonal test showed that the extraction pressure presented the most significant effect on yield of terpenoid compounds, followed by extraction duration, temperature and flow rate in turn, and the optimum extraction conditions were as follows: with flow rate of 10 L/h, extraction at 30 MPa and 40 ℃ for 2 h. By searching in NIST98 spectrum library and refering to related literature, finally 11 kinds of terpenoid compounds were confirmed from the extract of Grateloupia filicina C. Ag.

Key words: Grateloupia filicina C. Ag., terpenoid compounds, supercritical fluid extraction, gas chromatography-mass spectrometry (GC-MS)
